How often should rescuers in a team change the compression role to maintain effectiveness?

To maintain the effectiveness of chest compressions during CPR, it's essential for rescuers to change roles regularly. The recommended practice is to switch compressing rescuers every 2 minutes or after about 5 cycles of CPR. This ensures that each rescuer stays fresh and continues to provide high-quality compressions, which are crucial in maintaining blood flow and oxygenation to vital organs. Fatigue can lead to a decline in the quality of compressions, making frequent changes necessary to sustain an effective response during a resuscitation attempt. By adhering to this guideline, the team maximizes the chances of a favorable outcome for the patient.
