To prevent fatigue, when should the team switch compressors?

• A. Every 1 cycle
• B. Every 2 minutes
• C. Every 10 minutes
• D. Every 5 cycles of CPR or 2 minutes

Answer: (D)

Rotating who delivers chest compressions helps keep the depth and rate at guideline levels. In two-rescuer CPR, switching about every 2 minutes is recommended because fatigue quickly reduces compression quality. Four to five cycles of CPR in that span is a practical way to gauge when to switch, which is why doing it every 5 cycles or about 2 minutes keeps the compressions effective. If you notice fatigue sooner, switch earlier to maintain consistent depth and recoil. When switching, keep interruptions to a minimum and hand off smoothly so the compression rhythm isn’t lost.
