Sudden cardiac arrest is a life-threatening emergency where every second matters. It occurs when the heart suddenly stops beating, cutting off blood flow to the brain and vital organs. In such critical moments, Automated External Defibrillators (AEDs) serve as one of the most effective tools for survival. Their ability to deliver a controlled electric shock to restore normal heart rhythm can mean the difference between life and death. Despite their proven effectiveness, AEDs are still underutilized in public spaces, homes, and workplaces. This article explores how AEDs work, their life-saving potential, and why broader awareness and accessibility are vital.
