Automated External Defibrillators (AED’s)

What are they and how do they work?

A defibrillator is a device that defibrillates (shocks) the heart to convert the hearts rhythm from a life threatening “arrhythmia” (abnormal electrical heart rhythm - which means the heart wont pump blood) to a normal heart rhythm.

An AED is a small device which is “automated”. This means that it automatically assesses the heart’s rhythm and tells the user what to do – i.e., push the button to defibrillate. They are much smaller, simpler, and easier to use than the ones we use in hospital, or Paramedics use in the community.

As AED’s are becoming more widespread in the general community and are relatively cheap for a lifesaving device, Australian Sailing believes consideration should be given to purchasing one for Yacht clubs and/or race committees.

Why would I have an arrhythmia?

Abnormal heart rhythms (arrhythmias) occur for multiple reasons – including (but not limited to):
•    After a heart attack
•    Hypothermia (cold)
•    Chest trauma
•    Abnormal heart conducting (electrical) system
•    Side effect of some medications

Do they work?

There is good evidence that early CPR and Defibrillation can be lifesaving. For the most serious arrhythmias - the earlier defibrillation occurs, the better the outcome. For this reason, we suggest they should be carried on race committee vessels.

First Aid training in CPR and how to use an AED is highly recommended. To find a first aid training course contact St John First Aid Training on 1300 360 455.

What sort should I buy?

There are many types of AEDs on the market, however either a waterproof one or a robust one in a waterproof case is recommended. It should meet the Australian standard (defined in Therapeutic Goods Act 1989) and relay audible instructions in English.

If the patient is unresponsive or not breathing – call 000 (triple zero)
