The charity Air Ambulance Northern Ireland, in partnership with the Northern Ireland Ambulance Service, provides the Helicopter Emergency Medical Service for Northern Ireland. The service brings urgent medical assistance to anywhere in the province, operating seven days a week for 12 hours per day. It can get to anywhere in Northern Ireland in approximately twenty-five minutes. The HEMS team attend patients who are seriously ill or injured, bringing emergency pre-hospital care direct to the casualty with the aim of saving lives, brains and limbs. Air Ambulance NI needs to raise £2million each year to maintain this service so public donations are crucial.
