 CFRs are members of the public who have received training to answer ambulance 999 calls, and respond immediately within their local area, during their own time.The schemes originated to provide defibrillation in rural and remote areas, where ambulances could not quickly respond, although they are now present in both rural and urban areas.CFRs are often operated by a local group, in partnership with the regional NHS ambulance trust, and carry a defibrillator and oxygen, along with other equipment as decided by the clinical governance arrangements.
