Parts of Hertfordshire are so rural - the Ambulance service struggles to make it there within the target time of 8 minutes.
The East of England Ambulance Service are recruiting more Community Responders who can get to the scene quickly and provide care.
This would be most helpful in a cardiac arrest situation.
Simon Marshall is the Community Partnership Training Officer for the service, he says: "If somebody turns up and they're doing CPR and they've got a defibrillator and they've shocked the person, they've got a 30% chance of surviving."
The responders would be sent as a first response to an ambulance call out in a rural area and then backed up by an ambulance crew or paramedic.
