What is the purpose of using an Automated External Defibrillator (AED)?

The purpose of using an Automated External Defibrillator (AED) is to deliver an electric shock to restore a normal heart rhythm. During sudden cardiac arrest, the heart may enter a chaotic rhythm known as v-fib (ventricular fibrillation) or may be completely unresponsive (asystole). The AED is designed to analyze the heart's rhythm and determine if a shock is necessary. If a shock is indicated, the AED delivers it, which can help to reset the heart's electrical system and potentially allow the heart to resume a normal rhythm.

The other options address different aspects of medical care but do not pertain to the main function of an AED. For instance, delivering medication to stabilize heart function is a different intervention that may occur in conjunction with other treatments but does not involve the AED. Monitoring heart activity is conducted through ECG machines or other monitoring devices, rather than the AED itself. Providing artificial ventilation is a separate process that involves ensuring the patient receives adequate oxygen, which is important for overall resuscitation but is not the primary function of an AED.
