How often should rescuers switch roles during continuous CPR to minimize fatigue?

Switching roles every 2 minutes during continuous CPR is recommended to minimize rescuer fatigue. This time frame is significant because it allows each rescuer to perform high-quality compressions and ventilations without becoming overly exhausted, which can compromise the effectiveness of the CPR being administered. Fatigue can lead to decreased compression depth, rate, and overall quality, potentially impacting the patient's chance of survival.

By changing roles every 2 minutes, the rescuers can maintain their energy levels, ensuring that compressions are delivered at the appropriate rate of 100 to 120 per minute, with a depth of at least 2 inches in adults. This practice aligns with the guidelines established by organizations such as the American Heart Association, which emphasizes the importance of high-quality CPR. Regularly rotating roles also allows for a more structured approach to CPR, creating opportunities for brief assessments of the patient's condition and the quality of CPR being delivered. This collaborative effort ensures that rescuers can work effectively as a team, maximizing the chances of a positive outcome for the patient.
