There is a defibrillator in the centre of the village, attached to the Fox Public House.
If an emergency arises and you need to use the device, phone the Ambulance Service via 999 and they will give you the access code to open the case to the defibrillator. The machine itself will give spoken instructions and lead you through the process of applying the device to the patient and applying CPR if necessary.
If you wish to familiarize yourself with the operation of the defibrillator the model installed is the Powerheart G5 Semi Automatic with CPR Feedback
Below is a video and a link to a PDF brochure from the manufacturer showing the use of the machine.
