Which action best helps maintain high-quality CPR during defibrillation pauses?

• A. Remove airway devices during shock
• B. Minimize interruptions to CPR during defibrillation
• C. Increase ventilation pauses during shocks
• D. Pause CPR for defibrillation as long as possible

Answer: (B)

The main concept is that keeping chest compressions going with as few interruptions as possible during defibrillation is essential for high-quality CPR. When CPR is paused, perfusion pressure to the heart and brain falls quickly, so minimizing the time away from compressions during shock delivery preserves blood flow and improves the chance of return of spontaneous circulation. The best approach is to charge and deliver the shock with the shortest possible hands-off time and immediately resume compressions as soon as the shock is delivered. After the shock, pick up the CPR cycle again without delay and continue high-quality compressions. Why the other options aren’t as good: removing airway devices during shock can jeopardize airway protection and cause delays; increasing ventilation pauses during shocks reduces oxygen delivery and worsens perfusion; pausing CPR for defibrillation as long as possible defeats the goal of maintaining blood flow and lowers survival chances.
