Air ambulance companies organize all details of the flight. The patient only has to be ready to be transported. The company will also coordinate with doctors in the hospital of destination, so that everything is ready to welcome the patient the very first moment he steps inside. Most medical air transport companies have business jets which make the flight extremely safe and as comfortable as can be for the patient and for the family members that travel with him. Such jets are designed for long distance transports, so they don't need frequent fuel stops, even in case of longer distances.
