When to Stop CPR: Resume Compressions Only If No Pulse; Stop When Pulse Returns

Per current AHA/ERC guidelines:

  • Check pulse every 2 minutes (during rhythm check/pulse check pause ≤10 sec).
  • If palpable pulse + organized rhythm: Stop compressions. Initiate post-cardiac arrest care (oxygenation, ventilation, hemodynamic support, targeted temperature management, coronary angiography if indicated).
  • If no pulse: Resume high-quality CPR immediately.
  • Do not stop for: Gasping, pupil check, family arrival, fatigue (switch rescuers).

Exception: If ROSC (return of spontaneous circulation) is achieved but patient re-arrests, restart CPR immediately.

High-quality CPR with minimal interruptions maximizes ROSC and neurologically intact survival.
