Who in a BLS team is responsible for operating the AED and alternating with the Compressor?

In a Basic Life Support (BLS) scenario, the role of operating the AED (Automated External Defibrillator) and alternating with the Compressor is typically assigned to the individual designated as the Monitor/Defibrillator. This team member is responsible for ensuring that the heart rhythm is assessed and, if needed, delivering defibrillation while coordinating with the Compressor, who is performing chest compressions.

This dual responsibility is crucial because effective CPR and timely defibrillation are both critical factors in improving survival rates for out-of-hospital cardiac arrest. The Monitor/Defibrillator must stay alert to the patient's condition and be ready to respond appropriately when the AED indicates that a shock is advised. This allows for minimal interruptions to chest compressions, which should only cease briefly for the delivery of a shock and immediately resume afterward.

The other roles within the BLS team—such as the Airway, who is responsible for maintaining an open airway and providing rescue breaths, and the Team Leader, who oversees the entire response and ensures the team works efficiently—do not typically handle the AED directly or switch roles with the Compressor. This delineation of responsibilities helps maintain clarity and effectiveness during a critical emergency response.
