If necessary, they request additional help from police or fire department personnel. They determine the nature and extent of the patient's injuries or illness while also trying to determine whether the patient has epilepsy, diabetes or other preexisting medical conditions. Following strict guidelines, EMT's employ procedures they are certified to use to give appropriate emergency care. When victims are trapped, as in the case of an automobile accident, cave-in or building collapse, EMT's free them or provide emergency care while others free them.
Some conditions are simple enough to be handled following general rules and guidelines.
When transporting patients to a medical facility, EMT's may use special equipment such as backboards, to immobilize them before placing them on stretchers and securing them in the ambulance. While one EMT drives, the other monitors the patient's vital signs and gives additional care as needed. Some EMT's work for hospital trauma centers or jurisdictions which use helicopters to transport critically ill or injured patients. At a medical facility, EMT's transfer patients to the emergency department, report to the staff their observations and the care they provided and help provide emergency treatment. In rural areas, some EMT-Paramedics are trained to treat patients with minor injuries on the scene of an accident or at their home without transporting them to a medical facility.
