When should CPR providers switch positions during resuscitation?

The correct guideline for switching positions during resuscitation is to do so every 2 minutes. This timing is based on the physiological demands placed on the provider performing chest compressions. After about 2 minutes of continuous compressions, fatigue can significantly reduce the quality and effectiveness of the compressions being delivered.

Switching providers at this interval not only helps maintain high-quality CPR but also ensures that the compressions remain deep and at the recommended rate. Quality compressions are critical for maintaining blood flow to the vital organs during a cardiac arrest. Maintaining a consistent rhythm and ensuring the compressions remain effective during the entire resuscitation process is paramount.

While frequent changes are beneficial, switching too often can disrupt the flow and may not provide the necessary stability in the rhythm of compressions. Therefore, every 2 minutes strikes a balance between managing fatigue and maintaining the quality of care provided to the patient in cardiac arrest.
