What is automated external defribrillator?

An Automated External Defibrillator (AED) is a portable medical device used to diagnose and treat life-threatening cardiac arrhythmias, specifically ventricular fibrillation and pulseless ventricular tachycardia. It delivers an electric shock to the heart to restore a normal rhythm. AEDs are designed for use by laypersons and provide audio and visual prompts to guide users through the process of administering defibrillation. They are commonly found in public spaces and are crucial for improving survival rates in cardiac arrest situations.
