How often should rescuers change positions during adult CPR?

The guideline for changing positions during adult CPR is to do so every two minutes or every five cycles of chest compressions. This recommendation is supported by current CPR protocols to ensure high-quality, effective compressions while minimizing fatigue among the rescuers.

Switching rescuers every two minutes allows for maintaining optimal compression depth and rate, while also reducing the risk of provider fatigue that can lead to diminished performance. CPR is physically demanding, and having a plan for rotation helps to keep rescuers fresh, ensuring continuous and effective resuscitative efforts.

In contrast to the other suggested intervals, the two-minute mark aligns with the typical rhythm of CPR, which often operates in cycles of compression followed by ventilation. This interval also fits within the guidelines set forth by major resuscitation councils, promoting the best chance for patient survival.
