Automatic External Defibrillators (AED)



What is an AED?

An automatic external defibrillator (AED) is a device that analyzes the heart rhythm of an unconscious person and delivers an electrical shock in an attempt to restore a normal rhythm. Don’t worry, an AED won't deliver a shock unless necessary.

When used as part of a first aid response, AEDs have been proven to increase the chances of surviving a cardiac arrest.

An AED should be applied to an unconscious person as soon as possible. For every minute the shock is delayed, there's about a 10% reduction in survival if the person is in cardiac arrest due to Ventricular Fibrillation (VF). CPR alone will not save a person in VF.

The University's AED network

We’ve had AEDs at the University since 2010. There is now a network of over 50, semi-automatic ZOLL AED Plus devices.

Where are they located?

Our AEDs are wall mounted in publically accessible areas. They are typically within a 3 minute walk to areas where we gather in large numbers or work with live electricity. Refer to the AED network map for specific locations.

Know also that Campus Security carry AEDs in their patrol vehicles.

ZOLL AED Plus with signage and accessories

The University’s network of AEDs is made up of semi-automatic ZOLL AED Plus units.

Our Zoll AED Plus devices include:

  • Adult electrode pads (single use) with a CPR hand placement landmark.
  • CPR barrier mask, scissors, disposable gloves, prep razor, a towel and a moist towelette.
  • CPR assistance technologies: CPR metronome, compression depth display and voice feedback saying “Push harder” or “Good compressions” as needed.
  • Cover designed to be placed under a person’s shoulders to help maintain an open airway. Don't use with suspected head or neck injury.
  • Australian Resuscitation Council basic life support flow chart.
  • Soft carry bag with adjustable shoulder strap.
  • Wall mounted units are housed in a transparent alarmed cabinet.

Who can use an AED?

Anyone can us an AED to help save a life. CPR training covers the use of AEDs. All accredited first aiders are trained in CPR.

How to use an AED

AEDs are easy to use. They guide users with step-by-step instructions using visual and voice prompts. Our AEDs will verbally request the responder to press the flashing shock button. AEDs won’t deliver a shock unless a shockable heart rhythm is detected.

An AED should be applied as soon as possible. CPR should be administered while the AED is being retrieved.

AEDs are safe to use. Just “Don’t Touch Patient” during shock delivery, as instructed by the voice prompt.

For more information see the ZOLL AED Plus Operators flow chart and ZOLL Basic life support poster.

Automatic self-test

Our AEDs perform an automatic self-check every 7 days to verify the following;

  1. adequate battery capacity,
  2. electrodes are connected,
  3. functional ECG circuitry,
  4. functional charge and discharge circuitry,
  5. functional microprocessor and software,
  6. functional CPR circuitry and sensor.


The result of this test is displayed on a status indicator window, visible from outside the transparent wall mounted cabinet.

 Status window shows passed test  Status windoe shows failed test

PASS:  an illuminated green tick mark indicates that the unit passed the last self-test and is ready for use.

FAIL:  an illuminated red “X” cross indicates the unit has failed its self-test and is not ready for use.

Failed tests need to be reported by calling 9351 5555.


How are they maintained?

Our network of AEDs is maintained by Safety Health & Wellbeing in accordance with ZOLL’s instructions.

Reporting an issue

Please call 9351 5555 to report any of the following:

  • AED has been used
  • The AED status window displays a red cross instead of a green tick

Other AEDs on campus

Some organisational units have their own AEDs to help meet their operational needs (eg. clinical operations, sports venues). These organisational units are responsible for maintaining their AEDs in accordance with the manufactures instructions.
