AED Checklist Tag

When you receive your defibrillator from us, you will find in the box an AED Service Log, similar to the one in the image below.

About the Service Log and what you should do with it.

You should enter the details of your defibrillator, with a permanent marker pen, on the reverse of the card.  If you have any problems in the future, need replacement electrodes or battery or have deployed your defib, completion of this tag will ensure that you always have all of the information to hand and in one place, when you need to contact us.

The tag should also be used to record your annual defibrillator services, to ensure that you conform with current legislations and always have your defibrillator rescue-ready.

aed check 1

Every defibrillator comes with electrodes and a longlife battery, both of which require periodic replacement at the end of their lifecycle.  To ensure that your defib is functioning correctly and always ready to be deployed,  the following should be checked weekly:

- Shelf life of electrodes (also referred to as pads)

The electrodes do not last as long as the AED. Typically their lifecycle averages at around 2 years. The expiry date can be found on the packaging of the electrodes. Towards the end of their lifecycle, electrode pads become less conductive, reducing their ability to provide a lifesaving shock and in some cases the defib will not register the correct attachment of the electrodes and therefore not issue a shock when needed.  The same applies to electrodes where the packaging has been opened or tampered with.  Good electrodes are of vital importance to the defibrillato and must be replaced just before their expiry date, after every use or if the packaging has been opened!

It is important that the packaging remains intact & sterile. An opened package can cause the electrode's conductive gel to dry up, as well as become a breeding ground for dirt and bacteria.

- Sustainability of paediatric pads

Often paediatric electrodes have a shorter lifecycle than adult electrodes, therefore these may need replacing earlier and more frequently than adult electrodes.

- Is the AEDs status indicator displaying 'ok' or green? 

All defibrillators perform regular self-tests to check for any malfunctions. The AED’s indicator light will flash or you may  see a green light or a green tick. This will indicate that a self-test was successful.  The status indicator of your AED should be checked daily.  If the status indicator is displaying a fault, this means that it will not function if needed.  This is more often than not because your electrodes and/or battery are due to expire, or it could be a more serious fault.  You should contact us immediately if you are not able to rectify the problem.

- Rescue Kit

Every AED that we sell is provided with a free Rescue Kit.  This kit contains everything you may need during a resuscitation. These items include a pair of clothing scissors, razor, sterile wipes, gloves, cloth and an oxygen mask with O2 adaptor.  This rescue kit can be attached to your AED so it is always stored and transported with the AED.

aed check 2

The serial number of the AED can be found on the back of the device, along with the make and model information.

Data storage life of the electrodes and batteries;

Please always update these on your tag when changed. The lifecycle of the electrodes is shown on the electrodes themselves.
The shelf life of the batteries is not usually on the battery. In most cases, the date shown on the battery is the date of manufacture or a use-by date . The lifecycle of the battery begins after first insertion of the battery and varies depending on the make/model of AED.  Details of the battery lifespan for your AED can be found in the user manual or on our website.

Below you will see some typical images for some of the AEDs that we stock.  A tick shows a date that you can fill out on the card.  A cross indicates where you must calculate the expiration date yourself, which is calculated  from the date that it was connected to the defibrillator.

Cardiac Science Powerheart

The Cardiac Science battery has a five year lifespan from the initial insertion into the AED . This battery comes with a 4 year unconditional warranty.

Defibtech Lifeline

The yellow battery with model number DCF -210 has a lifecycle of approximately 5 years after initial insertion into the AED. Please note that the Defibtech battery also has a 7 year version.  The yellow battery also has a lithium 9V block battery, used for self-tests, this 9V battery has a lifecycle of approximately 1 year.

HeartSine Samaritan

This AED is unique in that it is designed with the electrode and battery as 1 unit. The lifecycle is around  3 1/2 - 4 years after initial insertion into the AED but will need to be completely replaced if the defibrillator is used..

GE Responder

Physio-control lifepak 500 battery standby-life physio-control lifepak 1000 battery standby life

The batteries for the Lifepak 500 and Lifepak 1000 have a 5 year lifespan after initial insertion into the AED.

Philips HeartStart

The lifespan of the battery for the Philips HS1 and FRx defibrillators is 4 years from initial insertion into the AED.

Zoll AED

Zoll AED Plus defib pads shelf life Zoll AED Plus batteries (roll of 10) standby-life

Batteries for  the Zoll AED Plus last around 5 years from initial insertion into the AED.

It is worth noting that deployment of your defibrillator will deplete batteries faster than their indicated lifespan.  Storage of the defib in the extreme cold will also deplete a battery faster.  If your AED is stored in a cold location or outside in a car or even in a special outdoor AED cabinet, it should be moved to a warmer location during periods of extreme cold weather conditions.  Likewise at times of extreme hot weather conditions, a defibrillator should be temporarily moved to a cooler location.

The lifespan of the batteries factors in the regular self-checks that the AED performs, if the user performs additional manual self-checks, this will quickly deplete the battery.

Electrode pads are single use and need to be changed after every use, if they reach their expiry date or if the outer packaging has been damaged or opened.  The conductive gel begins to corrode on contact with the air and over time, this could result in the defibrillator not recognising that the electrodes are attached to the patient, which would result in the defibrillator not producing a shock if needed.
