How often should rescuers switch during CPR?

Rescuers should switch every 2 minutes during CPR to maintain the effectiveness of the compressions and minimize fatigue. Maintaining high-quality chest compressions is essential for effective CPR, and switching providers regularly ensures that the compressions remain strong and effective throughout the resuscitation effort.

The 2-minute interval aligns with the recommendations from recognized guidelines, which emphasize that rescuers should alternate to refresh their strength and stamina, ensuring that the compressions continue to be delivered with the correct rate and depth. Fatigue can lead to a decrease in the quality of compressions, which is why this strategy is important. By allowing the rescuers to switch at this interval, it also helps to maintain focus and readiness for other critical actions that may be necessary, such as ventilations or utilizing an AED when available.
