A fire engine responds with the rescue on all Emergency Medical Services (EMS) calls that are of an unknown nature or may require advanced life support or additional manpower. The firefighters assigned to the fire engine are trained to the same Cardiac EMT level as the members assigned to the rescue. Therefore, the engine crew can assist the members of rescue by obtaining EKG's, starting IV's, securing patient airways, performing CPR, and administering medications. In extreme medical emergencies an engine company member will serve as a driver for the rescue. This allows both EMT's assigned to the rescue the ability to care for the patient while enroute to the hospital.
