When should team members alternate roles in providing compressions to prevent fatigue?

Alternating roles in providing chest compressions is critical to maintaining the effectiveness of CPR and preventing fatigue among responders. The recommended frequency for changing compressing individuals is every 5 cycles of CPR, which corresponds to approximately every 2 minutes. This timing ensures that rescuers maintain high-quality compressions, as fatigue can significantly reduce the depth and rate of compressions and ultimately impact the chances of a successful outcome.

By following this guideline, team members can stay fresh and maintain their strength, which is essential for delivering adequate compressions. Each cycle consists of 30 compressions followed by 2 rescue breaths, and sticking to this schedule helps maximize the effectiveness of the care being provided.
