How often should personnel performing compressions change positions?

Changing positions for personnel performing compressions is crucial for maintaining effective CPR. The recommended practice is to switch compressing personnel every 2 minutes. This is based on the understanding that fatigue can significantly reduce the quality and effectiveness of chest compressions over time. When rescuers alternate every 2 minutes, it allows them to provide high-quality compressions while reducing the physical strain and maintaining adequate depth and rate of compressions, which are vital for successful resuscitation efforts.

This interval aligns with the standard guidelines set forth by organizations such as the American Heart Association, emphasizing that frequent changes help sustain the efficacy of the compressions, thus enhancing the patient's chance of survival. Frequent rotation is vital to avoid interrupting the rhythm and effectiveness of the resuscitation effort.
