Need help? Need help? Don’t buy an AED until you’ve read our buyers guide! Expert Guidance, Top-Rated UK Defibrillators with Fast Delivery

Defibrillators are devices that give an electric shock to the heart of someone who is in cardiac arrest. Cardiac arrest is a common problem in the UK, with thousands of victims a year, making it highly likely an incident might occur in your workplace. They are not required by law to be fitted in workplaces, but they increase the likelihood of survival if a worker or visitor goes into cardiac arrest. According to the Resuscitation Council UK, defibrillation within 3–5 min of collapse can produce survival rates as high as 50–70%. Defibrillators have also changed and improved a great deal in the past few years, and they are now easier to use, all modern AEDs can be used with no prior knowledge or training.

Defibrillator Expert Advice and Help

What does AED stand for?

AED stands for Automated External Defibrillator.

“When confronted with a cardiac arrest emergency it’s important to remember that a prompt response is critical. A victim’s chances of survival decline by 10% for every minute that defibrillation is delayed! By contrast, using a defibrillator prior to any other life saving measures can increase survival rates by as much as 75%.Andrew Pear - CEO Reliance Medical

Why you should buy an AED for your workplace?

In the UK each year, there are more than 30,000 out-of-hospital cardiac arrests.

If CPR and defibrillation does not occur, every minute that goes by reduces the person's chance of living by 10%. However, as shown in the graph below if CPR and an AED is used the probability of survival is 24% higher.

This shows the importance of a defibrillator. Although it is an investment, a defibrillator will not need to be replaced once bought. It is one piece of equipment that could save a person’s life.

Although the law does not require defibrillators to be fitted, they are a wise investment for offices, as well as schools, nurseries, train stations and other public areas such as gyms, cinemas, theatres, doctor’s and dental surgeries. When it comes to health and safety, you can never be too careful, and a defibrillator could save the life of an individual suffering a cardiac arrest. Make sure to buy a defibrillator for your workplace today.

How does a defibrillator work?

When a person goes into cardiac arrest their heartbeat becomes irregular, so an AED sends out a high energy shock to try and restart the heart’s regular rhythm. This is called defibrillation. If this procedure is carried out within a few minutes the person has better chances of survival.

How to use a defibrillator?

Using a Zoll AED

Watch the video to see how easy it is to use the Zoll AED 3:

Also, this video shows how to use our Mediana Heart on Defibrillator to give you a guide on what you should do if you see someone in cardiac arrest. This is a similar process that can be followed with all of our defibrillator brands.

To use an AED, you first need to recognise that a person has collapsed and that it may be due to cardiac arrest. Then you should attach the two adhesive pads to the bare chest of the victim. Most AED’s come with audible step-by-step instructions on how to use the machine when they are needed.

Can use of an AED damage a casualty or make symptoms worse?

Defibrillators detect heart rhythms and will only deliver a shock if it is needed, therefore it's impossible to use an AED incorrectly.

How to choose an AED?

Like the rest of our first aid supplies, our range of defibrillators will help ensure your workplace is as safe as possible for workers and visitors. Defibrillators can mean the difference between life and death, and as they are now even easier to use there really is no excuse not to have one in the workplace.

Paediatric Mode

When using an AED on a child between 1 and 8 years it is recommended to use a reduced shock where possible. Some defibrillators require the electrode pads to be changed to specific ones for child use, whereas others can attenuate the shock simply by pressing a button or switch.

AED Batteries

How long does a defibrillator battery last? As you can see from the table above, this can vary depending on the type of AED, but most last 2-5 years. The battery should be checked routinely regardless of the expiration date to ensure the defib is ready for an emergency at all times.

Electrode Pads Shelf Life

Defib pads have a limited guaranteed life span from the date of production due to their chemical composition and therefore come with a best before date.

Pre-connected pads

Having the ability to pre-connect the electrode pads can save time in an emergency.

IP Rating

Standing for Ingress Protection, this relates to the AEDs susceptibility to moisture and dust, so you should consider the type of environment and volume of water and dirt in the surrounding vicinity.

The first digit relates to how the AED is protected from dust and solid objects:

  1. Protection from objects 50mm +
  2. Protection from objects > 12mm
  3. Protection from objects > 2.5mm
  4. Protection from objects > 1mm
  5. Protection from dust
  6. Completely dust tight

The second digit relates to how the AED is protected from moisture:

  1. Protection from vertically falling water drops
  2. Protection from vertically falling water drops and drops up to a 15० angle
  3. Protection from vertically falling water drops and drops up to a 60० angle
  4. Protection from water splashing from all directions
  5. Protection from water jets from all directions
  6. Protection from powerful water jets from all directions
  7. Full submersion up to 1 meter for 30 mins
  8. Any submersion

Semi Automatic Defibrillators vs Fully Automatic Defibrillators

  • A semi-automatic device requires the user to press a button after applying the electro pads, allowing them to check bystanders are standing back before delivering the shock (no one should touching the casualty when a shock is delivered).
  • A fully automatic AED will deliver a shock to the patient without any interaction from the user, which means the defibrillation can begin quickly once the electrode pads have been attached to the casualty. Only one action is required by users so it is therefore simple to use.

Some AEDs such as the ZOLL AED 3™ and ZOLL AED Plus® provide improved support for rescuers in the form of CPR feedback. By monitoring the speed and depth of chest compressions and providing audio or visual instructions, such feedback can guide rescuers to deliver better CPR quality and consequently, according to studies, improve survival rates. The Cardiaid® provides metronomic signals that give a clear rhythm to follow throughout the CPR process.

Best AED for Schools and Educational premises:

green Zoll AED 3For schools including colleges, sixth forms and universities, the ZOLL AED 3™ is the best model as the electrodes can be applied to children or adults as they will automatically adjust. Also, it has visual prompts to ensure that anyone (non English speakers or people that are hard of hearing) can use the device. This defibrillator can be automatic or semi-automatic. The semi-automatic version could be safer to fully ensure no one is touching the casualty when the shock is provided. Alternatively, the Mediana Hearton also offers a switch operated child shock mode.

Best AED for Offices

LifePak CR Plus AEDThe Lifepak CR Plus is ideal for offices as it is designed so that any personnel, trained or untrained can use the device. The fully automatic AED has a straightforward two-step process which includes turning the device on and applying the electrode pads to the casualty. It is also simple and affordable to maintain.

Best AED for Outdoor Work Environments

Red Mediana HeartOn Defibrillator with AED preparation kit and SD cardThis defibrillator automatically turns on when the lid is opened to ensure that defibrillation can start as quickly as possible. The Mediana HeartOn defibrillator comes with a prep kit making it ideal for outdoor use as it has all the supplies with the defibrillator to help with cutting the clothes to ensure the chest is bare for example as these supplies might not be as accessible when working outside.

Defibrillator Storage, Signage & Accessories
