How often should you switch rescuers during CPR to maintain effectiveness?

• A. Every 1 minute
• B. Every 2 minutes
• C. Every 5 minutes
• D. As needed following exhaustion

Answer: (B)

Switching rescuers every 2 minutes is recommended to maintain the quality and effectiveness of CPR. This time frame allows for the fatigue that can settle in after continuous chest compressions, ensuring that the compressions remain effective and at the optimal rate of 100 to 120 compressions per minute. Regularly changing rescuers helps to prevent exhaustion and maintain the strength and depth of compressions, which are critical for perfusion to the vital organs. While it’s important to consider the condition of the rescuers and possibly switch sooner if someone shows signs of fatigue, the structured recommendation is to switch every 2 minutes for the best outcomes during a resuscitation effort.
