Frequent AED Questions


Frequently Asked AED Questions


What is an AED, and why are they vital in saving lives??

AED stands for ‘Automated External Defibrillator’, which is a device that detects lethal heart rhythms which stop the heart from pumping effectively, and then allows a rescuer to deliver a measured shock to a revert these rhythms, so the heart can pump effectively again.


Special Notes:

The only method available to revert lethal cardiac arrest rhythms is the use of a defibrillator e.g. AED.

Statistically, for every minute lost without defibrillation, you lose 10% probability of saving a life (With good

CPR you can extend this by several more minutes!)

The ‘Average Ambulance Response Time’ in the major metropolitan cities of Australia is approximately 16 minutes.

If you apply a measured shock to a person’s heart, suffering a lethal rhythm within the first minute, they have a 70% chance of survival.


Are they safe to use?

Yes. The AED talks you through the process, giving very simple directions on what to do and when.


Will I kill someone using a defibrillator?

No!  AED’s will only deliver a shock to a heart if it detects a lethal rhythm via electrodes you stick to the person’s chest.  These electrodes have sensors in them, and if they detect a normal heart rhythm they WILL NOT deliver a shock.


When do I use one?

You use a defibrillator, when you need to undertake CPR, which is performed on an unconscious person who is not breathing normally e.g. regular, rhythmic breathing.


Can I re-use a defibrillator?

Yes. You will simply need to replace the electrodes, which were stuck to the patient’s chest. These are consumables and are readily available.


How easy are they to use?

Anyone who understands simple instructions in English, and has CPR training can use the device.


Do I need special training?

No. But it is strongly advised by the Australian Resuscitation Council (ARC) that your staff regularly undertake training in CPR.


Please Note: Most current first aid training courses include training on defibrillators (or AEDs), as standard.  There is also a free instructional book, ‘Defibrillation & CPR’ supplied with every HeartOn A10  unit for additional background information.


How long does the battery last?

The main battery for the HeartOn A10 lasts 5 years. 

The electrodes & electrode charge battery need replacement every 2 years.


 Can I use them on children?

Yes. However, if the child is under 8 years of age, or under 25kgs in weight, you will need to use Child electrodes. For environments where children are at risk of cardiac arrest, such as from drowning or choking e.g. schools, public swimming pools, crèche’s or child care centres, it’s advisable to purchase a set of Child Electrodes.


Can I get sued using one?

To date nobody has ever been successfully sued for applying first aid under British Law

(Australia, Canada, USA, South Africa, UK)


Why would I need to use an AED?

If you DO NOT use a defibrillator on a cardiac arrest patient suffering a lethal heart rhythm, they will die.  Sadly it’s that simple.


The risk of someone suffering a cardiac arrest in your workplace, or home, increases with an ageing population, including from accidents such as electrical shock.


What is the likely-hood someone will have a heart attack?

Statistically for Men - Between the ages of 40-70 years there’s a 50% chance of a heart attack.

Statistically for Women: From the age of 40 years, there’s a 33% chance of suffering a heart attack. (Ref Heart Attack Facts – Heart Foundation).


Some causes of cardiac arrest are: Poor heart health, drowning, electric shock, choking, poisoning, trauma.
