What affect can rescuer fatigue have on chest compressions?

Hi there!

Rescuer fatigue can have a large negative impact of chest compressions on the victim. Rescuer fatigue can cause the rescuer to only be able to give a short, not big and consistent chest compressions. They become tired and weak, which prevents them from being able to do good compressions.To prevent rescuer fatigue, there should be more than one rescuer and they should switch doing compressions between them.
