Steps to using a defibrillator


  1. Be sure that BOTH you and the patient are in a safe location before continuing. If an AED is available, also check to ensure that the patient is not in standing water and is not located near flammable materials. Do not make yourself another patient!



  2. Check the patient. Tap the patients shoulders ideally on the breast bone and shout at them.
  3. If there is no response, appoint someone to call 999 or 112 if no-one is available the do it yourself first
  4. Check the ABCs.

    • A-(Airway). Give two rescue breaths. Is the patient's airway clear? If not, it must be cleared by performing chest compressions and finger sweeps in the patient's mouth (only if an object is visible) before continuing with any type of care
    • B-(Breathing). Look, listen, and feel for breathing like this for no more than 10 seconds.
    • C-(Circulation). A patient in Cardiac arrest (full arrest, or cardioplumary arrest) has no pulse and is not breathing. Pulse checks takes time and are unreliable under the stress you will be feeling. If the victim is not breathing and not responding -- just start and continue with CPR.

Using the AED

  1. Look around your immediate area for an AED(Automated External Defibrillator)

  2. If you cannot locate an AED, proceed with CPR. You should instruct bystanders to call emergency services and search for an AED. Staff members in public places such as railway stations or airports will be able to provide instructions and alert any emergency response units or first aid teams that may be present to assist with CPR and Defibrillation.
  3. Turn on the AED unit. Depending on the model of the AED you may have to pull a handle or push the on button.
  4. 4
    Follow the AED's voice prompts.
  5. Remove all clothing from the chest, abdomen, and arms (male or female).
  6. Peel the pads off and place them exactly as shown. Accuracy is more important than speed when placing pads.
  7. Usually the AED will start to immediately analyze the patient's heart rhythm. Do not touch the patient during this or any other part of the defibrillation process.
  8. If the AED has a shock advised prompt, push the button. When you shock, make sure no one is touching the patient. Also, the patient must not be touching metal and there must not be large amounts of water on the chest (sweat is okay). The patient must not be wearing a nitro patch. If the patient has a pacemaker, try not to place the pads directly on the unit, switch sides and keep pads diagonally placed across the chest.
    • If the AED does not advise a shock, check the pulse, and if there is none, continue CPR.
