How often should rescuers switch performing chest compressions during CPR?

The recommended practice is to switch performing chest compressions every 2 minutes during CPR. This time frame is based on research indicating that rescuer fatigue can significantly reduce the quality of compressions over time. By changing rescuers every 2 minutes, it ensures that high-quality compressions can be maintained.

Continuous high-quality chest compressions are crucial for effective CPR, as they improve blood flow to vital organs, especially the heart and brain. This interval allows for a brief assessment of the patient and ensures that any rescuer who takes over is not fatigued, which is essential for maintaining the correct rate and depth of compressions.

While it's important to monitor for rescuer fatigue, adhering to the 2-minute guideline standardizes the process and reduces variability in resuscitation efforts. This practice is particularly valuable in a team scenario, as it allows other rescuers to maintain their performance standards without compromising the care provided to the patient.
