When someone experiences sudden cardiac arrest knowing how to act quickly can make all the difference. Automated External Defibrillators (AEDs) are designed to be easy to use even if you’ve not previously had first aid training or are not a medical professional.
This guide will take you step-by-step through using an AED effectively in an emergency so you feel prepared to help in such a vital situation.
What is an AED and Why Use One?
An AED or Automated External Defibrillator is a portable device that can help restore a normal heart rhythm in someone experiencing sudden cardiac arrest. By delivering a controlled electrical shock it helps to “restart” the heart’s rhythm. AEDs are designed with clear instructions to guide you step-by-step so anyone even those with minimal or no medical background can potentially save a life
7 Steps for Using an AED
Step 1: Check for Responsiveness and Call for Help
Start by making sure the scene is safe to approach, then check if the person is responsive by tapping their shoulder and asking loudly, “Are you okay?” If there’s no response call for help. Ask someone nearby to call 999 and bring an AED if one is accessible. If you’re alone call 999 yourself and follow any guidance the call operator provides while you wait for help.
Step 2: Begin Chest Compressions
If the person isn’t breathing or is only gasping start chest compressions right away. Place the heel of one hand on the centre of their chest, put your other hand on top interlocking the fingers, and press down hard and fast. Aim for 100-120 compressions per minute, pressing about 5-6 cm (2 inches) deep. These compressions help keep blood flowing to the brain and vital organs until the AED can be used.
Step 3: Turn On the AED and Listen to Instructions
Once the AED arrives turn it on immediately. Most AEDs will start giving you clear, spoken instructions to guide you. Just listen and follow each prompt—it’s designed to walk you through each step.
Step 4: Attach the Pads to the Person’s Chest
Inside the AED package, you’ll find two adhesive pads. Remove the backing and place the pads on the person’s bare chest as shown on each pad. Generally, one pad goes on the upper right side of the chest below the collarbone and the other on the lower left rib. Proper placement is essential for the AED to work correctly.
Step 5: Let the AED Analyse the Heart Rhythm
Once the pads are in place the AED will automatically analyse the person’s heart rhythm. Make sure no one is touching the person while this happens as movement can interfere with the reading. The AED will assess the heart rhythm and let you know if a shock is needed.
Step 6: Deliver a Shock if Advised
If the AED advises a shock make sure everyone is clear of the person. Say “Clear!” loudly to ensure no one is touching the patient then press the shock button as instructed. The AED will deliver an electric shock to try to reset the heart’s rhythm which can make a crucial difference in their chances of survival. Note some AED models are designed to automatically provide a shock eliminating the need to press the shock button.
Step 7: Continue CPR and Follow AED Prompts
After the shock is delivered the AED will prompt you to continue CPR. Follow the AED’s instructions as it will keep monitoring the heart and let you know if additional shocks are necessary. Continue until emergency responders arrive and take over or until the person shows signs of recovery.

FAQs About AED Use
Using an AED involves:
● Checking for a response
● Calling for help
● Starting chest compressions
● Turning on the AED
● Attaching the electrode pads
● Analysing the heart rhythm
● Delivering a shock (if advised) and continuing CPR
If the AED is immediately available, use it as soon as possible. However, if there’s a delay, start CPR right away to maintain circulation until the AED is available and ready.
No, if there’s a pulse you don’t need an AED. AEDs are used when the heart stops effectively pumping blood. Always monitor for a pulse and breathing before you use the device.
There are situations where an AED isn’t appropriate, such as if the person is breathing and has a pulse. Avoid using an AED in wet conditions, as water conducts electricity, posing a safety risk. Make sure the person’s chest is dry and avoid placing the pads over any devices under the skin like a pacemaker.
Yes, AEDs are designed to guide you throughout. If it doesn’t detect a shockable rhythm it will prompt you to keep doing CPR. After each cycle, the AED will recheck the heart rhythm and instruct you accordingly.
A common mistake is pressing too lightly or slowly on the chest. Effective CPR should be quick (100-120 compressions per minute) and deep (about 2 inches). Another mistake is not allowing the chest to rise fully between compressions reducing the effectiveness of CPR.
If the AED says “no shock advised,” check for breathing or a response. Continue with CPR if the casualty is not breathing and not responding. The device will continue to check the heart’s rhythm and guide you as needed. Continue until professional help arrives.
