How often should providers switch off giving compressions during CPR to ensure high-quality performance?

Every 1 minute
Every 2 minutes
Every 3 minutes
Every 5 minutes

The correct answer is: Every 2 minutes

High-quality chest compressions during CPR are essential for maintaining blood flow to the heart and brain. Providers should switch off giving compressions every 2 minutes to minimize fatigue and ensure that the compressions remain effective and high-quality. Performing compressions for extended periods without a break can lead to decreased effectiveness due to tiredness, which can impact the depth and rate of compressions. Frequent switching allows for the delivery of consistent compressions at an optimal rate of 100 to 120 compressions per minute, which is critical for improving outcomes in a cardiac arrest situation. By adhering to the 2-minute guideline for switching roles, providers can manage their physical endurance while maintaining the quality of care needed during the resuscitation process.
