When should you change compressors during CPR?

Changing compressors during CPR is critical to maintaining effective chest compressions. The recommended timing for switching compressors is approximately every 2 minutes or whenever the person performing compressions shows signs of fatigue. This interval helps to ensure that compressions remain high-quality and are delivered at the appropriate rate and depth. Fatigue can adversely affect the effectiveness of compressions, leading to inadequate perfusion and reduced chances of survival for the patient.

Additionally, changing compressors every 2 minutes aligns with the rhythm of the rescue cycle, allowing time for rhythm checks and freeing up the compressor for vital assessments without significantly delaying the resuscitation effort. The focus is on maintaining continuous, consistent compressions, which are crucial for supporting circulation and enhancing the chances of successful resuscitation. It's also important to note that changing compressors too frequently or without regard to fatigue levels could disrupt the compressions and negate the benefits of having a fresh person take over.
