The Nepal Ambulance Service (NAS) is a non-profit initiative dedicated to the establishment of an emergency medical response system (EMS) in the greater Kathmandu and Patan Municipalities, later to be expanded nationwide.

This system will provide rapid ambulance transport to hospitals along with life-saving medical care by trained emergency medical technicians (EMTs) for sick and injured people regardless of their ability to pay.

NAS aims to operate fully equipped and staffed ambulances via a central dispatch facility with radio communication between area hospitals and ambulances in order to ensure rapid transport and treatment for individual patients. Nas EMTs will be trained by Stanford University School of Medicine (USA) Experts from Standford Emergency Medicine International (SEMI).
