We are called if a patient needs our clinical skills in critical care and/or the additional drugs and specialist medical equipment we carry.
We are dispatched by the HEMS (Helicopter Emergency Medical Service) desk in Exeter, which is run by the South Western Ambulance Service NHS Foundation Trust (SWASfT).
The dispatchers monitor all calls to the ambulance service in the area and identify incidents where an air ambulance is needed.
The dispatchers listen into calls, phone back callers and get updates from ambulance crews on scene.
In addition, we can be called upon for support by land ambulances and other air ambulance crews, or liaise directly with the HEMS desk for incidents we locate.
