How often should responders switch roles during CPR?

During CPR, it is recommended that responders switch roles after every 5 cycles of chest compressions and rescue breaths, which translates to about 2 minutes of performing CPR. This frequency is important because both the person delivering compressions and the one providing rescue breaths can become fatigued, and fatigue can lead to diminished effectiveness in performing CPR. By rotating every 5 cycles, responders ensure that high-quality compressions are maintained throughout the duration of resuscitation efforts, maximizing the chances of survival for the patient. It's crucial to recognize the need for timely changes in roles to sustain the effectiveness and resilience of the team during an emergency situation.
