What is the maximum number of rescuers recommended to perform CPR on an adult victim?

The recommendation for two rescuers during CPR on an adult victim is rooted in the guidelines established by organizations such as the American Heart Association. This approach allows for one rescuer to perform chest compressions while the second rescuer manages the airway and provides rescue breaths, which creates an effective and efficient cycle of care.

With two rescuers, there is also the opportunity to manage fatigue, as providing high-quality chest compressions can be physically demanding. Rescuers can switch roles regularly to maintain the quality of compressions over time, which is crucial for maintaining blood flow to vital organs.

While more rescuers can certainly assist in other aspects of patient care or scene safety, for effective CPR, having two trained individuals working in tandem strikes a balance between efficiency and the ability to maintain high standards of care during the arrest situation.
