When you’re ready to get a defibrillator, you’ll need to choose which one to get.  Each type offers unique benefits and considerations that can impact their effectiveness in saving lives during a cardiac emergency. 

The type of defibrillator you choose will depend on:


Automatic vs Semi-automatic defibrillators

Defibrillators are either semi-automatic or fully automatic.  The difference is how much action is needed from the person using it.


Benefits of Semi-automatic v Automatic defibrillators

Semi-automatic defibrillators: 


Fully automatic Defibrillators  


Common Features of Both Types: 


Will it work for children?

For children under 8, the shock from a defibrillator needs to be weaker than it is for adults.  Some defibrillators let you switch easily from adult to child mode.  Others need different electrode pads that are suitable for use on children or a special ‘child key’ to switch mode.

We always recommend a defibrillator with a built-in-switch as this can save vital time during an emergency.

If you’re not sure whether to get a semi-automatic or fully automatic defibrillator, we can talk through your needs.

London Hearts realises that it is not always possible to locate a Defibrillator externally due to logistics and specific requirements.
We are therefore currently running this special Defibrillator scheme to assist businesses, sports clubs, individuals etc. to obtain an internal / portable dual functioning defibrillator for just c£660.
The aim of this scheme is to generally increase the numbers of life-saving defibrillators in order to improve survival rates from out of hospital cardiac arrests.

There are over 50,000 out of hospital cardiac arrests each year in the UK, but less than one in ten people will survive. Every minute without CPR and defibrillation after a cardiac arrest can reduce the chance of survival by up to 10 per cent. Quick CPR and defibrillation are the only chance of saving someone’s life. If a Defibrillator is applied to the patient within the first 3-5 mins, then the chances of survival increase from 6% to over 70%.
The London Hearts Trustee states, “Every defibrillator has the power to save a person’s life, as a charity we are thrilled to assist as many people as possible throughout the UK to obtain a Defibrillator. There are simply not enough defibrillators. Everyone should have access to these life saving devices. Our mission is to make sure everyone is never more than 200 meters from one at any time.”

To be eligible for this scheme you simply must be:

• Within the UK

• Be committed to promoting London Hearts free online CPR/Defibrillator training with the resources provided.

• We also request you provide us with a photograph of the Defibrillator with person/-s present which we can then include on our social media ‘Every Second Counts’ to help continue raising awareness.

• Responsible for ongoing maintenance

The Scheme is being run on a first come first served basis until all units have been claimed.
