How often should the rescuer change position during CPR with multiple rescuers?

During CPR with multiple rescuers, it is recommended that the rescuer performing chest compressions change positions every 2 minutes. This interval allows for effective and high-quality compressions while preventing fatigue in the person giving compressions. The 2-minute mark is aligned with the cycle of performing CPR as it commonly coincides with the time it takes to complete five cycles of 30 compressions and two rescue breaths.

This practice ensures that the compressing rescuer maintains adequate force and a steady rhythm, which is crucial for maintaining blood flow to the brain and other vital organs during a cardiac emergency. By changing rescuers at this frequency, the team can sustain a higher quality of CPR, thereby improving the chances of patient survival and recovery.
