What is the recommended frequency for switching off during compressions if the provider is fatigued?

The recommended frequency for switching off during compressions is every 2 minutes. This guideline is based on the physiological demands placed on rescuers during high-quality chest compressions, which can become physically exhausting. When providers continue to perform compressions without switching off, the quality of compressions can deteriorate due to fatigue, leading to decreased effectiveness in circulating blood to the vital organs of a patient in cardiac arrest.

Switching off every 2 minutes aligns with the guideline to ensure that compressions remain consistent in depth and rate, ideally at a rate of 100 to 120 compressions per minute with a depth of at least 2 inches for adults. This also allows rescuers to maintain stamina and energy throughout the resuscitation effort, enhancing the overall chances for a positive patient outcome. In a high-stress scenario such as cardiopulmonary resuscitation (CPR), it is crucial to have a plan for personnel rotation to minimize fatigue and maximize the efficiency of the intervention being provided.
