What is the recommended maximum duration to interrupt chest compressions?

• A. Less than 20 seconds
• B. Less than 60 seconds
• C. Less than 10 seconds
• D. Less than 30 seconds

Answer: (C)

The main idea is that chest compressions should be as continuous as possible because each compression builds and maintains blood flow to the heart and brain. When you pause, the blood pressure falls and brain and heart perfusion drop, making it harder to achieve a good outcome. That’s why the recommended maximum interruption time is under 10 seconds—keep pauses very brief, especially during rhythm checks or defibrillation, and resume compressions within that short window. Longer pauses, like those implied by the other options, would allow perfusion to decline and reduce the chances of return of spontaneous circulation.
