When should two responders switch positions during CPR?

Switching positions during CPR is important to maintain the quality of chest compressions. The correct timing for this switch is after approximately 2 minutes of continuous CPR. This interval allows the responders to manage fatigue, ensuring that compressions remain effective and of high quality throughout the resuscitation effort.

Research indicates that, regardless of the fitness level of the responders, performing high-quality compressions can become increasingly difficult to maintain over extended periods due to physical fatigue. Therefore, switching every 2 minutes helps mitigate this issue and keeps the compression rate and depth within the recommended guidelines.

By adhering to this timing, responders can provide more consistent and effective care, which is critical in improving survival rates in cardiac arrest situations.
