An automated external defibrillator (AED) is a lightweight and portable device that delivers an electric shock through the chest to the heart. This electric shock can stop an irregular heartbeat or arrhythmia and thus allow a normal rhythm to resume after a sudden cardiac arrest. AEDs make it possible for people to respond to a medical emergency where defibrillation is required and where heart malfunction is involved. Since AEDs are portable, they can be manipulated or operated by nonmedical people. This is where our AED training in Southern, Illinois comes in handy.
When AED pads are placed on a person’s chest, the AED then analyses whether that person’s heart is in a cardiac arrhythmia. The two main arrhythmias that will prompt an AED are ventricular tachycardia and ventricular fibrillation. In both instances, the heart acts in an erratic manner where the pumping of blood to the brain and other parts of the body becomes diminished.
An AED helps the heart to reset its natural pacemaker and begin to beat normally again after an electric shock is delivered. This shock temporarily stuns the heart and halts its activity. It then gives the heart to resume beating normally. That is why AEDs are made part of emergency response programs that also include the delivery of cardiopulmonary resuscitation. Both AED and CPR may be learned through training, as well as basic first aid training.
