Every once in a while there are cases that use medevac fleets because these case patients have need of a EMT. As these individuals do not have the ability to go on the common air travel charters . That often is when these are individuals that need a breathing machine , jet ambulance companies must be hired. Case patients are dependent on a flight paramedic , and advanced cardiac life support : and therefore they can not be moved by the big commercial airline outfits. In the case that there may be outpatients who are in need of an IV monitor and care for narcotics , or a nurse, there should be crews who are available to help those in need for whatever medical case. Elderly patients frequently look around for medical flight operations with the help of a licensed hospital case worker.
