In a two-rescuer CPR scenario, what is the recommended switch time for rescuers?

In a two-rescuer CPR scenario, the recommended switch time for rescuers is every thirty seconds. This interval is crucial as it helps maintain high-quality CPR by ensuring that each rescuer is not overly fatigued, which can lead to a decrease in the effectiveness of chest compressions. Compressions must be delivered consistently and at the correct rate and depth; fatigue can compromise these critical aspects.

Switching every thirty seconds allows for fresh energy and focus, ensuring that the compressions remain strong and effective. It aligns with the guidelines established by organizations such as the American Heart Association, which emphasize the importance of minimizing interruptions and maintaining optimal perfusion during the resuscitation effort.
