When performing two-rescuer CPR, the rescuers should switch roles every 5 cycles of CPR, which is approximately every 2 minutes. This switching frequency helps prevent fatigue, maintain the quality of chest compressions, and ensure high-quality CPR throughout the resuscitation effort. The switch should be done as smoothly and quickly as possible to minimize any interruption in compressions. This guideline is supported by the latest recommendations from the American Heart Association and other CPR experts, emphasizing the importance of role rotation every 2 minutes or about 5 cycles of compressions and breaths to optimize CPR effectiveness and patient outcomes.
