There generally are injured patients that look for help from private air ambulance fleets when these cases do not have the ability to be taken by everyday air travel charters . That usually is because of the fact that they call for special medical attention. As they would be categorized as being in a non-critical situation but the cases in question are having a severe medical situation , med flight crews must be coordinated with. There are individuals who require an IV monitor and care for special medicine , or a paramedic —- and therefore these are the individuals who are unable to go on the usual air travel services. Occasionally there are airevac crews that are there to help families transport loved ones everywhere in the United States. Those people generally search for medivac companies with the assistance of the telephone book.
