How often should rescuers switch during CPR to avoid fatigue?

In the context of performing CPR, it is crucial for rescuers to maintain the highest quality of chest compressions to be effective. Fatigue can set in quickly when performing CPR, which can diminish the strength and efficacy of compressions. This is why regularly switching roles among rescuers is recommended.

Switching every 2 minutes is based on guidelines that help ensure that the individual performing chest compressions remains as effective as possible. Research indicates that after about 2 minutes of continuous chest compressions, the performance can begin to decline due to fatigue, increasing the importance of making timely changes to rescuers. This interval allows the compressor to maintain optimal force and rate in compressions, which are critical for maintaining blood circulation.

Adhering to this timing has been shown to lead to better patient outcomes in resuscitation efforts, emphasizing the need for collective responsibility and teamwork in emergencies.
