How often should team members switch roles during CPR to maintain effectiveness?

Switching roles during CPR is crucial for maintaining high-quality chest compressions and preventing fatigue among rescuers. It is recommended that team members change positions every two minutes. This two-minute interval helps to ensure that each provider can perform compressions at the optimal depth and rate without becoming overly fatigued, which can lead to decreased effectiveness.

Fatigue can compromise the quality of compressions, leading to inadequate circulation during a cardiac arrest and therefore affecting the chances of successful resuscitation. By rotating compressions every two minutes, team members can stay fresh and alert, maintaining the critical effectiveness of CPR until advanced life support is initiated or the patient recovers.
