The Resus Council advise that to save a person’s life, a defibrillator must be used to deliver a shock, if possible, within 3 minutes. Consider how many units you need to achieve this across the area you want to protect.


If a shockable heart rhythm is detected through the electrode pads a semi-automatic defibrillator will advise that a shock is required and instruct the rescuer to press a button. A fully-automatic defibrillator advises that a shock is required and warns the rescuer to stand clear, then shocks the patient automatically.


If there are a number of languages spoken on-site, a multi-lingual unit where you can change language at the touch of a button would be worth considering.


A child under the age of 8 requires a lower shock level than an adult. This is achieved by using paediatric electrode pads (available separately) or having a unit that can reduce the shock level using adult electrode pads through a switch/button/key, thereby reducing precious time to rescue.


All defibrillators have voice prompts, some also have visual prompts to guide the rescuer. This is particularly useful in noisy environments or where multiple languages are spoken.


Defibrillators require maintenance and replacement of consumables (pads & batteries). Pads and batteries with longer expiry dates have lower ongoing costs.


All units have an IP rating which grades the resistance of the defibrillator against the intrusion of dust or liquids. Depending on the environment the unit will be in, an IP rating may be an important factor.


All defibrillators guide rescuers with CPR rate, but those with a feedback feature will also analyse chest compressions and give live feedback making sure the rescuer provides the best quality CPR.


his is especially useful if you have a few defibrillators and need to monitor them remotely.


Defibrillators all perform self-testing on a weekly basis. A few units perform self-tests daily. Some defibrillator guardians prefer this peace-of-mind. Please note, there could be a negative effect on the overall battery life.


If your defibrillator is likely to be regularly transported or there is a high chance of it being carried from it's storage location to where it is needed, a carry case is recommended to protect it during transit.
