What is the primary function of an Automated External Defibrillator (AED)?

The primary function of an Automated External Defibrillator (AED) is to deliver electrical shocks to the heart in cases of life-threatening arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia. The AED is designed to analyze the heart's rhythm and, if necessary, provide a shock to restore a normal heart rhythm. This immediate intervention can be critical in increasing the chances of survival for a person experiencing a cardiac arrest.

While the AED can analyze and detect certain heart rhythms, its main role is not to continuously monitor heart rhythms but to intervene only when a shockable rhythm is detected. Airway management and medication administration are not functions of the AED; those require separate equipment and training. Thus, the focus of the AED is purely on the delivery of electrical shocks to potentially save a life in emergency scenarios involving cardiac issues.
