Fully Automatic Defibrillators
Sudden cardiac arrest can happen at any time without indication. Each minute someone suffering a cardiac arrest is left untreated the chances of the sufferer surviving decrease by 10 percent. Having an easy to access and easy to operate defibrillator available will save lives.
A fully automatic defibrillator will measure the sufferer's heart rate once the paddles are attached and if the unit detects an irregular heartbeat it will charge and deliver a life-saving shock without the need for input from the first-aider. Once the shock is delivered the unit will indicate that the first-aider can begin CPR. Semi-automatic AEDs are also available, as well as accessories such as cabinets for storage and ease of access, AED Prep Kit to prepare patients for defibrillation and bundle packages that provide an AED along with informational signage, a cabinet and training materials.

Why Should I Install a Defibrillator on My Premises?
A sudden cardiac arrest (SCA) can happen anywhere, at any time, and without immediate treatment, survival rates drop dramatically. A defibrillator (AED) provides a lifesaving shock to restore normal heart rhythm, significantly increasing survival chances.
Key Reasons to Have a Defibrillator On-Site:
Cardiac Arrest Can Happen to Anyone
It’s not just older individuals or those with known heart conditions; SCA can strike anyone, at any age, including healthy adults and young people.
User-Friendly Design
Modern defibrillators give clear voice and visual instructions, making them easy for anyone to use, even without medical training.
Time is Critical
Survival rates drop by 10% every minute without defibrillation. Having an AED on-site allows treatment to begin immediately, rather than waiting for emergency services.
Legal and Moral Responsibility
Employers and facility managers have a duty of care to protect staff, customers, and visitors. A defibrillator demonstrates proactive safety measures.
Improves Survival Rates
Using a defibrillator within the first few minutes of cardiac arrest can increase survival rates to over 70%.
How Do Defibrillators Work?
Automated External Defibrillators (AEDs) are lifesaving devices that deliver an electric shock to a person in sudden cardiac arrest (SCA), helping restore a normal heart rhythm.
How an AED Works:
- Voice-Guided Instructions – AEDs provide clear audio prompts, allowing anyone to use them, even without prior training.
- Heart Rhythm Analysis – Once electrode pads are attached to the chest, the AED automatically detects if a shock is needed.
- Shock Delivery (If Required) – The AED will only administer a shock if necessary.
-
Semi-Automatic AEDs require the user to press a button to deliver the shock.
-
Fully Automatic AEDs deliver the shock automatically after a warning and countdown.
-
- How the Shock Helps – The shock pauses the heart's chaotic rhythm, allowing it to reset and hopefully return to a normal beat.
Why Early Defibrillation Matters
- Every minute counts – Survival chances drop by 10% per minute without defibrillation.
- Using an AED within 3–5 minutes of collapse offers the best chance of survival.
- While not every case of SCA is survivable, early defibrillation dramatically improves outcomes.
Having an AED readily available can mean the difference between life and death in an emergency.
Semi-automatic defibrillators (AEDs) are life-saving devices that require the user to press a button to deliver a shock when prompted. They are designed to be easy to use while ensuring the rescuer remains in control.
Key Benefits:
- More control for the rescuer – The shock is only delivered when the user confirms it’s safe to do so.
- Clear audio instructions – Guides the user step-by-step, making it easy for anyone to operate.
- Reliable and effective – Only delivers a shock if the heart is in a shockable rhythm.
Fully-automatic defibrillators (AEDs) are designed to deliver a shock without the need for user intervention, making them ideal for untrained responders in high-pressure situations.
Key Benefits:
- No button to press – Reduces hesitation and speeds up treatment.
- Ideal for public use – Provides fully guided assistance, making it easier for untrained users.
- Fast response – Ensures the shock is delivered as quickly as possible without delay.
Where Should Defibrillators Be Located?
Ensuring a defibrillator (AED) is placed in the right location can save lives. It should be easy to find, clearly signed, and accessible in an emergency.
1. Publicly Accessible Locations
- AEDs should be installed in high-traffic areas where cardiac arrests are more likely to occur
- Common locations include offices, schools, gyms, shopping centres, train stations, sports venues, and community spaces
- For outdoor locations, use a weatherproof, heated AED cabinet to keep the device protected and functional
Publicly accessible defibrillators make a real difference in survival rates. By placing AEDs in open, well-signposted locations, organisations maximise their impact and help save lives within the immediate community.
2. Clear and Visible Signage
- The AED cabinet must be clearly labelled with "Defibrillator" or "AED" and the universal heart symbol.
- Additional signage should be placed above the cabinet (e.g., mounted on a wall or post) to ensure visibility, even if obstacles like parked vehicles block the view.
- Raise awareness by adding AED location signs in nearby businesses or public areas to help people locate it in an emergency.
3. Informing the Ambulance Service
- Register your AED with The Circuit (thecircuit.uk) – the UK’s national defibrillator network.
- This ensures 999 and 112 operators can direct bystanders to the nearest available AED when responding to an emergency.
- Provide details such as the AED location, cabinet access code (if locked), and AED model to ensure responders can access and use it effectively.
Proper placement, clear signage, and emergency service registration make an AED more effective in a life-threatening situation. Ensure your device is easy to find, easy to access, and known to local emergency services.
How Should Defibrillators Be Stored?
Proper storage ensures a defibrillator (AED) remains fully functional and accessible in an emergency. The right cabinet depends on location, security, and environmental conditions.
Indoor vs. Outdoor Storage:
Indoor cabinets
Suitable for controlled environments but must not be used outdoors.
Outdoor AEDs
Need weatherproof, temperature-controlled cabinets to prevent battery damage.
Outdoor AED Cabinet Considerations:
Temperature Control
- AEDs function between 0–50°C and must stay above freezing.
- Heated cabinets prevent freezing, while ventilated cabinets reduce overheating.
Security & Access
- Open access is recommended by the UK Resuscitation Council to prevent delays.
- Keypad entry is an option if security is a concern—avoid key-locked cabinets.
Visibility & Awareness
- Clear signage and good lighting ensure the AED is visible, even at night.
Power Supply
- Plug-in cabinets are easy to install but risk being switched off.
- Hardwired options are more reliable but require professional installation.
- Solar-powered cabinets work well in remote locations with sufficient sunlight.
Weather Resistance & Construction
- IP-rated cabinets protect against dust and water—higher ratings offer better protection.
- Stainless steel is the most durable, while plastic cabinets are lightweight and corrosion-resistant.
Choosing the Right Storage Solution
Select an easily accessible, well-protected AED cabinet suited to your environment. Proper placement ensures the AED is always ready when needed.
Defibrillator Accessories, Inspection, and Maintenance
To ensure a defibrillator (AED) is always ready for use, regular maintenance and timely replacement of essential accessories are crucial.
Batteries
- AED batteries have a standby life of 2–5 years, depending on the model.
- Regularly check battery status indicators and replace before expiry to avoid failure in an emergency.
Pads (Electrodes)
- AED pads expire after 2–5 years and must be replaced once used.
- Some models have child-specific pads or a child key/switch to adjust energy levels for paediatric use.
Regular Maintenance Checks
- Perform routine inspections to ensure the AED is fully operational.
- Check:
- Battery and pad expiry dates
- Status indicator (most AEDs have a light or screen showing readiness)
- Casing and accessories for damage
- Store in a visible, accessible location and ensure all staff know how to use it.
A well-maintained AED ensures fast, reliable response in a cardiac emergency.
