What is the maximum duration one should perform CPR before switching rescuers?

When performing CPR, it is crucial to maintain high-quality chest compressions to maximize blood flow to vital organs. The recommended duration for a single rescuer to perform CPR before switching roles is approximately 2 minutes. This timeframe helps to prevent fatigue, ensuring that the compressions remain effective and consistent.

After roughly 2 minutes of continuous compressions, a change in rescuers allows for maintaining the strength and effectiveness of the compressions, as physical exhaustion can lead to a decline in the quality of CPR being performed. This systematic approach allows the team to work cooperatively and efficiently, ultimately increasing the chances of successful resuscitation.

Switching rescuers more frequently than every 2 minutes could interrupt the continuity of compressions, while waiting too long might lead to diminished effectiveness due to fatigue. This balance is essential in emergency situations to provide the best possible care to the patient.
