Is it called an ambulance helicopter or a rescue

Ambulance helicopters. Because rescue helicopters need to store a lot of medical equipment, the need for special modifications to the helicopter, our country is also very lack of professional training institutions for emergency rescue personnel, so our country called ambulance helicopters rather than rescue helicopters. Rescue helicopters are helicopters that are used to search for and rescue parachutists and other people in distress on land and water due to airplane crashes or being hit. They are usually converted from light and medium helicopters. The helicopter is equipped with medical personnel, a certain number of stretchers and medicines, instruments and devices for medical treatment of the sick and wounded on board. Some ambulance helicopters are also equipped with search and rescue devices for search and rescue of people in distress.
