The Circuit, the national defibrillator network, provides the NHS ambulance services with vital information about defibrillators across the UK so that in those crucial moments after a cardiac arrest, they can be accessed quickly to help save lives.
Almost all defibs registered on The Circuit can be seen on a map by accessing Defib Finder using a web browser on a computer, tablet or smartphone. This shows the location, accessibility and status of defibs.
