Life-saving equipment is being unveiled at a Medway football ground this week, as an appeal hopes to identify other defibrillators across the south east.

Chatham Town FC will unveil its new public defibrillator on Friday, after a campaign by MP Tracey Crouch.

The easy-to-use device delivers an electric shock to the heart of someone who is in cardiac arrest.

The equipment has been installed outside Chats’ ground in Maidstone Road so the whole community can use it.

The unveiling comes as South East Coast Ambulance Service (Secamb) launches its Shoctober campaign to locate machines that have been bought with good intentions but are not registered.

It is essential for the ambulance service to know the whereabouts of all public defibrillators so they can direct 999 callers to them in the event of a cardiac arrest.

SECAmb is asking people to #FindTheDefib, take a selfie next to one and tweet the picture to @SECAmbulance and @SECAmbulanceCFR.

SECAmb’s Malcolm Legg said: “It’s a fun way to raise awareness of an important issue. Whenever you see a defibrillator grab your phone and take a selfie, even if you think it’s one we already know about.

"Send us as much information you can about the location and we can check it against our database.”

Chatham MP Miss Crouch has called for more defibrillators across her constituency and the equipment being installed at Chatham Town has been funded by her assistant Georgina Nicolettos, who ran the London Marathon in 2014 to support the campaign.

It was originally due to be unveiled on September 30 but this will now take place on Friday at 2pm.

The use of CPR and a defibrillator within three minutes of a heart attack improves chances of survival from 5% to 75%.

A portable device helped save the life of Premier League footballer Fabrice Muamba and he has campaigned for more of them in public places.

They can be used safely by people who have had no training, with easy-to-follow, step-by-step instructions.
