Defibrillator FAQ

Our customer services team regularly receive enquiries regarding defibrillators so we have listed some of the most popular questions and answers:

What is an Automatic External Defibrillator?

Automatic External Defibrillator (or AED for short) is used to administer an electric shock to a person suffering from a heart attack. They’re specifically designed to allow non-medical personnel to save lives.

How does an AED work?

There are two pads, which are connected to the AED, these are placed on the patient's chest. A computer inside the AED then analyses the patient's heart rhythm and determines if a shock is required to save the victim. If required, the AED uses voice instructions to guide the user through saving the person's life.

Why do we need AEDs?

AEDs are capable of saving lives. When a person suddenly suffers from a sudden cardiac arrest ("SCA"), their heart's normal rhythm becomes irregular or chaotic. Every minute that the heart is not beating lowers the odds of survival by 7% to 10%. Very few people survive after 10 minutes without a defibrillator.

What is Sudden Cardiac Arrest (SCA)? 

Sudden cardiac arrest is when the heart's normal heart rhythm suddenly becomes chaotic. The heart is then incapable of pumping blood effectively, causing the victim to collapse, stop breathing, become unresponsive and having no detectable pulse. When used on a victim of SCA, the AED can be used to administer a life-saving electric shock that restores the heart back to its normal beat.

Is SCA the same as a heart attack?  

Not really. Both the heart attack (myocardial infarction) and a sudden cardiac arrest have to do with the heart, but they are different problems. SCA is an electrical problem; a heart attack is a "plumbing" problem. Sometimes a heart attack, which may not be fatal in itself, can trigger a sudden cardiac arrest. It can happen to anyone at anytime. Children, teenagers, athletes and the elderly can potentially have SCAs. While the risk of SCA increases with age and in people with heart problems, a large percentage of the victims are people with no known risk factors.

What is the recommended treatment for SCA?  

As of now, defibrillation is the only available treatment proven to restore a normal heart rhythm.

How much time do I have to respond if someone has a sudden cardiac arrest?

Within minutes. Defibrillate a patient within 3 minutes and the chances of survival are 70%. The chances of survival become slim after 10 minutes have passed.

What does the Irish Heart foundation say about AEDs?

The Irish Heart Foundation strongly supports having AEDs in public areas such as sports arenas, office complexes, schools, doctors' offices, shopping centers, golf courses, airports, and other public areas.
