A new defibrillator has been installed outside Hunsdon Village Hall for use in emergencies.
You can read all about how to use a defib machine to save a life here on the Hunsdon Village website.
Every second counts when someone suffers a cardiac arrest. Always call an ambulance, but time is absolutely critical when someone has suffered a heart attack.
Watch the video below to find out how to use the defib.
If you were trained and knew how to access the defib, then you could save the life of a relation, friend or other loved one.
The defibrillator is installed with its own instructions to help you in an emergency, so you should never be afraid of using one.
