Lesson
ROSC & Post-Arrest Care
Objective: Recognize ROSC quickly and run a structured post-arrest package without losing the airway, pressure, or destination clock.
Why This Is Hard
ROSC is not the end of the call — it is a new unstable patient. Re-arrest is common. Teams either under-treat (“we got pulses, we’re done”) or over-ventilate and crash the pressure. You need a calm package: airway, breathing, circulation, ECG, temperature awareness, and destination.
Recognizing ROSC
- Organized rhythm with a palpable pulse (confirm carefully).
- Sudden sustained rise in EtCO₂ can support improving pulmonary blood flow — still confirm pulse per protocol.
- Spontaneous movement, breathing effort, improving color — helpful clues, not alone definitive.
Post-Arrest Street Package (Education)
- Airway/ventilation — avoid hyperventilation; titrate O₂ per protocol (many systems avoid prolonged hyperoxia).
- Blood pressure / perfusion — treat hypotension per protocol (fluids/pressors as authorized).
- 12-lead ECG when feasible — STEMI recognition drives destination.
- Treat reversible causes that remain (Hs/Ts themes).
- Glucose check when indicated by protocol.
- Temperature — prevent hyperthermia; targeted temperature management details are hospital/system-specific.
- Re-arrest readiness — pads stay on, epi and airway gear staged, continuous monitoring.
- Destination & notification — PCI-capable center when indicated; clear radio report.
Key Points for Paramedics
- Pulse checks must be real — do not call ROSC on artifact.
- EtCO₂ is an adjunct, not a substitute for pulse and patient assessment.
- Communicate: “ROSC at [time], BP…, EtCO₂…, 12-lead…, destination…”
- Family communication matters but do not drop monitoring to counsel at length.
Field Pitfalls
- Removing pads “to clean up” before hospital.
- Bagging at 20+ after ROSC.
- Missing STEMI because nobody ran a 12-lead.
- Long scene times without a purpose after ROSC.
Practice
Tabletop: VF arrest → shock → ROSC. Speak a 30-second post-ROSC plan. Related: PEA, Asystole vs Fine VF.
