What role does an AED play in a cardiac emergency?

An Automated External Defibrillator (AED) plays a crucial role in a cardiac emergency by analyzing the heart's rhythms and delivering an electric shock if needed to restore a normal heart rhythm. When someone experiences a sudden cardiac arrest, their heart may be in an abnormal rhythm that prevents effective pumping of blood. An AED steps in by assessing the heart's condition through built-in sensors.

If the device detects a shockable rhythm, it prompts the user to deliver an electrical shock, which can help reset the heart's electrical system, allowing it to start beating effectively again. The prompt feedback and step-by-step audio or visual instructions make AEDs accessible for use by laypersons, often increasing the likelihood of survival in critical situations.

This vital function is particularly important in cardiac emergencies, where every second counts, as timely defibrillation can significantly improve outcomes.
