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

The primary purpose of an Automated External Defibrillator (AED) is to restore normal heart rhythm. An AED is a portable device designed to recognize and treat life-threatening cardiac arrhythmias, specifically ventricular fibrillation and pulseless ventricular tachycardia. When a person experiences a sudden cardiac arrest, their heart may beat chaotically or stop beating altogether. The AED analyzes the heart's rhythm and delivers an electric shock, if necessary, to help the heart reestablish an effective rhythm. This defibrillation process can significantly increase the chances of survival when used promptly in conjunction with CPR.

While monitoring heart rate, providing medication, or replacing CPR are important aspects of cardiac care, they don't capture the primary function of an AED. The device specifically targets the electrical disturbances in the heart that need to be corrected to restore a healthy rhythm, emphasizing its vital role in emergency response situations.
