When should you switch rescuers during CPR?

Switching rescuers every 2 minutes during CPR is essential for maintaining effective compressions and minimizing fatigue. Continuous high-quality chest compressions are critical during cardiac arrest, and prolonged efforts by a single rescuer can lead to decreased performance over time. By changing rescuers at this interval, both rescuers can maintain a strong and effective compression rate of at least 100-120 compressions per minute, which is necessary for optimal blood circulation to vital organs.

This practice aligns with guidelines provided by organizations such as the American Heart Association, emphasizing the importance of teamwork and strategy in life-saving situations. It ensures that each rescuer can deliver compressions with sufficient force and speed while preventing exhaustion, ultimately increasing the chances of a successful outcome for the patient.
