Automated external defibrillator (AED)

Decorative image onlyPublic access defibrillators (PADs) can be found in public spaces for example, community centres, shopping centres or train stations etc.

If someone has a cardiac arrest away from hospital, having a defibrillator close at hand can be of assistance in the lifesaving steps towards survival. The device creates an electric charge to shock the heart and help to establish a normal heartbeat, this is called defibrillation.

If you find yourself in this situation, in the first instance you should always call the emergency services on 999 and ask for the Ambulance service and be guided by them.

Listed below are some useful resource websites that we are aware of that has a list of known AED locations and information about how to register your defibrillator.

South Central Ambulance
