Defibrillators

A defibrillator is a device used to give a patient an electric charge to the chest to restore the natural rhythm of the heart. Normal rhythm can stop in the event of a heart attack, or cardiac arrest, and a defibrillator usually helps to start the heart beating again. Along with CPR, a defibrillator is the standard way to save someone’s life with first aid.

How to use a defibrillator

  • If you find someone who is unresponsive and not breathing, ask someone to call 111 and fetch your defibrillator. If you have a hands free phone, call 111 yourself and ask for the ambulance service. Don’t leave the patient to find a defibrillator if you don’t have help, as you should begin CPR.
  • Once you have a defibrillator, ask your helper to switch it on and prepare the pads while you continue CPR. Remove the patient’s clothing to expose the chest. Dry the chest if possible.
  • Many defibrillators provide voice prompts. Follow these prompts. Attach the pads to the chest, one on the upper right side below the collar bone, the other on the left side below the armpit.
  • Allow the defibrillator to analyse the patient’s heart. When it is ready to apply the charge, stop CPR, stand back and do not touch the patient. Follow the instructions for when to press the shock button.
  • Once complete, continue CPR. Continue to follow the prompts from the defibrillator if a second shock is necessary. If your patient becomes responsive, put them into the recovery position lying on their side with their upper leg folded upward for support.
