Which practice is recommended to minimize interruptions during CPR?

• A. Limit interruptions to less than 10 seconds
• B. Pause every 15 seconds to reassess
• C. Stop compressions to check rhythm every 60 seconds
• D. Ventilate only after completing all compressions

Answer: (A)

The main idea is to keep blood flowing by minimizing pauses during CPR. Every interruption creates no-flow time, during which the heart and brain aren’t being perfused, so shorter pauses help preserve coronary and cerebral perfusion pressure and improve the chance of revival. Limiting interruptions to less than 10 seconds is the best approach because it allows essential tasks—like rhythm checks and delivering a shock—to be done quickly without keeping the chest wall still for too long. This keeps the chest compression cycle going with as little break as possible, maximizing the chest compression fraction and keeping perfusion high. Pausing every 15 seconds or checking the rhythm every 60 seconds would introduce longer breaks in chest compressions, dramatically reducing blood flow during CPR. Ventilating only after completing all compressions creates a longer interruption than necessary; in practice, breaths are delivered in a way that minimizes the pause, either integrated with compressions or in short, shallow pauses, depending on the resuscitation protocol. So keeping interruptions under 10 seconds consistently optimizes CPR by maintaining perfusion and enabling rapid rhythm assessment or shock delivery with minimal disruption.
