In CPR, how often should you switch roles if you are working with another rescuer?

Switching roles every 2 minutes during CPR is essential because it helps prevent fatigue in rescuers, ensuring that high-quality chest compressions are maintained throughout the duration of resuscitation. High-quality compressions are crucial for effective circulation and oxygenation of the body, especially the brain, during cardiac arrest.

Rescuers need to be able to deliver compressions at the correct rate and depth, which can become challenging as fatigue sets in. By changing roles every 2 minutes, rescuers can maintain optimal performance, which significantly increases the chances of survival for the person in need. This is established as a best practice in CPR training and guidelines provided by organizations like the American Heart Association.

Frequent switching also helps to keep both rescuers alert and ready to respond if any changes in the situation arise, such as needing to use an AED or reassess the victim's condition.
