Automated External Defibrillator: All You Need to Know

If you've ever watched a medical drama on television, you've seen a patient revived by a health care worker who says "Clear" before shocking the patient's chest to get the heart beating again.

You are not alone in wondering what an AED is and why they seem to be positioned in most offices and public buildings. More individuals than ever before are fascinated by these technologies due to their widespread availability.

This device is known as a defibrillator, and its use is not restricted to hospitals. Automated external defibrillators (AEDs) are available at home, in schools, and several public locations. These compact, portable gadgets can be obtained without a prescription.

What Exactly Is an Automated External Defibrillator?

AEDs are electronic medical devices that are used to resuscitate people whose hearts are not beating properly. It is battery-powered and has adhesive defibrillator pads put to the chest to allow an electrical current to flow through the heart to reset its average electrical current. A standard, regular, or ordered electrical rhythm is required for the heart to contract and pump blood throughout the body.

When Is an Automated External Defibrillator Needed?

SCA is a life-threatening disorder of the heart. CPR and early use of a defibrillator can increase the odds of survival in an emergency. 

AEDs, which are also called "public access defibrillators," are used to help people who have had a heart attack. It is a high-tech but easy-to-use medical device that can analyze the heart's rhythm and, if needed, send an electrical shock, called defibrillation, to help the heart get back to a normal rhythm.

What Is Sudden Cardiac Arrest (SCA)?

One of the most common causes of sudden death is cardiac arrest. When the heart's muscle abruptly and unexpectedly stops contracting, it can cause a sudden cardiac arrest. A lack of blood supply to important organs causes them to shut down.

Sudden cardiac arrest is fatal unless treated within minutes. As the heart flops around, it causes the body's potassium levels to rise. This keeps the heart from contracting normally, but it also causes the heart's cells to begin to die.

How Is an Automated External Defibrillator Used?

A trained operator using an AED does not need to be a medical professional. AEDs are typically attached to the wall or the wall under the counter, and they come with emergency instructions that go into effect when a button is pushed. AEDs are designed to guide non-medical personnel through a series of actions that result in the delivery of a shock.

What Heart Rhythms Are Treated with an Automated External Defibrillator?

1. Ventricular Fibrillation (Vf)

Ventricular fibrillation (VF) is the most common emergency that requires an automated external defibrillator. This occurs when the heart's ventricles quiver instead of contracting normally. This can lead to cardiac arrest within minutes.

2. Ventricular Tachycardia (VT)

Ventricular tachycardia (VT) is another life-threatening heart disorder that requires immediate treatment with an AED. The heart is beating too fast, but with regular rhythms.

Ventricular tachycardia is a dangerous condition that may lead to ventricular fibrillation, a fatal heart rhythm.


Automated external defibrillators are compact devices that come in various colours, are easy to use, and are essential in certain life-threatening situations.
