An Automatic External Defibrillator (AED) machine is a life-saving device used to treat individuals experiencing sudden cardiac arrest. It is designed to quickly analyse the heart's rhythm and, if necessary, deliver an electrical shock, or defibrillation, to help the heart re-establish an effective rhythm. This portable device is crucial in emergency situations and is engineered to be used by people with minimal medical training. The AED's simplicity and voice prompts assist the rescuer in taking prompt and accurate action during a critical situation.
AEDs are essential in emergency medical situations where immediate intervention is critical to patient survival. Due to their high cost, AEDs are often included in medical equipment loan programs that allow healthcare providers and public venues to have access to these crucial devices without incurring the full upfront cost. These programs can significantly enhance public safety by broadening the availability of AEDs in community spaces, thereby increasing the chances of survival following sudden cardiac events.

Why are AEDs important?
Automated External Defibrillators (AEDs) are crucial life-saving devices that play a pivotal role in emergency situations, particularly when someone experiences sudden cardiac arrest. AEDs are important because they deliver a controlled electric shock to the heart, effectively restoring its normal rhythm in cases of irregular heartbeat or cardiac arrhythmia. Time is of the essence during a cardiac emergency, and AEDs are designed to be user-friendly, enabling even untrained individuals to administer potentially life-saving treatment until professional medical help arrives. Their widespread availability in public spaces, workplaces, and homes significantly increases the chances of survival for individuals experiencing cardiac arrest, making AEDs indispensable tools in safeguarding communities against the devastating consequences of sudden cardiac events.
Different types of AEDs
There are several types of Automatic External Defibrillators (AEDs) available, each designed for specific environments and uses. These include fully automatic and semi-automatic models, as well as those tailored for hospital or public use. Some AEDs are equipped with features like paediatric pads for children, and others are more rugged and water-resistant for outdoor use. The choice of an AED model typically depends on the user’s specific needs for accessibility, ease of use, and the physical conditions under which the device might be employed.

How does AED machine work
- Analysis: Automatically assesses the patient’s heart rhythm.
- Decision: Determines if a shock is necessary.
- Shock delivery: Administers an electric shock through the chest wall to the heart.
- Guidance: Provides step-by-step voice instructions to the rescuer.
How to use an AED?
- Assess the situation: Ensure the area is safe for both the rescuer and the victim.
- Check responsiveness: Gently shake the person and shout to see if they respond.
- Call for help: Dial emergency services and ask for assistance, mentioning the need for an AED.
- Open the AED: Turn it on and follow the voice prompts or on-screen instructions.
- Prepare the chest: Remove clothing and ensure the chest is dry and free of hair if possible.
- Attach pads: Place the adhesive pads on the victim’s bare chest as shown in the diagrams.
- Analyze rhythm: Allow the AED to analyse the heart rhythm without touching the victim.
- Deliver shock: If instructed, ensure no one is touching the victim and press the shock button.
- Continue CPR: Follow the AED prompts and continue CPR until emergency personnel arrive or the victim shows signs of life.
When to use an AED?
An AED should be used when someone is experiencing sudden cardiac arrest (SCA). Signs of SCA include sudden collapse, lack of responsiveness, and absence of normal breathing. If you encounter a person showing these symptoms, immediately call emergency services and start CPR. Use the AED as soon as it is available. The device is designed to analyse the heart's rhythm and deliver a shock if necessary to restore a normal heartbeat. Early defibrillation, combined with CPR, greatly increases the chances of survival. AEDs are suitable for use on adults and children over one year old, with pediatric pads used for younger children if available.
When not to use an AED?
An AED should not be used in certain situations. Do not use an AED if the person is conscious and breathing normally. Avoid using an AED on a person with a steady pulse or if they are showing signs of life. Do not use the device in a wet environment or if the person is lying in water. Ensure the chest is dry before applying the pads. Avoid placing AED pads over a pacemaker or implanted defibrillator. Do not use an AED on infants under one year old unless the device has specific pediatric settings. Always follow the AED's instructions and ensure a safe environment before delivering a shock.
Where is an AED used?
- Public spaces: Airports, shopping malls, and sports arenas where large crowds gather.
- Educational institutions: Schools and universities to provide immediate aid.
- Workplaces: Offices and factories equipped to handle medical emergencies.
- Transport hubs: Train stations and bus terminals to assist in passenger emergencies.
Who can use an AED?
An Automated External Defibrillator (AED) is designed to be user-friendly and can be operated by anyone, regardless of medical training. In emergency situations such as sudden cardiac arrest, time is critical, and AEDs are designed to be quickly accessible and simple to use. While medical professionals are trained in the use of AEDs, they are also intended for use by laypeople, including bystanders and non-medical personnel. Clear and concise instructions are provided with each AED, guiding users through the process step by step, from turning on the device to delivering the necessary shock. By empowering individuals with the ability to respond promptly to cardiac emergencies, AEDs significantly increase the chances of survival for those experiencing sudden cardiac arrest.
Do AED machines expire?
AED machines themselves do not expire, but their critical components, such as batteries and electrode pads, have expiration dates and must be regularly replaced according to the manufacturer’s guidelines. This maintenance is essential to ensure the device is ready to operate correctly when needed. The typical shelf life of these consumable parts ranges from two to five years, depending on usage and storage conditions.
How to choose an AED machine?
- Ease of use: Opt for devices with clear instructions and automatic functions.
- Durability: Consider the environmental conditions where the AED will be stored.
- Maintenance: Check the ease of maintenance and availability of replacement parts.
- Cost: Budget for initial purchase and ongoing maintenance costs.
