Defibrillators

Find your nearest defibrillator here

A defibrillator is a device that gives a high energy electric shock to the heart of someone who is in cardiac arrest. This high energy shock is called defibrillation, and is an essential part in trying to save the life of someone who is in cardiac arrest. A defibrillator may also be called a defib, an AED (Automated External Defibrillator) or a PAD (Public Access Defibrillator).

A defibrillator should be used when a person is in cardiac arrest. CPR should be carried out until you can gain access to a defibrillator.

If you see someone going into cardiac arrest, call 999, start CPR and locate someone to find a defibrillator. The emergency operator will advise you of your nearest defibrillator. Once you have the defibrillator, turn it on and continue CPR until the device tells you to stop.

How to use a defibrillator

If you are on your own, do NOT interrupt CPR to go to find a defibrillator. If it is possible, send someone else to find one. When you call 999, the operator can tell you if there is a public access defibrillator nearby.

To use a defibrillator, follow these simple steps:

Step 1: Turn the defibrillator on by pressing the green button and follow its instructions.

Step 2: Peel off the sticky pads and attach them to the patient’s skin, one on each side of the chest, as shown in the picture on the defibrillator.

Step 3: Once the pads have been attached, stop CPR and do NOT touch the patient. The defibrillator will then check the patient’s heart rhythm.

Step 4: The defibrillator will decide whether a shock is needed and if so, it will tell you to press the shock button. An automatic defibrillator will shock the patient without prompt. Do NOT touch the patient while they are being shocked.

Step 5: The defibrillator will tell you when the shock has been delivered and whether you need to continue CPR.

Step 6: Continue with chest compressions until the patient shows signs of life or the defibrillator tells you to stop so it can analyse the heartbeat again.

Anyone can use a defibrillator and you do not need training. Once you turn it on, it will give clear instructions on how to attach the defibrillator pads. The device checks the heart rhythm and will only tell you to shock if it’s needed. You cannot shock someone accidentally.
