Tibshelf and District Community First Response (CFR) scheme have been given an ambulance-style vehicle by East Midlands Ambulance service (EMAS) that has helped 20 people in its first two weeks.
Volunteers for the CFR attend serious 999 calls, meaning patients can be treated while paramedics travel to the scene.
They are trained in defibrillation and help patients who are suffering with strokes, breathing problems, chest pains, and other problems.
The new Skoda Fabia has been fitted with communication equipment meaning they can respond quicker.
CFR schemes are run by volunteers who rely on funding from local businesses and the public.
