How often should CPR team members switch roles during compressions?

In a CPR scenario, it is recommended that CPR team members switch roles approximately every two minutes. This practice helps to prevent fatigue among those performing chest compressions, as sustained compressions can become less effective when a provider becomes tired. Fatigue can lead to a decrease in the depth and rate of compressions, which are critical for maintaining blood flow to the heart and brain during a cardiac arrest.

Switching every two minutes allows the rescuer performing compressions to maintain optimal performance and also ensures that all team members remain alert and ready to assist with other responsibilities, such as maintaining an open airway or using an AED. Regular role changes keep the team functioning efficiently and improve outcomes for the patient.
