What is the main purpose of using an AED?

The main purpose of using an Automated External Defibrillator (AED) is to restore a normal heart rhythm by delivering a shock. When a person suffers from a sudden cardiac arrest, their heart may enter a chaotic rhythm known as ventricular fibrillation, which prevents the heart from effectively pumping blood. The AED analyzes the heart's rhythm and, if necessary, delivers a controlled electric shock to the heart. This shock can help reset the heart's electrical system and restore a normal rhythm, which is crucial for survival.

Understanding the role of the AED emphasizes the importance of using it as part of the chain of survival in cardiac emergencies, where prompt treatment can significantly increase the chances of survival. This immediate action is essential, as every minute without intervention decreases the likelihood of a positive outcome.
