The Joe Humphries Memorial Trust describe a defibrillator as: "a computerised medical device which delivers an electrical current through the chest, which aims to shock the heart back into a normal rhythm allowing it to pump again.
"Defibrillators can automatically detect the heart's rhythm, without intervention by an operator, whether it’s a case cardiac arrest and whether defibrillation (an electrical shock to the heart) should be performed.
"The speedy use of this automated technology can significantly improve the quality of life of a survivor, as the longer the brain is starved of oxygen, the more the damage that can occur."
Andrew explained that there’s typically two options when it comes to accessing or providing a defibrillator:
- An automated external defibrillator (AED) – a lightweight, portable device that can be taken to multiple locations or spaces. This is particularly useful for organisations that hire or use different facilities; or
- A community public access defibrillator (cPAD) – a device stored in a cabinet that’s typically accessible to members of the public. Some cPADs are available 24 hours a day, although others have restricted access hours. cPADs are often fixed to the outside of community buildings or in buildings that are permanently open, like hotels. To unlock cPADs in external cabinets, users need to call 999 for the code; for those inside buildings, a code can be accessed from those responsible for running the building.
Locating or registering a defibrillator
Active Charnwood encourage registering all defibrillators and any access restrictions on The Circuit, which is supported by the British Heart Foundation.
This makes it easy for people to find their closest available defibrillator in an emergency and access the appropriate code to unlock them.
