How often should rescuers switch positions during CPR?

Switching positions every 2 minutes during CPR is important to ensure that rescuers maintain high-quality chest compressions without becoming fatigued. Fatigue can significantly reduce the effectiveness of compressions, which is critical for maintaining blood circulation to vital organs during a cardiac emergency. Regularly switching allows rescuers to stay fresh and maintain their force and accuracy, thereby maximizing the chance of a successful outcome.

Other options suggest longer intervals, which may lead to decreased compression quality as the responder tires. The practice of switching every 2 minutes aligns with guidelines provided by organizations such as the American Heart Association, emphasizing the need for both effective compressions and the well-being of the rescuers involved in the process.
