How often should someone switch performing chest compressions during CPR?

Switching the person performing chest compressions every two minutes is crucial during CPR because it helps maintain the quality and effectiveness of compressions. Continuous compressions can lead to fatigue, which may decrease the depth and rate necessary for proper blood circulation. By rotating the rescuers every two minutes, each person can maintain peak performance, ensuring that the compressions remain effective and consistent. This strategy is particularly important when CPR is performed on adults, as high-quality compressions are vital to increase the chances of survival. Therefore, adhering to this two-minute interval is a key practice in resuscitation to maximize the effectiveness of CPR.
