Why Every Workplace and Public Space Needs an AED
Sudden cardiac arrest (SCA) can happen to anyone, anywhere, at any time. In the UK, there are approximately 30,000 out-of-hospital cardiac arrests each year. For every minute without defibrillation, the chance of survival drops by 7–10%. An automated external defibrillator (AED) can restore a normal heart rhythm within moments, dramatically improving survival rates from under 5% to over 70% when used within the first few minutes.
Since 2022, the UK government has been rolling out defibrillators to all state-funded schools in England. But it's not just schools — offices, gyms, sports clubs, churches, village halls, and any public gathering place should have easy access to an AED.
Fully Automatic vs Semi-Automatic AEDs: What's the Difference?
The main choice you'll face when buying a defibrillator is whether to go fully automatic or semi-automatic.
Fully Automatic AEDs
A fully automatic AED analyses the heart rhythm and delivers a shock automatically — no button press required. This makes it ideal for locations where untrained bystanders are most likely to use the device, such as shopping centres, offices, and public buildings. Models like the Stryker Lifepak CR2 Fully Automatic and the ZOLL AED Plus Fully Automatic fall into this category.
Semi-Automatic AEDs
A semi-automatic AED analyses the rhythm and then prompts the user to press a shock button. This gives trained first aiders a moment to ensure everyone is clear before the shock is delivered. Many organisations prefer semi-automatic models for trained workplace first aid teams.
Key Features to Look For
1. Clear Voice and Visual Prompts
Every modern AED provides step-by-step voice instructions. Look for devices with loud, clear audio and visual diagrams — especially important in noisy environments. The ViVest PowerBeat X1 is particularly well-regarded for its intuitive user guidance.
2. CPR Feedback
Some AEDs, like the ZOLL AED Plus, provide real-time CPR feedback — coaching the rescuer on compression depth and rate. This feature can significantly improve the quality of CPR delivered alongside defibrillation.
3. Paediatric Capability
If your AED may be used on children (under 8 years or 25kg), ensure it has a paediatric mode or separate paediatric electrode pads. Schools should prioritise models with easy-switch paediatric capability.
4. Battery Life and Pad Expiry
AEDs sit idle for months or years between uses, so long battery life and pad shelf-life matter. Look for devices with 4–5 year pad life and battery standby of at least 4 years to minimise ongoing costs.
5. Durability and IP Rating
For outdoor installations or harsh environments, check the AED's IP (Ingress Protection) rating. A higher rating means better protection against dust and water.
UK Regulations and Guidelines
While there is no legal requirement for most private businesses to have a defibrillator, the Resuscitation Council UK strongly recommends public access defibrillation programmes. Schools in England are now required to have AEDs. The Health and Safety Executive (HSE) considers AEDs as part of good first aid provision in the workplace.
Importantly, you do not need formal training to use an AED. The devices are specifically designed for use by members of the public with no medical training. However, training is recommended and builds confidence.
