How often should rescuers switch roles during CPR if two people are present?

Switching roles every 2 minutes during CPR for rescuers is essential to ensure that both individuals remain effective and focused. CPR can be very physically demanding, leading to fatigue, which can reduce the quality of chest compressions. By changing roles at this interval, each rescuer has the opportunity to rest briefly, allowing them to maintain optimal performance during their shifts.

This practice not only enhances the efficacy of the resuscitation effort but also ensures that both rescuers stay alert and can continuously provide high-quality care. Regularly swapping roles helps in sustaining energy levels and provides better overall patient outcomes. Additionally, it fosters teamwork and communication, which are vital components of effective CPR.
