How to choose the right defibrillator

When purchasing an automated external defibrillator it’s important that you buy one that will meet your needs.

For example; if you intend to use your AED in a harsh environment such as a farm, outdoors or in a swimming pool then you need a robust AED with a high IP rating. IP rating stands for ingress protection and each AED we sell is tested to check if it will withstand contact with water and dust.

Ingress protection rating (IP) – is the measurement that shows the degree of environmental protection an AED has from dust and water. The higher the IP rating of an AED shows that it is better protected against dust and water.

Drop abuse test – is the height the device can be dropped on to a concrete surface and still be able to function.

Warranty – most manufacturers offer a warranty on the AED of typically 5-10 years. Please note that the warranty given for electrodes, batteries and accessories supplied with your AED are shorter.

Ease of use – all modern AEDs are simple and easy to use however some have features such as real CPRD help. This is a feature currently only available on the ZOLL AED 3ZOLL AED Plus and the Cardiac Science G5 CPRD versions. All of these devices give live CPR feedback to the rescuer during cycles of CPR to essentially coach you into giving better quality CPR.

Running cost – it always makes sense to check the cost of replacement batteries and electrode pads before purchasing a new defibrillator as the running costs can vary from one model to another. Also check the standby life as they can typically range from 2-5years.

Total cost of ownership – as a rough guide add together the purchase price of your defibrillator, accessories and then the replacement pads and batteries it will require over a 10 year period and divide by 10. You will be quite surprised that the cheapest defibrillator can work out more expensive than a premium brand to own as consumables generally require replacing more frequently.
