Cardiac Coverage Report

Welcome to our first Cardiac Coverage report which pulls together data from UK Ambulance Services to understand the coverage of registered defibrillators across the UK by the Local Authority. 

We know from this data that there are 27,150 registered units, but it is estimated that a further 70,000 units remain unregistered, and this could be the difference between life and death.

Is your unit registered?  Registration allows the emergency services to direct callers to their nearest available unit, saving precious time.  Please visit

The average number of registered defibrillators per 10,000 people is 4.91 in Great Britain. Where does your council stand?

What is Sudden Cardiac Arrest?

Sudden Cardiac Arrest (SCA) is the abrupt loss of heart function, breathing and consciousness. The condition usually results from a problem with your heart's electrical system, which disrupts your heart's pumping action and stops blood flow to your body. This results in the individual collapsing, being unresponsive, and not breathing. There are over 60,000 Out-of-Hospital Cardiac Arrests (OHCA) in the UK each year, with around 30,000 resuscitations attempted from an ambulance service. 

Survival is possible with fast, appropriate care. Cardiopulmonary resuscitation (CPR) and using a defibrillator (AED) help improve the chances of survival until emergency services arrive but must be administered within 3-5 minutes of collapse.  For every minute that treatment is delayed, survival chances decrease by 10%.  Prompt action is vital.
