What action supports 2 rescuer CPR Alternating compressor role every 2 minutes?

In a two-rescuer CPR scenario, the action that supports alternating the compressor role every 2 minutes is the clear communication between rescuers. After every 2 minutes of chest compressions, the rescuers should pause briefly to switch roles, ensuring that one rescuer continues to provide compressions while the other takes over. This rotation helps to prevent fatigue and maintain effective compressions, which are crucial for maintaining blood circulation in a victim during cardiac arrest.
