Every year, around 30,000 people in the UK will have an out of-hospital cardiac arrest. Resuscitation will be attempted by the ambulance service in a large number of cases. Less than 10% of these will survive.
What is an AED?
An AED, or automated external defibrillator, is used to help those experiencing sudden cardiac arrest. It's a sophisticated, yet easy-to-use, medical device that can analyze the heart's rhythm and, if necessary, deliver an electrical shock, or defibrillation, to help the heart re-establish an effective rhythm.
What the experts say:
British Heart Foundation and The Resuscitation Council (UK) state a cardiac arrest is when someone’s heart stops pumping blood around the body and they stop breathing normally. Without intervention, brain damage will begin to occur in around four minutes. After ten minutes, survival is extremely unlikely.
By administering an electric shock through the chest wall, using an AED is often the only way a person can recover from a cardiac arrest. This can be done in the ambulance, or at hospital, or it can be done by a member of the public at the scene of a cardiac arrest if there is an AED nearby.
Bystander Cardiopulmonary Resuscitation (CPR) and their use of an AED in the first few minutes can significantly improve the chance of survival. Defibrillation within three to five minutes can increase survival rates to 50-70%.
How the local communities are helping:
Community AEDs can be found both in small rural villages, as well as urban cities; in fact, they can be found just about anywhere there are people. They are funded by communities, sometimes with help from local and national charities.
Available to the public 24 hours a day. Usually placed on the outside of a building.
The AED will be stored in a locked cabinet (keypad operated) that keeps the unit above 5ºC to maintain the battery.
The keypad code to open the cabinet is recorded by the Ambulance Service Emergency Operations Centre (999).
In the event of a life-threatening emergency, an individual calling 999 will be advised if there is a community defibrillator within a 500m radius, given the code to open the cabinet, and asked if someone can retrieve it.
It is recommended that two community guardians are allocated to be responsible for checking both the cabinet and the AED on a weekly basis, and to arrange the unit to be reset post use.
Where there are concerns around security, it is suggested that locations are well lit and within sight of CCTV cameras.
Most cabinets are made of either steel or a tough polycarbonate compound, which make them very secure.
Privately owned AEDs:
Many businesses, schools and sports centres have defibrillators on their premises. These are often located inside secured premises and do not usually need a cabinet with a keypad lock. It is encouraged that businesses that own a defibrillator consider placing it in an external cabinet to open up availability, but it is understood this is not always suitable. If you can only make your AED accessible to the public during certain times, you can register this availability with the emergency services, the more they know about the more they can help.
The use AEDs for schools and colleges:
If you would like a private AED, the Department of Education (DoE) has a scheme where you can receive a discounted rate, specifically for schools and colleges. The DoE website will have the latest information on this. Alternatively, please get in touch to see if we can assist with a contribution from our community fund.
Do you need training:
The Resuscitation Council (UK) guidelines state that the use of defibrillators should NOT be restricted to trained personnel. AEDs can be safely used by untrained members of the public.
An AED will analyse the casualties heart rhythm and will only deliver a shock if the heart needs it, you cannot hurt someone by using it. Being aware that you can use a defibrillator and that it is easy and safe to do so, can speed up the time between turning the machine on and the first shock being delivered, if required. We are happy to offer a free, two-hour familiarisation session, for those purchasing a community AED, and for a small charge we can offer this to those purchasing AEDs for private/workplace use.
Are there any legal concerns:
The likelihood of causing harm by performing CPR or using an AED is very small. At this time, we are not aware of any reported successful claims in the UK against a rescuer attempting to resuscitate someone having a suspected cardiac arrest. The Resuscitation Council (UK), who are responsible for developing and publishing evidence-based resuscitation guidelines in the UK, have published a user’s guide if you wish to understand more: www.resus.org.uk/cpr/cpr-aeds-andthe-law
