During two-person CPR, how is the task divided between rescuers?

The correct approach during two-person CPR is to have one rescuer perform compressions while the other gives rescue breaths and retrieves an AED when necessary. This division of labor is crucial as it allows one rescuer to focus entirely on maintaining proper compression depth and rate, which is essential for maintaining blood circulation to vital organs. At the same time, the other rescuer can concentrate on providing effective rescue breaths, ensuring that oxygen reaches the victim's lungs. Additionally, retrieving an AED is an important task that can be done simultaneously to prepare for defibrillation if needed.

Dividing the tasks in this manner maximizes the effectiveness of CPR and increases the chances of survival for the victim. The other options do not reflect the optimal collaboration needed for effective resuscitation, as they either involve both rescuers performing the same task or too much focus on secondary responsibilities that can detract from the efficiency of CPR.
