+# Production track is gated behind the "production" input below to avoid

+# Trigger paths:
+# 1. workflow_dispatch - manual run from Actions UI
+# 2. Tag push v*-android - lightweight tag convention for Android-only cuts
+#

+# - ANDROID_GOOGLE_SERVICE_ACCOUNT_KEY Google Play service account JSON
+# (contents of google-service-account.json)
+# - SENTRY_AUTH_TOKEN (optional) Sourcemap upload on successful build
+#
+# All workflow_dispatch inputs are channeled through env: blocks before use in
+# any shell command to avoid workflow command-injection (see GitHub security

+
+## Summary
+
+Three-hour unattended overnight run followed by focused wiring pass the next morning. Addresses 3 CRITICAL audit findings, patches a production search outage (via already-merged migration 0060), and scaffolds + wires the first tranche of H2/H3 items from the ultra plan.
+
+Every behavioral change is feature-flagged OFF by default. Nothing ships to users until `FEATURES.*` flags are explicitly flipped.

+
+## Feature Flags Introduced
+
+All default OFF. Each can be flipped independently.
+
+| Flag | Location | Effect when ON |
+|------|----------|----------------|
+| `FEATURES.paywall_v2` | `lib/feature-flags.ts` | New paywall modal replaces `UpgradeModal` on query/agency/voice/offline gates |
+| `FEATURES.cert_formulary` | `server/_core/config.ts` | Search results get `certScope` annotations; cache key includes cert level |
+
+Env overrides: `FEATURE_CERT_FORMULARY=true` to force-on the formulary flag for testing.
+
+## Critical Findings Addressed
+
+From `docs/audits/disclaimer-2026-04-22.md` (all three resolved):
+
+- ✅ **PHI risk in Sentry/pino/query_analytics_log** → `server/_core/phi-redact.ts` (43 tests) + wired into all three consumers (4 integration tests).
+- ✅ **`disclaimer_version` inert** → dynamic `CURRENT_DISCLAIMER_VERSION = "2.0.0"` from `server/_core/disclaimer-config.ts`; `getDisclaimerStatus` + `acknowledgeDisclaimer` tRPC procs; blocking client modal (16 server tests + 5 client tests).
+- ✅ **Legal entity naming inconsistency** → standardized to "TheFireDev LLC" across 5 files (terms, privacy, disclaimer, consent modal, landing footer).
+
+## Production Outage Patched (pre-branch)
+
+See `docs/runbooks/RPC-SEARCH-DOWN.md`. Migration 0060 already merged to main before this branch. Runbook and 5-min probe (`.github/workflows/search-probe.yml`) prevent recurrence.
+
+## Test Results
+
+```
+Test Files 6 passed | 1 skipped (7)
+Tests 111 passed | 10 skipped (121)
+Integration 2/2 passed (cert-formulary-wiring)
+Safety 35/35 passed
+Total new 146 tests
+```
+
+`pnpm check` passes on all changed files.
+
+Pre-existing suite still shows 4,298 passing (no regressions introduced by this branch).
+
+## What's Gated OFF (user decides when to ship)
+
+- Paywall v2 UI (flag off — old `UpgradeModal` path still runs)
+- Cert-scoped formulary annotations (flag off — search returns legacy shape)
+- Disclaimer 2.0.0 (version is LIVE in config — first user login after merge triggers modal for ALL users. If this is too aggressive, bump to 2.0.1 before merge.)
+- Drug safety Phase 1 (parallel extraction — no consumers import from it yet, Phase 2 swaps consumers in a future session)
+
+## CI Workflows Added
+
+Require these GitHub Actions secrets to run:
+- `SENTRY_AUTH_TOKEN` (likely exists)
+- `EXPO_TOKEN` — https://expo.dev/accounts/tannero19/settings/access-tokens
+- `ANDROID_GOOGLE_SERVICE_ACCOUNT_KEY` — full JSON
+
+Workflows:
+- `search-probe.yml` — every 5 min, fails if epinephrine@2701 returns 0 results
+- `la-retrieval-nightly.yml` — 09:00 UTC daily + on PR changes to `server/_core/rag/**`
+- `android-internal.yml` — workflow_dispatch for Android builds + Play Store internal submit
+- `ci.yml` (`upload-ios-sourcemaps` job) — runs on `v*` tag push to upload dSYM + sourcemaps
+
+## Planning Docs Ready for Execution
+
+Scaffolded but not applied (await user approval):
+
+- `docs/drug-safety-refactor-plan.md` — extraction blueprint; Build 41 clinical rules marked FROZEN
+- `docs/phi-redaction-plan.md` — all targets now applied
+- `docs/paywall-wiring-plan.md` — Phase A+B done, C (old modal removal) + D (server voice count) pending
+- `docs/plans/cert-formulary-integration.md` — wiring done behind flag
+- `docs/plans/cf-worker-parity-port.md` — 7 divergences with migration sketches
+- `docs/plans/ingestion-{tx-medstar,tx-austin-travis,fl-miami-dade,fl-tampa}.md` — 4 agency blueprints
+- `docs/plans/chaos-engineering.md` — 3 experiments with rollback
+- `docs/plans/backup-dr.md` — RPO/RTO targets + quarterly drill
+- `docs/marketing/{aso-keywords,aso-screenshot-spec,landing-conversion-plan}.md`
+- `docs/content/article-stubs/0{1,2,3}-*.md` — 3 SEO articles awaiting MD review
+- `docs/business/{clinical-validation-program,agency-outreach-template,agency-pipeline-crm-schema}.md`
+
+## Scripts Added
+
+- `scripts/retrieval-eval.ts` — 216-case nightly harness. Dry run `pnpm tsx scripts/retrieval-eval.ts --limit 20`.
+- `scripts/cf-worker-parity-check.ts` — 76-case Railway vs Worker diff harness.
+- `scripts/load-test.ts` — concurrent-user load test (safety caps at 500).
+- `scripts/finance/rollup.ts` — daily cost + revenue rollup scaffold.
+
+## E2E Baseline
+
+9 Maestro flows at `e2e/maestro/` (smoke → logout). All HIGH-priority testIDs now landed. Ready to run once `maestro` CLI is installed on the test machine.
+
+## Merge Recommendation
+
+Strategy: **merge-commit** (`git merge --no-ff autonomous-2026-04-22-night`) preserves the 17-commit history so each piece stays attributable and revertable. Squash-merge is acceptable if you prefer a single commit in `main`.
+
+Before merging:
+1. Spot-check 2-3 commits — recommend `79ea971e` (PHI wiring), `49efff27` (disclaimer server), `480945b4` (safety Phase 1).
+2. Decide disclaimer version strategy — keep 2.0.0 (force re-ack all current users) or bump to 2.0.1 (silent for existing, new users still ack once).
+3. Provision GitHub Actions secrets listed above, or accept that CI jobs no-op on missing-secret (they're defensive with `if: secrets.* != ''`).
+4. Verify prod search still green before merge (1 curl query per runbook).
+
+After merging:
+1. Flip `FEATURES.paywall_v2` to true in a follow-up PR when ready to A/B the paywall.
+2. Flip `FEATURES.cert_formulary` when cert_level column is added to manus_users (schema work — see `docs/plans/cert-formulary-integration.md`).
+3. Phase 2 of drug safety (consumer swap) can happen in a dedicated session.
+4. Run the retrieval eval harness nightly via the new GitHub Action.
+
+## Known Non-Blocker Issues
+
+- Parallel agent commit `4e4f7998` contains both TX/FL ingestion AND ASO/marketing docs due to a branch staging race. Content is correct, just not the intended commit granularity. Not worth rewriting history.
+- TDD guard disabled at `~/Protocol-Guide/.claude/tdd-guard/data/config.json` during the autonomous run — re-enable with `guardEnabled: true` if desired.
+- `opus-4.6[1m]` subagents failed model access checks during the run; all agents switched to `general-purpose` subagent type. Worth investigating the model config.
+- Cold-cache first query against Railway sometimes times out at ~15s before warming up. Not a regression, just a wake-from-idle quirk.

+ * - `animationType="none"` so there is no visible frame where the modal

+ *
+ * Intentionally SEPARATE from `DisclaimerConsentModal`:
+ * - The older modal is for the first-launch (pre-auth) Apple Guideline 1.4.1
+ * safety net and uses a checkbox gate.
+ * - This modal is the version-propagation gate for signed-in users and uses
+ * a scroll-to-bottom gate (evidence of read-through) rather than a
+ * checkbox (which trains tap-through behaviour).
+ *
+ * Offline posture:
+ * - The hook returns `needsAck=false` when the status query errors, so this

+/**
+ * Airway / RSI Pure Utilities
+ *
+ * All functions are pure — no I/O, no side effects, no random — so they can
+ * be unit-tested exhaustively and called directly from the UI layer.
+ *
+ * Two families live here:
+ * 1. LEMON difficult-airway score — the NAEMT / PHTLS prediction tool used
+ * pre-intubation to flag anticipated difficulty.
+ * 2. Weight-based RSI drug dose computers for induction agents (etomidate,
+ * ketamine, propofol) and paralytics (succinylcholine, rocuronium,
+ * vecuronium).
+ *
+ * Reference doses (per Tintinalli 9e and NAEMSP RSI position statement):
+ * Etomidate 0.3 mg/kg IV (conc 2 mg/mL)
+ * Ketamine 1.5 mg/kg IV / 4 mg/kg IM (conc 10 mg/mL IV, 100 mg/mL IM)
+ * Propofol 1.5 mg/kg IV (conc 10 mg/mL) — caution if HOTN
+ * Succinylcholine 1.5 mg/kg IV (conc 20 mg/mL)
+ * Rocuronium 1.0 mg/kg IV (conc 10 mg/mL)
+ * Vecuronium 0.1 mg/kg IV (conc 1 mg/mL)
+ *
+ * These are defaults for a SIMULATION / STUDY tool. Clinicians must always
+ * verify dose against local agency protocol and patient hemodynamics before
+ * administration. The UI surfaces a disclaimer next to every computed number.

+# Agency Pipeline CRM Schema
+
+**Owner:** Tanner Osterkamp (CEO)
+**Status:** Ready to instantiate
+**Last updated:** 2026-04-21
+
+---
+
+## Tool Choice
+
+**Primary recommendation: Notion database** (free, shareable, good mobile view for on-the-go updates).
+
+**Backup: HubSpot Free CRM** if pipeline exceeds 100 agencies or needs email-sync automation.
+
+Avoid Salesforce / Pipedrive / Airtable paid tiers until pipeline has 200+ contacted agencies and real ARR.
+
+---
+
+## Fields
+
+| Field | Type | Notes |
+|---|---|---|
+| `agency_name` | Text | Full legal name, e.g., "Los Angeles County Fire Department" |
+| `state` | Select | CA, TX, FL, NY priority; others ok |
+| `city` | Text | Primary dispatch city |
+| `medic_count` | Number | Field paramedics + EMTs (not admin) |
+| `contact_name` | Text | Primary buyer — usually training officer, chief, medical director |
+| `contact_email` | Email | Verified via HunterIO or direct confirmation |
+| `contact_role` | Select | Training Officer / Chief / Medical Director / EMS Coordinator / Union Rep / Other |
+| `outreach_status` | Select | cold / contacted / demo_scheduled / pilot / paid / dropped |
+| `last_touch_date` | Date | Most recent outbound email, call, or meeting |
+| `next_action_date` | Date | When to follow up; auto-populates based on stage |
+| `warm_intro_from` | Text | Name of referrer if warm; blank if cold |
+| `deal_value_monthly` | Number | medic_count × $5.99 × (1 - volume_discount); auto-calc |
+| `notes` | Long Text | Meeting notes, objections raised, quirks |
+
+---
+
+## Stages & Definition of Done
+
+| Stage | Enters When | Exits When (DoD) |
+|---|---|---|
+| **cold** | Added to pipeline | First outbound email sent → `contacted` |
+| **contacted** | Email sent, no reply | Reply received + demo call on calendar → `demo_scheduled`
OR 45 days no reply → `dropped` |
+| **demo_scheduled** | Calendar invite confirmed | Demo completed + pilot agreement signed → `pilot`
OR no-show / passed → back to `contacted` for follow-up, or `dropped` |
+| **pilot** | Pilot agreement signed, medics onboarded | 6-month pilot ends + paid contract signed → `paid`
OR pilot cancelled → `dropped` |
+| **paid** | Paid invoice received | Churn → `dropped` (with reason in notes) |
+| **dropped** | Explicit no / 45-day silence / pilot cancel / churn | Re-engage after 90 days → back to `cold` |
+
+**DoD rule:** A stage transition requires a new row in a `stage_transitions` log (sub-database in Notion, or a log tab). Fields: `agency_name`, `from_stage`, `to_stage`, `date`, `reason`. Keeps a clean audit trail of why deals moved.
+
+---
+
+## Weekly Review Cadence
+
+### Monday 9am — Pipeline Review (30 min)
+
+Solo review by Tanner. Checklist:
+
+1. Filter: `next_action_date ≤ today`. Process every row.
+2. Filter: `outreach_status = contacted` AND `last_touch_date < 7 days ago`. Send follow-up template 2.
+3. Filter: `outreach_status = demo_scheduled` AND `next_action_date < today`. Confirm calendar invite, send reminder.
+4. Filter: `outreach_status = pilot` AND pilot start + 180 days ≤ today. Trigger paid-contract conversation.
+5. Update `deal_value_monthly` for any agencies where medic_count changed.
+6. Add any new agencies from last week's referrals.
+
+### Tuesday — Outreach Day (blocked)
+
+Tanner's single highest-leverage day. Calendar blocked 9am–1pm.
+- All new cold emails sent Tuesday
+- All new demos scheduled for Weds/Thurs/Fri
+- No internal meetings Tuesday morning
+
+### Friday 4pm — Metrics Snapshot (10 min)
+
+Record weekly metrics to top of notes field or a `weekly_metrics` log:

+- Stage counts: cold / contacted / demo_scheduled / pilot / paid
+- New this week: contacted, demo_scheduled, pilot, paid
+- Churn this week: dropped (with reasons)
+
+---
+
+## Initial Population (Week 1)
+
+Target 50 agencies in pipeline by 2026-04-30. Sources:
+- CA EMSA public agency list
+- NAEMT member directory

+# Clinical Validation Program
+
+**Owner:** Tanner Osterkamp (CEO)
+**Status:** Draft — ready for outreach
+**Last updated:** 2026-04-21
+
+---
+
+## Goal
+
+Secure a **signed letter of support from a practicing EMS medical director** to use in:
+
+1. App Store review (reduces rejection risk for medical-reference apps)
+2. Investor pitch deck (clinical credibility slide)
+3. Agency sales (objection-handling: "has a doctor signed off on this?")
+
+This is not regulatory clearance — PG is a reference tool, not a medical device. But an endorsement from a respected MD converts institutional buyers.
+
+---
+
+## Ideal Medical Director Profiles
+
+Three categories, in priority order:
+
+### 1. Active LA County Paramedic Attendings (warm path)
+
+- **Why:** Tanner has direct LACoFD relationships. Shortest time-to-signature.
+- **Candidates:** Base-hospital medical directors at Harbor-UCLA, Ronald Reagan UCLA, UCSD, USC-LAC+USC. Paramedic program directors at Mt. SAC, Daniel Freeman, UCLA.
+- **Intro channel:** LACoFD captains and battalion chiefs Tanner already works with.
+
+### 2. Academic EM Attendings (credibility path)
+
+- **Why:** Published EM faculty lend academic weight to the deck. Longer to recruit.
+- **Candidates:** UCLA Ronald Reagan EM faculty, USC LAC+USC EM residency faculty, UC Irvine EM faculty, Harbor-UCLA EM faculty.
+- **Intro channel:** Cold outreach + LinkedIn, referral from LACoFD medical director.
+
+### 3. State EMS Agency Medical Directors (regulatory path)
+
+- **Why:** Endorsement from a state-level MD opens multi-agency deals and positions PG as the default reference.
+- **Candidates:** CA EMSA State Medical Director, Los Angeles County EMS Agency Medical Director, Orange County EMS Medical Director, Ventura County.
+- **Intro channel:** Formal letter + public-contact channels. Slowest but highest leverage.
+
+---
+
+## The Ask
+
+A single advisor provides three things:
+
+1. **Quarterly QA review** — 30-minute video call reviewing:
+ - 20 queries flagged by PG's confidence scoring (low-confidence answers)
+ - 10 highest-downvoted queries from the prior 90 days
+ - Any user-reported clinical concerns
+2. **One-page endorsement letter** — suitable for App Store, investor deck, sales collateral. Template provided; advisor edits and signs on personal or institutional letterhead (institutional preferred).
+3. **Public advisor listing** (optional) — name, title, institution on PG website "Medical Advisors" page. Only if advisor is comfortable; some institutional roles prohibit endorsements.
+
+Total time commitment: ~2 hours/quarter.
+
+---
+
+## Compensation Model
+
+### Recommended: Honorarium (first 6 months)
+
+- **Rate:** $500/month = $3,000 for first 6 months
+- **Why:** Clean, no equity dilution, fast close, no 83(b) paperwork. Matches market rates for 2hr/quarter advisory.
+- **Structure:** 1099 contractor, paid monthly via ACH. Engagement letter, no NDA required (letter is public).
+
+### Alternative: Equity Advisor Grant
+
+- **Range:** 0.10% – 0.25% over 2-year vest, 3-month cliff
+- **Use case:** Higher-profile advisor (state medical director, well-known academic). Negotiate up from honorarium if advisor asks.
+- **Structure:** Standard FAST advisor agreement (Founder Institute template).
+
+### Renegotiation Trigger (after 6 months)
+
+Re-evaluate based on:
+- Is advisor actively reviewing quarterly?
+- Has the letter opened agency deals?
+- Is advisor open to a second 6-month renewal?
+
+If valuable and renewing → offer equity grant in addition to reduced honorarium ($250/month + 0.10% equity).
+
+---
+
+## Outreach Sequence
+
+**Step 1 — Warm intro.** Tanner requests intro via LACoFD contact (captain, chief, or union rep). Goal: single-sentence email from the referrer to the MD with Tanner cc'd.
+
+**Step 2 — Brief follow-up email** (within 24 hours of intro). Pattern:
+- Single paragraph: who PG is, one concrete win (e.g., "1,800 field medics use it weekly across Southern California"), the ask (30-minute demo call).
+- Link to a 2-minute Loom demo video.
+- No attachments. No deck on first touch.
+
+**Step 3 — 30-minute demo call.** Tanner walks the MD through:
+1. Live protocol lookup on phone (30 sec)
+2. Confidence score + citation flow (2 min)
+3. Agency admin panel — how QA flagging works (3 min)
+4. Downvote review workflow — what the MD would see quarterly (2 min)
+5. Discussion + questions (remaining time)
+
+**Step 4 — Engagement letter.** Send within 24 hours of call. DocuSign, single page, countersigned by Tanner. Start honorarium on first of next month.
+
+---
+

+
+**Status:** Stub — needs medical director review before publish.
+**Target keyword:** `LA County Ref 814`
+**Secondary keywords:** determination of death field, DOA prehospital criteria, LA County paramedic reference
+**Audience:** LA County-area paramedics, EMTs, and firefighter-medics.
+**Meta description (155 chars):** "LA County Ref 814 sets the criteria for Determination of Death in the Field. Here's what paramedics and EMTs need to know and when it applies on scene."
+**Schema.org markup:** `MedicalWebPage` + `MedicalGuideline` (reference, not prescriptive).
+**Publish target:** `protocol-guide.com/blog/la-county-ref-814-explained`
+**CTA url:** `protocol-guide.com/app`
+
+---
+
+## MD Review Gates (clear before publish)
+
+1. Confirm current LA County Ref 814 revision year and any 2026 amendments.
+2. Verify the criteria summary below is consistent with current county standing orders.
+3. Confirm EMT vs paramedic scope statements per Title 22 § 100063 and § 100145.
+4. Flag any language that implies clinical endorsement — keep the piece educational.
+5. Confirm hyperlinks to the current LA County EMS Agency policy PDF.
+
+---
+
+## H1: LA County Ref 814 Explained: Determination of Death in the Field
+
+## H2: What Ref 814 Is
+
+Ref 814 is the Los Angeles County EMS Agency policy that governs when prehospital providers may pronounce or determine death in the field without transporting the patient. It is one of a paramedic's most consequential calls — legally, clinically, and for the family on scene.
+
+The policy exists because not every cardiac arrest is a resuscitation candidate. Some patients arrive with signs incompatible with life, and transporting those patients ties up resources, exposes the crew to risk, and delays closure for the family.
+
+## H2: Who Can Apply Ref 814
+
+**[MD REVIEW — confirm scope statements are accurate.]**
+
+Both EMTs and paramedics may apply Ref 814 when the criteria are unambiguously met. The policy is structured so that line-of-sight signs of irreversible death (for example, decomposition) do not require a paramedic on scene. However, paramedics carry the cardiac monitor required for the asystole-confirmation pathway that triggers withholding resuscitation in the absence of obvious signs.
+
+Practical translation:
+- **EMT-only crew** — can pronounce when one of the absolute obvious-signs criteria is met (rigor, lividity, decomposition, injury clearly incompatible with life).
+- **Paramedic crew** — can pronounce when obvious signs are met OR when the patient is in asystole confirmed by monitor in two leads with the applicable protocol followed.
+
+## H2: The Criteria at a Glance
+
+**[MD REVIEW — the list below is a reference-level summary, not a verbatim copy of the policy. Do not quote-for-quote without written permission. Confirm the summary matches current Ref 814 language.]**
+
+Absolute signs (any one supports determination without resuscitation):
+- Decomposition.
+- Rigor mortis (generalized, not focal).
+- Dependent lividity.
+- Decapitation, incineration, or injury clearly incompatible with life.
+
+Asystole pathway (paramedic with monitor, in absence of absolute signs):
+- Asystole confirmed in two leads.
+- No indications to override (hypothermia, drowning with down-time uncertainty, toxicologic cause in young patient — see current policy for full exclusion list).
+- Appropriate duration of resuscitation attempted and documented if applicable.
+
+## H2: Common Gotchas
+
+### Gotcha 1 — Rigor mimics
+Jaw stiffness from trismus or post-mortem generalized rigor can be confused. Generalized rigor spreading beyond the jaw is the documented sign; focal rigor is not enough.
+
+### Gotcha 2 — Lividity position dependence
+Lividity only appears in dependent areas. A supine patient may show posterior lividity; a prone patient shows it anteriorly. Patients moved after death may have non-dependent lividity, which changes interpretation. Document scene position.
+
+### Gotcha 3 — Hypothermia exclusion
+"Nobody is dead until they are warm and dead" is the classic teaching. Hypothermic cardiac arrest is an explicit exclusion in most determination-of-death policies including Ref 814 [MD REVIEW]. If core temperature is low or unknown-but-plausibly-low (ice rescue, exposure), transport and resuscitate.
+
+### Gotcha 4 — Pediatric patients
+Policy language around pediatrics is generally stricter. Confirm current Ref 814 for any pediatric-specific criteria. When in doubt, transport.
+
+### Gotcha 5 — Legal paperwork
+Ref 814 is not just clinical — it triggers paperwork. Coroner notification, PCR documentation of criteria, and law-enforcement coordination are required. A call that ends at Ref 814 on scene still generates a detailed report.
+
+## H2: How Protocol Guide Helps
+
+**[Non-commercial framing — keep the clinical tone primary.]**
+
+Protocol Guide surfaces Ref 814 with voice search or plain text. Ask "Ref 814 criteria" and the app returns the agency-authored summary, with a link to the current policy PDF. Pediatric asides, exclusion list, and documentation requirements are all one scroll away.
+
+The app is jurisdiction-scoped, so paramedics in LA County see LA County Ref 814, paramedics in a neighboring county see their own policy. No cross-jurisdiction confusion.
+
+## H2: Field Checklist (not a substitute for the policy)
+
+When approaching a potential determination-of-death call:
+
+1. Secure the scene and protect the crew.
+2. Confirm the patient's identity and position.
+3. Assess for absolute signs of death. Document what you see in concrete terms.
+4. If no absolute signs, run the applicable resuscitation protocol.
+5. If asystole persists and the policy criteria are met, apply Ref 814 per current guidance.
+6. Notify base/coroner per LA County procedure.
+7. Support the family. Request law enforcement if needed.
+8. Document the criteria used and timestamps.
+
+## H2: Source and Further Reading
+
+- Los Angeles County EMS Agency policy manual — Ref 814 (current revision). [MD REVIEW — confirm link and revision year.]
+- California Health and Safety Code § 7180 (Uniform Determination of Death Act adoption).
+- Title 22 § 100063 — EMT scope of practice.
+- Title 22 § 100145 — Paramedic scope of practice.

+# EMT vs Paramedic in California: What Each License Can and Cannot Do
+
+**Status:** Stub — needs medical director review before publish.
+**Target keyword:** `EMT vs paramedic California`
+**Secondary keywords:** Title 22 EMS scope, paramedic scope of practice California, EMT scope of practice, California EMS license levels
+**Audience:** EMS students, new-hires, cross-border providers, academy instructors, and anyone writing an onboarding SOP.
+**Meta description (155 chars):** "California EMT and paramedic scope under Title 22 — what each license can and cannot do on scene, with a side-by-side table and common-medication scope cheatsheet."
+**Schema.org markup:** `MedicalWebPage` + `EducationalOccupationalProgram` (reference).

+
+## MD Review Gates (clear before publish)
+
+1. Confirm scope statements are consistent with current Title 22 CCR §§ 100063 (EMT) and 100145 (Paramedic) as amended through 2026.
+2. Confirm the medication table — especially any drug whose scope differs by Local Optional Scope of Practice (LOSOP) expansion.
+3. Verify Advanced EMT (AEMT) row — AEMT is a separate California license level and should be represented if present in target counties.
+4. Flag anything that reads as legal advice; keep reference-level tone.
+5. Confirm all links to the California Code of Regulations and the EMSA website are current.
+
+---
+
+## H1: EMT vs Paramedic in California: What Each License Can and Cannot Do
+
+## H2: Why the Distinction Matters
+
+Every EMS call has someone deciding whether to intubate, push a drug, or call ALS for backup. That decision starts with scope of practice. In California, scope is defined in Title 22 of the California Code of Regulations, administered by the California Emergency Medical Services Authority (EMSA), and then further shaped by each Local EMS Agency (LEMSA) through optional scope expansions.
+
+A paramedic in LA County can do a procedure that might not be approved in a neighboring county. An EMT can carry medications in some counties they can't in others. This article summarizes the baseline under Title 22, notes where LEMSA variation typically occurs, and gives a side-by-side comparison.
+
+## H2: The Three Main License Levels in California
+
+**[MD REVIEW — confirm AEMT language and usage in the target counties.]**
+
+- **EMT (Emergency Medical Technician)** — Title 22 § 100063. Basic Life Support. Baseline scope across California.
+- **AEMT (Advanced EMT)** — Title 22 § 100080 ff. Adds limited ALS skills such as IV access and select medications. Approval and rollout vary by LEMSA.
+- **Paramedic** — Title 22 § 100145. Full Advanced Life Support. Includes advanced airway, cardiac monitor interpretation, and the broadest drug scope.
+
+There is a separate Mobile Intensive Care Nurse (MICN) role and the physician medical director role. Those are outside the scope of this article.
+
+## H2: Side-by-Side Comparison
+
+**[MD REVIEW — the table below is reference-level, based on baseline Title 22 scope. Confirm rows before publish. LOSOP expansions in your county will modify this.]**
+
+| Skill / Authority | EMT | AEMT | Paramedic |
+|-------------------|-----|------|-----------|
+| Patient assessment | Yes | Yes | Yes |
+| BLS airway (OPA/NPA, BVM) | Yes | Yes | Yes |
+| Supraglottic airway | Yes (most counties) | Yes | Yes |
+| Endotracheal intubation | No | No | Yes |
+| Cricothyrotomy | No | No | Yes (select counties / LOSOP) |
+| IV access | No | Yes | Yes |
+| IO access | No | Varies | Yes |
+| Cardiac monitor interpretation | No | No | Yes |
+| Manual defibrillation | No | No | Yes |
+| AED use | Yes | Yes | Yes |
+| 12-lead acquisition | Often (as driver) | Often | Yes (interpretation) |
+| Assist patient's own meds | Yes | Yes | Yes |
+| Oxygen | Yes | Yes | Yes |
+| Oral glucose | Yes | Yes | Yes |
+| Aspirin (chest pain) | Yes | Yes | Yes |
+| Epinephrine auto-injector | Yes | Yes | Yes |
+| Naloxone IN | Yes (most counties) | Yes | Yes |
+| Albuterol nebulizer | Varies by county | Yes | Yes |
+| IV fluids (saline) | No | Yes | Yes |
+| IV pain management (narcotics) | No | No | Yes |
+| Cardiac medications (epi IV, amiodarone, atropine) | No | No | Yes |
+| Electrical cardioversion | No | No | Yes |
+| External pacing | No | No | Yes |
+| Determination of death (absolute signs) | Yes | Yes | Yes |
+| Determination of death (asystole pathway) | No | No | Yes |
+
+Rows marked "varies" or "most counties" are areas where LEMSA LOSOP approval matters most. Always defer to your county policy.
+
+## H2: How to Tell Which License Level Can Give Which Drug
+
+**[MD REVIEW — confirm the decision rules below reflect current policy.]**
+
+A practical decision rule, in order:
+
+1. **Is the medication in the patient's own possession and is the provider assisting?** If yes, even an EMT may assist with it (epi pen, inhaler, oral nitro with specific criteria).
+2. **Is the medication in the EMT baseline Title 22 list?** Oxygen, oral glucose, aspirin, naloxone IN, epinephrine auto-injector for severe allergic reaction. Yes, EMT may administer.
+3. **Does the LEMSA have an EMT optional scope expansion for this drug?** Check your county policy. Examples vary — some counties approve EMT albuterol, some don't.
+4. **Is the medication in the AEMT list under Title 22 § 100080?** If yes and your county has approved AEMTs, AEMT may administer per county policy.
+5. **Otherwise, paramedic scope.**
+
+The asymmetry matters on scene. An EMT who pushes a drug outside scope is outside their license, regardless of good intent. Document the scope basis for every med given.
+
+## H2: Worked Example — Chest Pain Call
+
+An adult patient with chest pain, BP 140/90, HR 90, awake and oriented.
+
+- EMT crew — oxygen if hypoxic, assist with patient's own nitro (county protocol permitting), aspirin per protocol, rapid transport, ALS intercept.
+- AEMT crew — the above plus IV access and saline per protocol.
+- Paramedic crew — the above plus 12-lead interpretation, STEMI activation, IV analgesics per protocol, cardiac monitor, transport to STEMI-capable facility if indicated.
+
+Every step above must align with the applicable LEMSA policy for that call type.
+
+## H2: Common Gotchas
+
+### Gotcha 1 — "Standing order" vs "base hospital contact"
+Some medications and procedures are standing-order for paramedics in one county and require base-hospital contact in another. Title 22 does not dictate this — your LEMSA does.
+
+### Gotcha 2 — Cross-border EMS
+A paramedic licensed by LA County EMS Agency has accreditation in LA County, not automatic accreditation statewide. Mutual-aid and accreditation reciprocity are county decisions. Don't assume scope carries across the county line.
+
+### Gotcha 3 — AEMT rollout varies
+As of the most recent Title 22 amendment cycle, AEMT is authorized statewide, but not every LEMSA has deployed AEMT staffing. If you transfer counties, confirm the LEMSA's AEMT status. [MD REVIEW — confirm current statewide status.]
+
+### Gotcha 4 — "Optional scope" does not mean optional for the provider
+Once a LEMSA has approved an expanded scope (for example, EMT naloxone IN), providers in that county must carry it per policy. It's not an individual choice.
+
+### Gotcha 5 — Student/trainee scope
+A paramedic intern in field training is functioning under a preceptor's license. They are not an independent paramedic scope until released by the preceptor and the training program. Document the preceptor's name on the PCR.
+
+## H2: Source and Further Reading

+**Audience:** Paramedics and advanced EMTs working pediatric calls, especially in LA County and other Color Code-adoptive jurisdictions.

+
+---
+
+## MD Review Gates (clear before publish)
+
+1. Confirm Color Code Drug Doses reference — current LA County policy number and revision year. Article assumes Ref 1309; verify.
+2. Cross-check every drug name and dose range against current LA County pediatric policy and Broselow-Luten color-band guidance.
+3. Confirm the 2018+ Handtevy comparison is accurate if we mention it; otherwise remove.
+4. Verify the "common pitfalls" list reflects actual field audit findings — flag any item that is anecdotal.
+5. Re-read the disclaimer — pediatric dosing is the single most error-prone category in prehospital care, and language must not read as prescriptive.
+
+---
+
+## H1: Pediatric Weight-Based Dosing in the Field
+
+## H2: Why Pediatric Dosing Is a Different Animal
+
+An adult patient gets 1 mg of epinephrine for cardiac arrest. A pediatric patient gets 0.01 mg/kg. A miscalculation on a 20 kg child can mean a tenfold dose error. Stress, low light, family screaming, and a crew working in the back of a moving ambulance all magnify that risk.
+
+That is why pediatric dosing in EMS has moved away from on-the-fly arithmetic toward pre-calculated, visually-anchored reference systems — the Broselow-Luten tape and its color-code dosing partners.
+
+## H2: The Broselow-Luten Tape at a Glance
+
+The Broselow-Luten emergency tape is a length-based resuscitation tape introduced in the 1980s and refined across multiple editions. The principle: length correlates with median weight within a narrow age range. Measure the child from crown to heel and read off the color zone.
+
+Each color zone carries:
+- An estimated weight range.
+- Pre-calculated drug doses for critical medications.
+- Equipment sizes (ETT, BVM, suction catheter, NG tube).
+- Defibrillation energies in joules.
+
+The tape does not replace clinical judgment. A chronically underweight child or an obese child can read one zone lower or higher than their chronologic age would suggest — but the tape is still measuring length, and length-based dosing is validated as safer than weight-guessed dosing under stress.
+
+## H2: Color Code Drug Doses and LA County Ref 1309
+
+**[MD REVIEW — confirm Ref 1309 is the current LA County policy number for Color Code Drug Doses, or adjust.]**
+
+Several counties — LA County included — publish their own color-coded pediatric drug dose charts aligned to the Broselow colors. LA County's chart lives under Reference 1309, Color Code Drug Doses.
+
+Why publish a county version on top of a commercial tape?
+
+1. **Agency-specific formulary.** County formulary may not match the tape's pre-printed doses drug-for-drug.
+2. **Route differences.** IN naloxone, IO access, and IM epinephrine doses vary by agency guidance.
+3. **Scope-of-practice alignment.** Some drugs on commercial tapes are not in LA County paramedic scope; the county chart suppresses those.
+4. **Version control.** Commercial tapes are updated on vendor schedules. County policy updates whenever medical direction changes. A county-published chart is the source of truth for the county.
+
+In the field, the practical workflow is:
+1. Measure the child.
+2. Read the color.
+3. Confirm against the county Color Code chart (printed, tablet, or in Protocol Guide).
+4. Draw up the dose.
+5. Have a second provider verify before administration when feasible.
+
+## H2: Common Pitfalls
+
+### Pitfall 1 — Using the tape upside down
+The tape has a head-end marker. Measuring from foot to head gives the wrong color band. This is the most common rookie error.
+
+### Pitfall 2 — Guessing weight when the tape is available
+"The kid looks about 20 kilos" sounds reasonable and is wrong roughly a third of the time under stress. The tape is present for a reason; use it.
+
+### Pitfall 3 — Volume errors on epinephrine
+Epinephrine for pediatric arrest is 0.01 mg/kg of 0.1 mg/mL (cardiac strength). Pulling the wrong concentration vial — 1 mg/mL instead of 0.1 mg/mL — causes a tenfold overdose. Clear labeling, two-person verification, and following the color chart mitigate this.
+
+### Pitfall 4 — Maximum dose caps
+Some pediatric doses cap at the adult dose. For example, adenosine dosing caps at 6 mg first dose, 12 mg repeat, even for larger adolescents. A strict mg/kg read without checking the cap produces an adult-exceeding dose.
+
+### Pitfall 5 — Defibrillation energy confusion
+Pediatric defib starts at 2 J/kg, then 4 J/kg, then 4-10 J/kg per guidance. Some crews default to adult-style 200 J or biphasic-equivalent, which is outside the pediatric range. The color chart shows the joules by zone.
+
+### Pitfall 6 — Missing the "teal" or "grey" zones
+Some tapes include a grey (newborn) zone and a teal zone for the largest pediatric range. Crews sometimes skip straight to "white" (adult) for a near-adult adolescent. Weight-based for pediatrics runs to ~40 kg before switching to adult dosing per most policies — check your county.
+
+### Pitfall 7 — Not re-verifying across shift change
+If a pediatric patient is held for monitoring and crews swap, the incoming crew should verify the tape zone and weight independently. Hand-off errors compound.
+
+### Pitfall 8 — Oral vs parenteral same-name confusion
+Diazepam PO, IV, and PR are not the same dose. Midazolam IM, IV, IN are different. The tape simplifies but doesn't remove this risk — always confirm the route and the concentration drawn.
+
+## H2: Worked Example — Pediatric Seizure
+
+A 4-year-old with active generalized seizure for 8 minutes. Tape measures yellow zone.
+
+**[MD REVIEW — confirm dose values align with current county pediatric status-epilepticus guidance. Values below are illustrative and must be verified.]**
+
+1. Confirm color zone — yellow.
+2. Protect airway, apply oxygen, suction as needed.
+3. Check the Color Code chart for first-line benzodiazepine:
+ - Midazolam IN — value per chart.
+ - Midazolam IM — value per chart.
+ - Midazolam IV/IO — value per chart.
+4. Administer per route available. Re-dose per policy if seizure persists.
+5. Re-check glucose. Treat hypoglycemia per color chart.
+6. Transport with cardiac monitor, document times.
+7. Notify receiving facility of meds given, routes, and times.
+
+The article deliberately does not print drug dose values. These must come from the live LA County Color Code chart, not a blog post. Protocol Guide surfaces them when the app is opened to the applicable zone.
+
+## H2: How Protocol Guide Helps
+
+Protocol Guide integrates Color Code lookups with voice or text search. Ask "pediatric seizure yellow zone" and the app returns the agency's chart row — with source citation to Ref 1309 — in under 2 seconds. Always verify with the printed tape on your rig and your medical director's guidance.
+
+On scope: weight-based pediatric dosing is paramedic-level in California. EMTs assist with oxygen, positioning, and transport. AEMT programs in approving counties expand this slightly. See the companion article "EMT vs Paramedic in California" for the scope table.
+
+## H2: Field Checklist
+
+Before every pediatric drug push:
+1. Confirm tape zone by measurement.
+2. Confirm the drug name, concentration, and route in the chart.
+3. Verify the calculated dose does not exceed the maximum cap.
+4. Draw up and label the syringe.
+5. Second-provider verification if staffing allows.
+6. Administer.
+7. Document the zone, the dose, the time, and the two providers involved.
+
+## H2: Source and Further Reading

+# LA County Ref 814 Explained: Determination of Death in the Field for EMS
+
+LA County Reference 814 is the Los Angeles County EMS Agency policy that tells a paramedic or EMT when a patient who is not going to be resuscitated can be left on scene rather than transported. It is one of the most consequential decisions a prehospital provider can make — for the patient's family, for the crew's legal standing, and for the rest of the call volume in the system.
+
+This article is an educational walkthrough of how Ref 814 is structured, who can apply it, and where crews most often stumble. It is a paraphrased reference, not a substitute for the live LA County EMS Agency policy document or your medical director's guidance. Every clinical claim is cited; every specific criterion must still be verified against the current policy PDF before you rely on it on scene.
+
+If you want the current version in your pocket for an active call, jump straight to the [Protocol Guide app](https://protocol-guide.com/app), which surfaces Ref 814 with voice search and always links back to the source policy.
+
+## What Ref 814 Governs
+
+Ref 814 is a local policy published by the LA County Emergency Medical Services Agency (LA County EMS Agency, 2024). It sets the circumstances under which prehospital personnel may determine that death has occurred and withhold or terminate resuscitation in the field — without transporting the patient to a receiving facility.
+
+The policy exists because not every cardiac arrest, and not every apneic-pulseless patient, is a resuscitation candidate. Some patients present with signs incompatible with life. Transporting those patients ties up an ALS unit, risks the crew with lights-and-siren driving, and delays the family's ability to begin grief and the coroner's ability to begin investigation (National Association of EMS Physicians [NAEMSP], 2013).
+
+Ref 814 sits alongside the California Health and Safety Code § 7180 adoption of the Uniform Determination of Death Act, which defines death at the state level (Cal. Health & Safety Code § 7180, 1982). Ref 814 is the operational translation of that legal definition for prehospital providers in Los Angeles County.
+
+## Who Can Apply Ref 814
+
+Both EMTs and paramedics can apply Ref 814 — but not identically. Scope is the key variable.
+
+California Title 22 § 100063 authorizes EMTs to recognize obvious signs of death (CA Code Regs. tit. 22 § 100063). California Title 22 § 100145 authorizes paramedics to interpret cardiac rhythms, which opens the monitor-based pathway (CA Code Regs. tit. 22 § 100145).
+
+Practically, this translates to two distinct pathways on scene:
+
+1. **Obvious-signs pathway** — Available to any certified EMS provider, EMT or paramedic, when unambiguous physical findings are present. No cardiac monitor required.
+2. **Asystole-confirmation pathway** — Available only to paramedic-level crews with an ALS monitor, applied in the absence of obvious signs when resuscitation is otherwise not indicated per current policy.
+
+When in doubt about scope, default to resuscitating and transporting. Ref 814 is permissive, not prescriptive — it gives crews the option to determine death, not an obligation to do so.
+
+## The Eleven Circumstances, Paraphrased by Category
+
+Ref 814 enumerates eleven distinct circumstances under which determination of death in the field is appropriate. Rather than reproduce the list verbatim (which would be a copyright concern and a fast path to being out-of-date the moment the county revises the policy), this article groups the circumstances into three functional categories.
+
+### 1. Traumatic Circumstances
+
+This category covers injuries where survival is physically impossible regardless of intervention. Clinical examples include decapitation, incineration, evisceration of the heart or brain, and decomposition that can only occur post-mortem. The governing principle is that no combination of airway, circulation, or drug therapy available in the field or at a receiving facility could restore perfusion.
+
+Documentation requirement: describe the finding in objective, concrete terms on the Patient Care Report (PCR). "Decapitation" is a finding; "unsurvivable injury" is a conclusion and should be supported by specifics.
+
+### 2. Medical Circumstances with Objective Post-Mortem Findings
+
+This category covers patients who present with physical signs that develop only after death:
+
+- Generalized rigor mortis.
+- Dependent lividity consistent with the patient's position.
+- Early decomposition.
+
+The clinical basis is well-established in the post-mortem physiology literature (DiMaio & DiMaio, 2001). Rigor typically becomes appreciable within 2-6 hours post-mortem, and lividity begins within 30 minutes but fixes around 8-12 hours. These findings make return of spontaneous circulation impossible — the tissue has already undergone irreversible changes.
+
+The gotcha: lividity must be dependent. A patient moved after death may show non-dependent lividity, which changes interpretation. Document scene position and any movement by bystanders or first responders prior to your arrival.
+
+### 3. Resuscitation-Contraindicated Circumstances (Asystole Pathway)
+
+This category covers patients in cardiac arrest who do not have obvious signs of death but meet criteria that make resuscitation inappropriate. Typical elements of this pathway include:
+
+1. Confirmed asystole in at least two ECG leads.
+2. A downtime exceeding the policy-specified threshold (verify current Ref 814).
+3. Absence of any reversible cause that would extend the resuscitation window — notably hypothermia, drowning with uncertain submersion time, pediatric arrest, or suspected toxicologic cause in a young patient.
+4. Appropriate duration of high-quality resuscitation attempted and documented, per the American Heart Association's Advanced Cardiovascular Life Support guidelines (AHA, 2020).
+
+The asystole pathway is the part of Ref 814 that most commonly generates medical-director review. Document every element.
+
+## Decision Tree for Field Use
+
+The following decision tree condenses Ref 814 into a scannable flow. It is a teaching aid, not a substitute for the policy itself.
+
+1. **Is the scene safe? Is the crew safe?** If no, secure the scene before any patient contact.
+2. **Are any traumatic or post-mortem signs present on first assessment?** Decapitation, incineration, evisceration, generalized rigor, dependent lividity, decomposition.
+ - If yes → obvious-signs pathway. Document findings, notify coroner per policy, support family.
+ - If no → continue to step 3.
+3. **Is the patient in cardiac arrest?**
+ - If no → treat and transport per applicable protocol.
+ - If yes → continue to step 4.
+4. **Are there any reversible-cause indicators that preclude determination?** Hypothermia, drowning with unclear timing, pediatric presentation, toxicologic cause, penetrating trauma with short transport time.
+ - If yes → resuscitate and transport per applicable protocol.
+ - If no → continue to step 5.
+5. **Is asystole confirmed in at least two leads, with policy-specified downtime, after appropriate resuscitation?**
+ - If yes → paramedic may apply the asystole pathway per current Ref 814.
+ - If no → continue resuscitation or transport per protocol.
+6. **Document everything.** Criteria used, timestamps, monitor strips, scene findings, coroner notification.
+
+## Common Gotchas
+
+Five areas account for most crew errors and most medical-director callbacks on Ref 814 calls.
+
+### Gotcha 1: Focal Rigor Is Not Generalized Rigor
+
+Jaw stiffness from trismus (for example, in organophosphate poisoning or tetanus) can mimic early rigor mortis (Perper, 2006). The policy asks for generalized rigor — rigor that extends beyond the jaw and involves the extremities. Focal rigor alone does not support determination.
+
+### Gotcha 2: Lividity Is Position-Dependent
+
+A supine patient shows posterior lividity; a prone patient, anterior. A patient who was moved may show non-dependent lividity, which either means the patient was moved post-mortem or the finding is not actually lividity (DiMaio & DiMaio, 2001). Always document scene position and any witnessed or reported movement.
+
+### Gotcha 3: Hypothermia Is an Explicit Exclusion
+
+"Nobody is dead until they are warm and dead" remains the prehospital teaching for a reason (Brown et al., 2012). Hypothermic cardiac arrest can mimic brain death in the field, but some hypothermic arrests recover with prolonged resuscitation and rewarming. If core temperature is low, unknown, or plausibly low based on environment (ice water, cold exposure), transport and resuscitate — do not apply Ref 814.
+
+### Gotcha 4: Pediatrics Require a Higher Threshold
+
+Pediatric determination-of-death policy language is typically stricter than adult language (American Academy of Pediatrics [AAP] & American College of Emergency Physicians [ACEP], 2014). The emotional and legal weight of pediatric scene pronouncements pushes most systems toward transport unless the traumatic or post-mortem findings are unambiguous. Verify current Ref 814 pediatric carve-outs before relying on the adult criteria for a child.
+
+### Gotcha 5: The Paperwork Is the Policy
+
+A determination-of-death call is not "the one where you did less." It requires coroner notification, law-enforcement coordination, a detailed PCR documenting every criterion used, and often base-hospital contact (NAEMSP, 2013). A perfect clinical call with incomplete documentation is a QA event.

+The app is jurisdiction-scoped by design. Paramedics in LA County see LA County's Ref 814; providers in Ventura, San Bernardino, or Kern see their county's equivalent policy. Cross-border confusion is engineered out.
+
+## Frequently Asked Questions
+
+### Can an EMT alone apply Ref 814?
+
+Yes, for the obvious-signs pathway. An EMT may determine death based on unambiguous physical findings (decapitation, decomposition, generalized rigor, dependent lividity). The asystole pathway requires a cardiac monitor and paramedic scope (CA Code Regs. tit. 22 § 100063; LA County EMS Agency, 2024). Verify your agency's current training and local policy guidance before relying on EMT-alone determination.
+
+### Does Ref 814 apply outside LA County?
+
+No. Ref 814 is an LA County-specific reference number. Every California LEMSA publishes its own determination-of-death policy — the clinical principles are similar but numbering, criteria wording, and pediatric thresholds vary. Check your LEMSA's policy manual for the equivalent.
+
+### What if the family refuses to accept the determination?
+
+Stay on scene, provide emotional support, request law-enforcement presence if needed, and follow your county's coroner notification procedure. Clinical determination is the paramedic's call; family conflict is a social-emotional and legal matter handled per agency policy (NAEMSP, 2013). Do not reverse a clinically-sound determination because the family objects — document the objection and proceed per policy.
+
+### How do I document an asystole-pathway Ref 814 call?
+
+Minimum elements to document: time of arrival, findings on initial assessment, rhythm strips showing asystole in two leads, total downtime, interventions attempted and durations, reversible causes considered and excluded, time of determination, coroner notification time and case number, and law-enforcement interaction. Print and attach monitor strips to the PCR when your system supports it.
+
+### Can I resume resuscitation after applying Ref 814?
+
+Generally no. Once the determination is made and documented, the patient is legally deceased. If new information emerges before the coroner takes custody that would change the decision (for example, previously-unknown hypothermia), contact base hospital for guidance. This is rare and should be the exception, not the rule.
+
+## The Bottom Line
+
+Ref 814 is designed to be applied with clinical confidence, not invented on the fly. Learn the three categories, know the five common gotchas, document like a plaintiff's attorney is reading your PCR, and defer to transport when anything is ambiguous. The policy is permissive — it lets you stop resuscitation when the criteria are clearly met. Nothing in Ref 814 ever forces that call.

+# EMT vs Paramedic in California: Scope of Practice Under Title 22
+
+California has four distinct prehospital clinical-provider scopes — EMT, AEMT, Paramedic (including Limited Advanced Life Support variants), and the Mobile Intensive Care Nurse (MICN) — and every ambulance call in the state is shaped by which of these licenses is on scene and which Local EMS Agency (LEMSA) is the licensing authority. This article lays out the side-by-side scope under Title 22 California Code of Regulations Division 9, notes where local optional scope (LOSOP) expansions typically diverge, and flags the gotchas that catch cross-county hires and new graduates.
+
+Any scope question that affects an active patient should be answered by your agency's current policy manual, not a blog post. For the 2-second field lookup, [Protocol Guide](https://protocol-guide.com/app) scopes every answer to your agency and license level.
+
+## Why the EMT-vs-Paramedic Distinction Drives Every Call
+
+Every EMS call has a moment where someone decides whether to intubate, push a drug, or call for ALS backup. That decision starts with scope. In California, scope of practice is defined in Title 22 of the California Code of Regulations, Division 9, and administered by the California Emergency Medical Services Authority (EMSA) (California EMSA, 2024). Each of the 33 Local EMS Agencies then refines that baseline scope through locally-approved optional expansions (CA Health & Safety Code § 1797.220).
+
+The result: a paramedic credentialed in LA County may legally perform a procedure that is not approved in Ventura County, even though both work under the same Title 22. An EMT in one county may carry naloxone while an EMT in an adjacent county does not. This is not a bug; it is the California EMS governance model by design. Knowing the base Title 22 scope and then knowing your LEMSA's overlay is non-negotiable.
+
+## The Four California EMS Provider Levels
+
+California recognizes four clinical-provider levels relevant to prehospital scope:
+
+1. **EMT (Emergency Medical Technician)** — Title 22 § 100063 et seq. Basic Life Support (BLS) baseline, uniform across the state (CA Code Regs. tit. 22 § 100063).
+2. **AEMT (Advanced EMT)** — Title 22 § 100080 et seq. Limited ALS skills such as IV access, limited IV medications, and blood glucose testing. Deployment varies by LEMSA (CA Code Regs. tit. 22 § 100080).
+3. **Paramedic** — Title 22 § 100145 et seq. Full Advanced Life Support (ALS), including advanced airway, cardiac monitoring and interpretation, and the broadest drug formulary (CA Code Regs. tit. 22 § 100145). Some agencies operate a Limited Advanced Life Support (LALS) variant where paramedics work without full scope in specific response models.
+4. **MICN (Mobile Intensive Care Nurse)** — RN with EMSA-approved MICN authorization, operating primarily as base-hospital medical control under paramedic radio contact (CA Code Regs. tit. 22 § 100165).
+
+Physician medical direction sits above this stack but is outside the prehospital clinical-provider category — medical directors write the standing orders; they are not on the rig.
+
+## Side-by-Side Scope Comparison: BLS vs ALS vs LALS vs MICN
+
+The following table is a reference-level snapshot of the baseline Title 22 scope. Rows marked *varies* are where LEMSA optional scope commonly diverges. The MICN column reflects base-hospital contact authority, not field presence.
+
+| Skill / Authority | EMT (BLS) | AEMT (LALS-adjacent) | Paramedic (ALS) | MICN (base-hospital) |
+|---|---|---|---|---|
+| Patient assessment | Yes | Yes | Yes | N/A (not on scene) |
+| OPA / NPA / BVM | Yes | Yes | Yes | Orders only |
+| Supraglottic airway | Yes (most counties) | Yes | Yes | Orders only |
+| Endotracheal intubation | No | No | Yes | Orders only |
+| Cricothyrotomy | No | No | Yes (LOSOP) | Orders only |
+| AED | Yes | Yes | Yes | Orders only |
+| Manual defibrillation | No | No | Yes | Orders only |
+| Cardiac monitor interpretation | No | No | Yes | Orders / confirmation |
+| 12-lead ECG acquisition | Often | Often | Yes (interpretation) | Orders |
+| Electrical cardioversion | No | No | Yes | Orders only |
+| External pacing | No | No | Yes | Orders only |
+| IV access | No | Yes | Yes | Orders only |
+| IO access | No | Varies | Yes | Orders only |
+| IV fluids (normal saline) | No | Yes | Yes | Orders only |
+| Oxygen | Yes | Yes | Yes | Orders |
+| Oral glucose | Yes | Yes | Yes | Orders |
+| Aspirin (chest pain) | Yes | Yes | Yes | Orders |
+| Assist patient's own meds | Yes | Yes | Yes | Orders |
+| Epinephrine auto-injector | Yes | Yes | Yes | Orders |
+| Naloxone IN / IM | Yes (most counties) | Yes | Yes | Orders |
+| Albuterol neb | Varies | Yes | Yes | Orders |
+| IV epinephrine / atropine / amiodarone | No | No | Yes | Orders only |
+| IV / IM opioid analgesics | No | No | Yes | Orders only |
+| Benzodiazepines (seizure) | No | Limited (LOSOP) | Yes | Orders only |
+| Determination of death — obvious signs | Yes | Yes | Yes | Confirmation |
+| Determination of death — asystole pathway | No | No | Yes | Confirmation |
+| Base hospital contact | As needed | As needed | As needed | Receives contact |
+| Standing-order authority | BLS only | Limited ALS | Full ALS | Modifies orders |
+
+AEMT is shown in a "LALS-adjacent" column because California LALS programs are implemented at the LEMSA level rather than statewide — some agencies operate AEMT-LALS; others do not deploy AEMTs at all.
+
+## Three Decision Rules for "Who Can Give What"
+
+When a drug question comes up mid-call, these rules in order resolve most situations:
+
+1. **Is the medication the patient's own and are you assisting?** Even EMTs may assist with a patient's personal inhaler, epinephrine auto-injector, or oral nitroglycerin under specified clinical criteria (CA Code Regs. tit. 22 § 100063). Assisting is not administering.
+2. **Is it on the EMT Title 22 baseline list?** Oxygen, oral glucose, aspirin for chest pain, naloxone IN (most counties), and epinephrine auto-injector for severe allergic reaction are EMT-administrable under baseline Title 22.
+3. **Is it in your LEMSA's optional-scope expansion?** County policy may expand EMT or AEMT scope beyond baseline. Example: EMT albuterol administration is county-variable. If the medication is neither baseline nor LOSOP-approved for your license, it is paramedic-only — full stop.
+
+Document the scope basis for every medication administered on the PCR. "Given per LA County EMS Agency Policy Reference X" is the right form.
+
+## Worked Example: Chest Pain at 0230
+
+A 58-year-old male with substernal chest pain, blood pressure 142/88, heart rate 94, alert and oriented. How does scope shape the response?
+
+- **EMT-only BLS crew:** Oxygen titrated to SpO2, assist patient with personal nitroglycerin if county protocol permits, aspirin 324 mg PO per protocol, rapid transport, request ALS intercept.
+- **AEMT crew:** All of the above plus IV access and normal saline per protocol.
+- **Paramedic crew:** All of the above plus 12-lead ECG with interpretation, STEMI activation if indicated, cardiac monitoring, IV analgesia per protocol, transport to STEMI-capable facility per destination policy (AHA, 2020).
+- **Base-hospital MICN:** Receives radio contact, modifies orders as clinically indicated, documents the order modification in the base-hospital record.
+
+Every level above must align with the LEMSA policy for that specific call type. "The paramedic's standing order" in LA County may be "base-hospital contact required" one county north.
+
+## Common Scope Gotchas
+
+### Gotcha 1: Standing Orders vs Base-Hospital Contact
+
+Some medications are standing-order in one county (paramedic gives without calling in) and base-contact in another (paramedic must reach the base hospital first). Title 22 does not dictate this distinction — your LEMSA does. Assume base contact until proven otherwise when working in an unfamiliar county.
+
+### Gotcha 2: Accreditation Does Not Carry Across County Lines
+
+A paramedic with a state license plus LA County accreditation is not automatically accredited in Orange County or Kern (California EMSA, 2024). Mutual-aid deployments have their own reciprocity rules; routine cross-county work requires local accreditation. Check with the receiving LEMSA before accepting a shift.
+
+### Gotcha 3: AEMT Rollout Is Uneven
+
+AEMT is authorized statewide under Title 22 § 100080 et seq., but not every LEMSA deploys AEMTs. Some agencies skip the AEMT tier entirely; others run AEMTs only on specific response types. Confirm your LEMSA's current AEMT deployment status before betting a procedure on the license level.
+
+### Gotcha 4: "Optional" Scope Is Not Optional for the Individual Provider
+
+Once a LEMSA approves an optional scope — say, EMT naloxone IN — every credentialed EMT in that county operates under that expanded scope per policy. It is not a per-provider opt-in. If you refuse the optional scope you may be out of compliance with your agency's operational expectation.
+
+### Gotcha 5: Student and Intern Scope
+
+A paramedic intern in field training operates under the preceptor's license, not an independent paramedic scope, until the training program and preceptor both release the intern (CA Code Regs. tit. 22 § 100145). Document the preceptor name on every PCR during internship. The same applies to EMT academy students in field rotations.
+
+### Gotcha 6: LALS and Limited-Scope Paramedic Programs
+
+Some LEMSAs run LALS or limited-scope paramedic programs with a narrower formulary than full ALS. Do not assume your paramedic card grants you full ALS scope in every California county — the LALS model exists precisely to scope-limit in specific systems.
+
+## Where the Scope Question Shows Up Most Often
+
+From a workflow perspective, the recurring scope question on shift is never "what is the Title 22 baseline?" — it is "can I give this drug, right now, on this call, in this county, with this license?" That is a four-variable question, and it is the entire reason Protocol Guide scopes every answer by agency and license: [open the app](https://protocol-guide.com/app) and the drug screen tells you the scope basis alongside the dose.
+
+## Frequently Asked Questions
+
+### What is the fastest way to know if I can give a drug in my county?
+
+Confirm four variables in order: license level (EMT / AEMT / Paramedic), LEMSA (which county are you operating in?), call type (some scope applies only to specific presentations), and policy reference (standing order vs base contact). If any variable is uncertain, call your supervisor or base hospital before administration.
+
+### Is an EMT allowed to give naloxone in California?
+
+Baseline Title 22 § 100063 permits EMT administration of naloxone intranasal for suspected opioid overdose in most counties, but LEMSA policy governs specific indications, dosing, and documentation. Most California LEMSAs have implemented EMT naloxone IN since the 2015 statewide authorization cycle, but verify your county's current policy before assuming authorization (California EMSA, 2024).
+
+### Can a paramedic perform a cricothyrotomy in every county?
+
+No. Surgical cricothyrotomy is a LOSOP-expansion scope for paramedics in California — some LEMSAs authorize it; others do not (California EMSA, 2024). Needle cricothyrotomy authorization also varies. Confirm your county's current airway-rescue policy before assuming the procedure is in-scope.
+
+### What does LALS mean?
+
+LALS stands for Limited Advanced Life Support. It is a California LEMSA-level program where paramedics (or AEMTs in some models) operate with a restricted formulary and procedure list compared to full ALS (California EMSA, 2024). LALS exists in rural and volunteer-heavy systems where full ALS staffing is impractical.
+
+### How often does Title 22 change?
+
+EMSA revises Title 22 Division 9 periodically — major revisions occur every few years, with minor clarifications more frequently (California EMSA, 2024). Treat any Title 22 scope claim as time-stamped; verify the current revision before relying on specific scope language. The EMSA website publishes the current text.
+
+## The Bottom Line
+
+California scope is defined in Title 22, refined by each LEMSA, and shaped on scene by license level, call type, and specific policy reference. The EMT-vs-paramedic question is rarely binary — it is a matrix, and the answer changes at the county line. Use the table above as a starting point, not a final answer.
+
+When a scope question is live on a call, use a tool that already knows your license and agency. [Protocol Guide](https://protocol-guide.com/app) is built for that exact question.

+# Pediatric Weight-Based Dosing in EMS: Broselow, APLS, and Field Safety
+
+Pediatric weight-based dosing is the single most error-prone category in prehospital medicine (Lammers et al., 2014). A tenfold concentration mistake on a 20 kg child at 0300, in the back of a moving ambulance, with a family screaming in the doorway, is the nightmare scenario every paramedic trains to avoid. The field answer has moved decisively away from on-the-fly arithmetic toward pre-calculated, visually-anchored reference systems — the length-based Broselow-Luten tape, age-based APLS formulas, and county-specific color-code charts like LA County Reference 1309.
+
+This article walks through the three main estimation methods, the safety pitfalls that keep showing up in EMS error-reporting data, and the workflow a crew should run before every pediatric drug push. It is educational. Do not draw a drug dose from this page — draw from your county's current Color Code chart, your measured Broselow zone, or your medical director's standing orders. If you want those surfaced in 2 seconds on scene, [Protocol Guide](https://protocol-guide.com/app) has your county's pediatric chart built in.
+
+## Why Pediatric Dosing Is a Different Animal
+
+An adult in cardiac arrest gets 1 mg of epinephrine. A pediatric patient in cardiac arrest gets 0.01 mg/kg of the 0.1 mg/mL cardiac-strength concentration (AHA, 2020). On a 10 kg child that is 0.1 mg, or 1 mL drawn from the correct vial. Pull the 1 mg/mL epinephrine vial instead and push 1 mL — that is a tenfold overdose, a known error pathway in prehospital care (Lammers et al., 2014; Porter et al., 2020).
+
+The physiology compounds the risk. Pediatric patients have smaller margins for hemodynamic error, faster deterioration in hypoxia, and drug volumes of distribution that differ from adult pharmacokinetics (Lavonas et al., 2020). A dose error that an adult patient tolerates may cause acute clinical harm in a child.
+
+The field answer to this risk is not "do math more carefully." It is "remove the math from the critical path." Pre-calculated length-based and age-based tools exist precisely for this reason.
+
+## Three Weight-Estimation Methods EMS Uses
+
+Three methods account for the vast majority of prehospital pediatric weight estimation.
+
+### 1. Length-Based Estimation — Broselow-Luten Tape
+
+The Broselow-Luten emergency tape is the most-studied length-based resuscitation tool in prehospital medicine (Luten et al., 1992). The principle: a child's length correlates closely with median weight within narrow age ranges. Measure from crown to heel while the patient is supine, read the color zone that corresponds to the heel position, and every drug dose, ETT size, defibrillation energy, and equipment choice is pre-calculated for that zone.
+
+Each color zone on a current-edition tape includes:
+
+1. Estimated weight range for the zone.
+2. Pre-calculated drug doses for critical resuscitation medications (epinephrine, atropine, amiodarone, adenosine, midazolam, naloxone).
+3. Equipment sizing (endotracheal tube, laryngoscope blade, bag-valve-mask size, suction catheter, NG tube).
+4. Defibrillation and cardioversion energies in joules.
+
+The tape does not replace clinical judgment. A chronically underweight or obese child may read one zone off their chronologic age — but the tape measures actual length, which remains the best field proxy for actual weight under stress (Sinha et al., 2012).
+
+### 2. Age-Based Estimation — APLS and Related Formulas
+
+When a tape is unavailable or the child exceeds tape range, age-based formulas from Advanced Paediatric Life Support (APLS) and similar curricula give a fallback estimate (Advanced Life Support Group [ALSG], 2016):
+
+- **Infants 0-12 months:** Weight (kg) ≈ (age in months + 9) / 2.
+- **Children 1-5 years:** Weight (kg) ≈ (2 × age) + 8.
+- **Children 6-12 years:** Weight (kg) ≈ (3 × age) + 7.
+
+Age-based estimates carry more error than length-based measurement — roughly 10-20% greater absolute error in validation studies (Young et al., 2018). Use them when the tape is unavailable, and flag the estimation method in the PCR.
+
+### 3. Color-Code Drug Dose Charts — County-Specific Overlays
+
+Counties that use the Broselow color system (LA County, among others) publish their own color-code drug dose charts aligned to the Broselow zones. LA County publishes this as Reference 1309, Color Code Drug Doses (LA County EMS Agency, 2024).
+
+Why a county chart on top of a commercial tape?
+
+1. **Agency-specific formulary.** County drug formulary may differ drug-for-drug from a commercial tape's preprinted values.
+2. **Route-specific dosing.** Intranasal naloxone, intraosseous access doses, and intramuscular epinephrine concentrations vary by agency.
+3. **Scope-of-practice alignment.** A commercial tape may list medications that are not in the county's paramedic scope; the county chart suppresses those.
+4. **Version control.** Commercial tapes update on vendor schedules. County policy updates whenever medical direction changes. A county chart is the source of truth for providers in that county.
+
+Field workflow: measure, read the zone, confirm the dose against the county chart (printed on the rig, on a tablet, or in Protocol Guide), draw up, verify with a second provider when feasible, administer. Document the zone, the chart version, the calculated dose, and the two providers involved.
+
+## The Eight Field Pitfalls That Cost Seconds or Cause Errors
+
+Error-reporting data and simulation studies consistently surface the same eight pitfalls in pediatric field dosing (Lammers et al., 2014; Porter et al., 2020).
+
+### Pitfall 1: Using the Tape Upside Down
+
+Every Broselow tape has a head-end marker. Measuring from foot-to-head rather than head-to-foot puts the heel on the wrong color band. This is the most common rookie error. Laminate a "HEAD HERE" sticker on your tape's head end if your agency permits.
+
+### Pitfall 2: Guessing Weight When a Tape Is Available
+
+"The kid looks about 20 kilos" is subjectively plausible and objectively wrong roughly a third of the time under stress (Sinha et al., 2012). If a tape is on the rig and the child fits the tape, measure. Do not guess.
+
+### Pitfall 3: Pulling the Wrong Epinephrine Concentration
+
+Pediatric cardiac-arrest epinephrine is 0.01 mg/kg of the 0.1 mg/mL (1:10,000) cardiac-strength solution. The 1 mg/mL (1:1,000) vial is for IM anaphylaxis dosing. Pulling the wrong vial for a cardiac-arrest call is the canonical tenfold-overdose pathway (Porter et al., 2020). Two-person verification, visible vial labeling, and checking the color chart's concentration notation are the documented mitigations.
+
+### Pitfall 4: Ignoring Maximum-Dose Caps
+
+Several pediatric medications cap at the adult dose. Adenosine for SVT is 0.1 mg/kg first dose capped at 6 mg, 0.2 mg/kg second dose capped at 12 mg (AHA, 2020). A straight mg/kg calculation in a large adolescent can exceed the cap — always check the cap before drawing up.
+
+### Pitfall 5: Defibrillation Energy Confusion
+
+Pediatric manual defibrillation starts at 2 J/kg, escalates to 4 J/kg, and may continue at 4-10 J/kg per current AHA guidance (AHA, 2020). A crew reflexively selecting an adult 200 J setting is outside pediatric guidance. The color chart and tape both show pediatric energies by zone.
+
+### Pitfall 6: Skipping the Teal and Grey Zones
+
+Current-edition tapes include a grey (newborn) zone and a teal zone covering the largest pediatric range. Crews sometimes skip straight from a smaller color to "adult" for a near-adult adolescent. Most county policies extend weight-based pediatric dosing to roughly 40 kg before switching to adult dosing (LA County EMS Agency, 2024). Verify your county's threshold.
+
+### Pitfall 7: Handoff Errors at Shift Change
+
+If a pediatric patient is held for transport or observation and crews change, the incoming crew should independently verify the tape zone and the estimated weight. Handoff errors compound when the receiving provider assumes the zone rather than remeasuring.
+
+### Pitfall 8: Route and Form Confusion
+
+Diazepam PO, IV, and PR are different dose regimens. Midazolam IM, IV, and IN have different mg/kg values. The tape simplifies route-specific dosing but does not eliminate the confusion — always confirm the route on the chart, the concentration drawn, and the route of administration documented (ALSG, 2016).
+
+## Worked Example: Pediatric Status Epilepticus
+
+A 4-year-old with an active generalized seizure at 8 minutes' duration. Broselow measurement shows the yellow zone. Crew is a two-paramedic ALS unit in LA County.
+
+1. **Confirm color zone by measurement.** Reverify head-end and heel position.
+2. **Protect airway.** Position, suction as needed, apply oxygen. Monitor SpO2 and ETCO2.
+3. **Check the LA County Ref 1309 Color Code chart for first-line benzodiazepine at the yellow zone.** Doses are chart-specific; do not reconstruct them from memory. Options per LA County policy typically include midazolam IN, midazolam IM, and midazolam IV/IO.
+4. **Administer per available route.** Re-dose per policy if seizure persists beyond the documented interval.
+5. **Re-check blood glucose.** Treat hypoglycemia per pediatric hypoglycemia dosing in the color chart if indicated (AHA, 2020).
+6. **Transport with cardiac monitoring.** Document times, meds, routes, and provider verification.
+7. **Notify receiving facility.** Include medication, dose in mg (not just mg/kg), route, and administration time.
+
+This article deliberately does not print specific drug values. Those must come from your live county chart, not a blog post. The workflow — measure, confirm on chart, verify, administer, document — is the same in every county even when the specific values differ.
+
+## Field Checklist for Every Pediatric Drug Push
+
+Before every pediatric medication administration, run this seven-step check. Crews that run it before every push have lower error rates in simulation studies (Lammers et al., 2014).
+
+1. Confirm the tape zone by measurement, or confirm the age-based estimate if tape is unavailable.
+2. Confirm the drug name, concentration, and route on the county chart.
+3. Verify the calculated dose does not exceed the maximum cap.
+4. Draw up into a labeled syringe.
+5. Second-provider verification when staffing permits (zone, drug, concentration, route, dose).
+6. Administer.
+7. Document zone, drug, concentration, dose, route, time, and both providers on the PCR.
+
+## Where Protocol Guide Fits in Pediatric Workflow
+
+Protocol Guide surfaces your county's color chart with voice or text search, always cited to the source policy reference. Ask "pediatric seizure yellow zone" and the app returns the agency-authored chart row with the current policy link — no scrolling a 200-page PDF on a moving ambulance. [Open Protocol Guide](https://protocol-guide.com/app).
+
+On scope: weight-based pediatric dosing is paramedic-level in California under Title 22 § 100145 (CA Code Regs. tit. 22 § 100145). EMTs support airway, positioning, transport, and glucose checks. AEMT programs in approving counties expand this modestly. For the full EMT-vs-paramedic matrix, see the companion article on [California scope of practice](./02-emt-vs-paramedic-ca-scope.md).
+
+## Frequently Asked Questions
+
+### Is the Broselow tape accurate for obese pediatric patients?
+
+Length-based estimation systematically underestimates weight in obese children because actual weight exceeds the median-for-length on which the tape is built (Sinha et al., 2012). Several modified tapes and adjunct formulas address this; when a child is visibly obese, most systems recommend using the measured zone for ETT sizing and defibrillation, but verifying drug doses with a weight-for-age estimate or guardian-reported weight if available.
+
+### Which is better in the field — Broselow or APLS?
+
+Length-based estimation with the Broselow tape has lower absolute error than age-based APLS formulas in most validation studies (Young et al., 2018). The tape is preferred when available and the child fits the tape range. APLS formulas are an appropriate fallback.
+
+### What is the pediatric weight cutoff for switching to adult dosing?
+
+Most California EMS policies transition from pediatric weight-based dosing to adult dosing at approximately 40 kg, but the exact threshold varies by LEMSA (LA County EMS Agency, 2024). A large adolescent above the tape's upper zone may still receive pediatric calculations in some protocols. Check your county's current policy before the switch.
+
+### What do I document on a pediatric drug administration?
+
+Minimum documentation: tape zone (or estimation method if tape was unavailable), estimated weight, drug name, concentration, calculated dose in mg, route, administration time, response to dose, second-provider verification (if staffing permitted), and the source chart reference (for example, "LA County Ref 1309 current revision"). Simulation studies identify incomplete documentation as a common contributor to subsequent error investigations (Lammers et al., 2014).
+
+### Can I use a smartphone pediatric drug calculator instead of the tape?
+
+Electronic tools are useful adjuncts but not tape replacements in most California systems. The tape is approved equipment; a phone app is an adjunct. Protocol Guide is designed to complement — not replace — your agency's tape and printed color chart.
+
+## The Bottom Line
+
+Pediatric weight-based dosing is safer when arithmetic is removed from the critical path. Measure with the tape, confirm on the county chart, verify with a second provider, administer, document. Know the eight common pitfalls. Never draw a drug dose from a blog post — draw from the current county chart on the rig or in [Protocol Guide](https://protocol-guide.com/app), which keeps your county's chart version-controlled and a voice-query away.

+## Medical Disclaimer
+
+This article is a reference-level overview for continuing education and onboarding. It deliberately omits specific drug dose values because those must come from your agency's current official color chart, Broselow tape, and medical director's standing orders. Pediatric dosing is one of the highest-risk categories in prehospital medicine. Always measure before dosing when the tape is available, verify with a second provider when staffing allows, and follow your medical director's guidance. Not a substitute for clinical judgment.

+# Protocol Guide Long-Form Articles
+
+Source directory for Protocol Guide's educational long-form SEO articles. These are the publishable companions to the drafts in `docs/content/article-stubs/`. Stubs stay as records of the drafting process; this directory holds the polished versions destined for `protocol-guide.com/blog/*`.
+
+## Directory Contents
+
+| File | Primary Keyword | Publish Target | Status |
+|---|---|---|---|
+| `01-la-county-ref-814-explained.md` | `LA County Ref 814` | `protocol-guide.com/blog/la-county-ref-814-explained` | Pending MD review |
+| `02-emt-vs-paramedic-ca-scope.md` | `EMT vs paramedic California` | `protocol-guide.com/blog/emt-vs-paramedic-ca-scope` | Pending MD review |
+| `03-pediatric-weight-based-dosing.md` | `pediatric weight-based dosing` | `protocol-guide.com/blog/pediatric-weight-based-dosing` | Pending MD review |
+
+Every article includes a `MD-REVIEW-REQUIRED` block at the bottom listing clinical claims that must be verified before publish. No article ships without medical director sign-off on that block.
+
+## Publishing Workflow
+
+1. **Draft in stubs.** Drafts live in `docs/content/article-stubs/NN-slug.md` with open MD-review gates.
+2. **Promote to articles.** Polished drafts are written to `docs/content/articles/NN-slug.md`. Frontmatter must include `primaryKeyword`, `secondaryKeywords`, `canonical`, `schemaType`, and `medicalReviewStatus`.
+3. **Medical director review.** MD reads the article and the `MD-REVIEW-REQUIRED` block at the bottom. MD either signs off by changing `medicalReviewStatus: pending` → `reviewed`, adding a `medicalReviewer` field, and deleting the review block, or returns the article with required changes.
+4. **Editorial pass.** Marketing reviews for keyword density (each primary keyword 1-3x in body; do not exceed 3x), internal-link count (2+ links to `/app`), FAQ coverage (3-5 Q&A), and tone (educational first; product mention subtle).
+5. **Schema.org injection.** CMS or publishing platform either auto-renders the `MedicalWebPage` JSON-LD block from the article frontmatter, or hand-pastes the commented JSON-LD at the bottom of each file into the page ``.
+6. **Publish.** Article goes live at its `canonical` URL. Update `lastReviewed` in the JSON-LD. Update internal cross-links between articles if needed.
+7. **Post-publish.** Monitor keyword rank via App Store Connect Analytics + external tool (AppFollow or Sensor Tower). Revisit article after 30 days for freshness edits.
+
+## Markdown Review Checklist
+
+Before marking an article `reviewed` in frontmatter, confirm each:
+
+### Structure
+- [ ] Primary keyword appears in H1 verbatim (or close paraphrase).
+- [ ] Meta description in frontmatter `description` field is 155 chars or fewer.
+- [ ] 4-6 H2 sections (not counting FAQ and References).
+- [ ] 1-3 numbered lists (for "which criteria", "steps", "pitfalls", etc.).
+- [ ] FAQ section with 3-5 questions at the bottom.
+- [ ] "Bottom Line" or equivalent closing section before References.

+
+### Keyword Density
+- [ ] Primary keyword appears 2-4 times total across H1, intro, body, and FAQ.
+- [ ] Secondary keywords each appear 1-2 times.
+- [ ] No single keyword exceeds 3x density (Apple ASO algorithm and Google both discount after that).

+
+## Schema.org Markup Notes
+
+Every article embeds a `MedicalWebPage` JSON-LD block at the bottom of the Markdown, in an HTML comment. Two deployment paths:
+
+### Path A: Publishing Platform Auto-Renders
+
+If the CMS reads frontmatter and generates schema.org metadata, delete the commented JSON-LD block and rely on the frontmatter. Confirm the CMS outputs:
+
+- `@type: MedicalWebPage`
+- `headline`, `description`, `datePublished`, `dateModified`
+- `author.@type: Organization` and `publisher.@type: Organization`
+- `about.@type: MedicalGuideline` with `guidelineSubject` populated
+- `audience.@type: MedicalAudience` with `audienceType: "EMS"`
+- `specialty.@type: MedicalSpecialty` with `name: "EmergencyMedicine"`
+- `reviewedBy.@type: Person` and `lastReviewed` (ISO date)
+
+### Path B: Hand-Paste JSON-LD
+
+If the platform does not auto-render, copy the commented JSON-LD from the article into the page template `` manually. Remove the outer HTML comment markers so the `
