Re: Flight Physiology



Well , I've seen all the responses about how to apply your flight physiology lessons to the practice.
The noise produced by the engines have to be blocked because after a while flying it produced with the vibration to fatigue, and, after several years hearing losses.
The altitude physiology have to be watching because after 10,000 ft. the air density ( less oxigen, boyles law) changes, so administer supplementary oxigen (tanks delivered oxigen faster) , endotraqueal , and, foley globes have to be filled with water , no air in cavities because of gases expantion.
Care of vision: used of UV dark glasess while you fly without a patient is recomended to the pilots and crew that likes to fly as co-pilots or in co-pilots place.
Glucose levels check of the patient because one of the effects is hypoglicemia.
Warming of patient , at high altitude lower the temperature is.
Position of the patient also is important because fowlers position don't let all "G" forces apply to the brain ,and if your patient is with epidural hematoma or whatever could gets worst.
Dehydration could be seen in long distances more than and hour flying.
These could be some of the cases where flight physiology may be applied.
Of course that no all the fixed wings are equal, you could have the cabin control in a 421 Cessnas but in case you have to fly without it , you better be careful of all these points.
Anyway if you could read  Richard O. Reinhart, M.D. book of Basic Flight Physiology , it's easy to read and understand.

I have very limited fixed wing experience also, but I can tell you one thing for sure - you want to load your high risk OB patient in with their head to the rear of the aircraft, it's amazing what that G force does to a gravid abdomen!!!

     Hi all - I've got a question for those of you who are very experienced in the realm of fixed wing transport: Exactly how do you apply the principles of flight physiology to your patient assessment and management?
      
       I'm quite familiar with basic flight physiology; the gas laws, the stressors of flight, etc....but what I mean is, how do you use that info?
      
       My experience is almost exclusively with low-altitude helicopter transport - where the effects of changing altitude aren't much of a factor - so I'm just curious to learn what little tricks and assessment techniques you airplane types routinely use during patient preparation and transport. Thanks!
