The patients that are noncitizens or must be transported are flown by air evacuation operations. As they must be transferred and/or are in the US and internationally , jet ambulance fleets have to be used. Individuals call for a EMT and IV solutions and infusion sets while they travel. When injured patients are unable to be sent by everyday air travel charters — because these individuals call for a flight nurse , and/or a complete ICU/CCU setup, there almost always are services that are available to help those in need . Emergency air evacuation businesses generally can be contacted by the spouse of the patient with the assistance of the many medical directories available online.
