When is the appropriate time to switch rescuers during CPR?

The appropriate time to switch rescuers during CPR is every 2 minutes or when the current rescuer feels fatigued because maintaining high-quality chest compressions is crucial for the effectiveness of CPR. Fatigue can lead to a decrease in compression depth and rate, which can compromise blood flow to vital organs.

Switching every 2 minutes aligns with the recommended guidelines provided by organizations such as the American Heart Association, which emphasize that frequent changes among rescuers can help ensure that compressions remain effective and continuous. Additionally, recognizing when a rescuer feels fatigued is important because it can directly impact the quality of the CPR being delivered. Therefore, implementing a strategy that allows for regular changes reduces the risk of fatigue-related deterioration in performance, ultimately improving patient outcomes during a cardiac emergency.

Other options may suggest longer intervals or less consideration of rescuer fatigue, which could compromise the quality of the CPR.
