How to Use a Defibrillator (AED) – First Aid Training – St John Ambulance
An AED is a life saving device that can give your heart an electric shock when it has stopped in a cardiac arrest. AED is short for
‘Automated External Defibrillator’. An AED can be used on adults and children over 1
year old. Using an AED in crucial minutes before an ambulance arrives can increase
someone’s chance of survival. Anyone can use an AED. You don’t need to
be worried about getting it wrong or causing harm, because the machine
analyses the casualty’s heart’s rhythm and then gives visual or voice prompts to guide
you through each step. If someone is unresponsive and not
breathing normally, ask someone to call 999 or 112 for emergency help. Ask them to bring an AED if one is available. If you are alone, make the emergency call yourself on a mobile phone or on speakerphone and start CPR
with chest compressions. Do not leave the casualty to look for an AED. Keep doing CPR until someone brings an AED. As soon as the AED arrives, ask for it
to be switched on while CPR is continued. It will immediately start to give you a
series of visual and verbal prompts informing you of what needs to be done. If someone is with you, ask them to follow the instructions until emergency help
arrives. AED VOICE PROMPT: Call for help now. AED VOICE PROMPT: Remove all clothing from patient’s chest. AED VOICE PROMPT: Pull red handle to open bag. AED VOICE PROMPT: Look at pictures on pads. AED VOICE PROMPT: Peel one pad off blue plastic. AED VOICE PROMPT: Apply pad to bare skin
exactly as shown in the picture. AED VOICE PROMPT: Press pad firmly. Peel other pad off blue plastic. AED VOICE PROMPT: Apply pad to bare skin exactly as shown in the picture. AED VOICE PROMPT: Evaluating heart rhythm.
TRAINER: Stop compressions Susan, stand back. AED VOICE PROMPT: Stand by. Preparing to shock.
TRAINER: Stand clear everyone! AED VOICE PROMPT: Everyone clear. Do not touch patient. TRAINER: Stand back.
AED VOICE PROMPT: Delivering shock. *AED beeps* AED VOICE PROMPT: Shock delivered. Provide chest compressions and rescue breaths. The AED will instruct you to continue CPR for two minutes before it re-analyses. The AED could say ‘no shock advised, continue CPR’. If the casualty shows signs of becoming responsive, place them in the recovery
position. Leave the AED attached. Continue to follow the voice and/or visual
prompts that the machine gives you, until help arrives. So remember: when using an AED, call 999 or 112 for emergency help. Continue giving CPR when the AED arrives, and keep going while the pads are applied if possible. Ensure that the pads are placed on the chest after clothing has been cleared or cut away. Ask for the AED to be switched on and follow the instructions. Ask people to stand back when the AED is analysing and when any shocks are being delivered. And that’s how you use an AED.
