How often should you change the person performing CPR?

Changing the person performing CPR every 2 minutes is recommended primarily to prevent fatigue. CPR is a physically demanding intervention, and the quality of chest compressions can decrease significantly as the provider becomes tired. By rotating the CPR provider around this interval, the effectiveness and depth of compressions can be maintained, which is crucial for effective circulation and oxygen delivery during cardiac arrest.

Additionally, this practice aligns with guidelines from resuscitation authorities which emphasize the importance of high-quality chest compressions. It also allows for the opportunity to reassess the situation briefly—checking the victim’s response if appropriate and ensuring that the CPR is being performed correctly.

Maintaining a high quality of CPR throughout the duration of the resuscitation attempt significantly impacts the chances of survival and favorable outcomes for the patient. Thus, the 2-minute rotation provides a balance between sustaining physical effort and ensuring the best possible care for the patient in a critical situation.
