What is the maximum allowed interruption time to compressions to maintain high-quality CPR?

• A. Less than 20 seconds
• B. Unrestricted
• C. Less than 5 seconds
• D. Less than 10 seconds

Answer: (D)

The main idea is that chest compressions should be continuous to keep blood flowing to the heart and brain. Each interruption reduces the pressure that drives blood to vital organs, so long pauses can make it harder to restart effective circulation. For high-quality CPR, the goal is to keep interruptions very short—about 10 seconds or less. This limit covers necessary tasks like rhythm checks, defibrillator analyses, or switching responders, while still preserving as much chest compression time as possible. If a task would take longer than 10 seconds, the team should resume compressions as soon as possible and complete the task quickly or coordinate the task with the next compression cycle. That’s why under ten seconds is the best standard: it minimizes loss of perfusion while allowing essential actions. The other options imply longer or unrestricted pauses, which would allow perfusion to fall and impede recovery, or are impractical in real rescue situations, so they’re not aligned with maintaining high-quality CPR.
