In a two-rescuer CPR team, how should the roles of compression and ventilation be managed?

In a two-rescuer CPR team, alternating the roles of compressions and ventilation regularly is essential for maintaining the effectiveness of the CPR provided. This alternating approach helps to prevent exhaustion in the rescuers, allowing them to deliver high-quality compressions and ventilations without significant decline in performance.

Providing compressions alone, as suggested by some incorrect options, can lead to fatigue and a decrease in the efficacy of the lifesaving measures being performed. The American Heart Association guidelines recommend that rescuers switch roles approximately every 2 minutes or after about 5 cycles of 30 compressions to 2 breaths, ensuring that both rescuers stay fresh and capable of delivering the best possible care. Thus, managing roles by alternating regularly supports optimal CPR efforts and increases the chances of survival for the patient.
