Using a defibrillator

Do you have to be trained to use a defibrillator?

No – the defibrillator will guide you through what to do with simple voice instructions and visual prompts. However, we would encourage everyone to take defibrillator training to ensure they are familiar with the device and ready to act confidently in an emergency.

Anyone can safely use a defibrillator. Do not wait for the emergency services to arrive to start treating the casualty.

Different casualty scenarios

Can defibrillators be used on children?

Yes, standard defibrillator pads are suitable for use on children over the age of eight.

For children aged between one and eight years, use a paediatric defibrillator or standard defibrillator with paediatric pads. The paediatric pads adjust the current delivered during defibrillation. In an emergency, if a defibrillator with adult pads is the only device available, then it can be used.

Never use a defibrillator on infants under the age of one.

Can defibrillators be used on pregnant women?

What if the casualty has a pacemaker or implantable cardioverter defibrillator (ICD)?

What about medication patches?

Can a defibrillator be used if it is wet or raining?

Things you may need to do as a rescuer

Will I need to remove the casualty’s clothes?

Any clothing or jewellery that could interfere with the pads should be removed or cut away, as the pads must be attached to bare skin. You will also need to remove clothing containing metal from the area where the pads are attached, such as an underwired bra.

Do I have to shave the casualty’s chest?

Technical questions

What’s the difference between an automatic and semi-automatic defibrillator?

An automatic defibrillator will deliver a shock automatically. Semi-automatic defibrillators require the rescuer to push a button to deliver a shock.

Some defibrillators have a manual override, which allows the user to initiate a charge and shock without first analysing the heart rhythm. These defibrillators are typically used by emergency responders, paramedics, and advanced life support professionals.

Is there a memory chip inside the defibrillator and if so what does it record?
