Question: 1 / 400

How often should rescuers switch roles during CPR if there is a second rescuer available?

Every 2 minutes

The recommended practice for rescuers to switch roles during CPR, especially with a second rescuer available, is every 2 minutes. This timing aligns with the guideline to perform CPR in cycles, allowing each rescuer to maintain optimal strength and focus. After about 2 minutes, fatigue can start to set in, which may reduce the effectiveness of chest compressions. By switching every 2 minutes, both rescuers can ensure that high-quality compressions are consistently delivered, significantly increasing the likelihood of a positive outcome.

Rescuers should focus on maintaining the rhythm and depth of compressions, as fatigue can lead to reductions in performance. The importance of switching rescuers at this interval cannot be overstated, as maintaining the quality of CPR is critical in such emergency situations.
