During CPR, how often should the rescuer switch positions to avoid fatigue?

Switching positions every 2 minutes during CPR is essential for maintaining effective compressions and reducing the risk of rescuer fatigue. CPR is physically demanding, and as a rescuer tires, the quality and effectiveness of chest compressions can deteriorate significantly.

By changing rescuers every 2 minutes, it allows for a fresh rescuer to take over, ensuring that compressions remain strong and at the appropriate rate and depth. This interval also aligns with many current CPR guidelines, which emphasize regular rotation to optimize the chances of successful resuscitation. This practice is especially important in situations where high-quality CPR is critical for maintaining blood flow to the brain and vital organs until advanced medical help arrives.

This approach helps maintain focus, stamina, and the overall efficacy of the life-saving effort. Rescuers should be vigilant about their own fatigue levels and communicate effectively during the switch to keep the process seamless.
