Ambulance bosses are urging people across Staffordshire to ask for defibrillators to be installed for public use in their communities, so the lives of more cardiac arrest patients can saved.
The small devices, called AEDs, are usually mounted on wall in a yellow box, and are designed to enable members of the public to keep a patient alive until emergency professional arrives.
They work by "shocking" a person's heart into restarting and, if this is done within the first few moments of a cardiac arrest, the patient has a 60 to 70 per cent chance of making a full recovery.
But ambulance bosses are concerned there simply are not enough AEDs installed in public places.
Jamie Richards, of the Staffordshire-based charity AEDDonate, stressed that funds were available for people wanting to get an AED installed.
He said: "If there isn't a defibrillator within 200 metres of where you are now, then please give us a call, because we'd really like to work with you. All we need is people with the links within those areas that can help us hope you get that defibrillator into your community."
