How often should rescuers switch roles when performing CPR?

• A. Every 5 cycles or about 2 minutes
• B. Every 10 cycles or about 5 minutes
• C. After each breath given
• D. Only when the AED arrives

Answer: (A)

Switching roles during CPR is critical to maintain high-quality chest compressions and prevent rescuer fatigue. Rescuers should switch every 5 cycles of CPR, which typically corresponds to about 2 minutes of performing chest compressions. This frequency ensures that each rescuer can provide effective compressions at the recommended rate and depth without becoming too fatigued, which can lead to decreased performance. Effective CPR relies on maintaining a consistent rhythm and quality of compressions, and regularly changing positions helps achieve that goal. The other options suggest either longer intervals between switches, which could lead to fatigue and reduced effectiveness, or switching roles after each breath or only when an AED arrives, neither of which aligns with the best practices for CPR. Regular switching every 2 minutes supports ongoing effectiveness and adherence to CPR guidelines established by organizations like the AHA.
