How often should you switch compressors during two-rescuer CPR?

The recommended practice is to switch compressors every 2 minutes during two-rescuer CPR to ensure that high-quality chest compressions are maintained throughout the resuscitation effort. This time frame is aligned with the guidelines set forth by organizations such as the American Heart Association, which emphasize the importance of changing compressors regularly to avoid fatigue. Fatigue can lead to a decrease in the effectiveness of compressions, including factors like compression depth and rate, which are critical for improving the chances of successful resuscitation.

By adhering to the 2-minute rule, the rescuers can ensure that both individuals remain effective in their roles, allowing one person to recover briefly while maintaining continuous CPR. This strategy maximizes the effectiveness of the intervention, improves the likelihood of restoring spontaneous circulation, and ultimately enhances patient outcomes in cardiac arrest situations.
