What is the correct technique to switch roles in two-rescuer CPR?

• A. Switch approximately every 30 seconds
• B. Switch approximately every 2 minutes with a smooth transfer to minimize interruptions
• C. Switch only when the AED prompts
• D. Do not switch roles at all during CPR

Answer: (B)

Maintaining high-quality chest compressions with minimal interruptions is the goal. In two-rescuer CPR, one person performs compressions while the other provides ventilations, and you should switch roles about every two minutes. This interval helps prevent fatigue from reducing compression depth and rate, which keeps perfusion pressures up and improves the chances of return of spontaneous circulation. A smooth transfer means clear communication and a quick, seamless handoff: the rescuer currently giving compressions signals the switch, briefly pauses to allow the other to take over, and the new rescuer immediately continues compressions with proper depth and rate. The pauses should be as short as possible to avoid losing perfusion. Don’t wait for an AED prompt to switch, and don’t switch too often (like every 30 seconds) or not at all, as both can degrade compression quality.
