Two-rescuer CPR relies on rotating roles and changing positions to keep chest compressions strong and ventilations effective. After one rescuer completes a cycle of compressions and ventilations, the other rescuer should move to the opposite side of the patient. This swap lets the new rescuer take over with the appropriate posture and angle for chest compressions or bag-mask ventilation, reducing fatigue and minimizing interruptions to the flow of CPR. The other options don’t fit because pulse checks aren’t done during CPR, suctioning and ventilations occur during the cycle rather than as the post-cycle action, and continuing on the same side would miss the benefits of a proper handoff and optimal technique.
