A flight nurse is a highly trained registered nurse that normally has experience in not only advanced life support but also critical care. They need the combined skills of an intensive care nurse, emergency nurse and critical care nurse as they deal with a large variety of emergencies and under numerous conditions. There are a large variety of employers that require the expertise of a flight nurse. Some work on medical emergency teams that reach critically injured or ill patients in remote areas and treat them while airlifting the patient to a healthcare facility. Other flight nurses work with teams that land at disaster sites such as car accidents, tornados, earthquakes and fly the seriously injured to hospital trauma centers. They perform the necessary, specialized intensive care while transporting their critically injured or ill patients by plane or helicopter to the appropriate health care facility.
