Just a quicky reply as I do not have time to read the whole thread...I beg forgiveness therefore if this has already been mentioned...but as for 'medical extended experience' think atmospheric pressure changes to the body due altitude changes during flight.
This, I understand, is a significant factor when considering all things anaesthesia and when dealing with internal bleeding, especially with head trauma.
A good sideline of enquiry, I suggest, is the care of 'patient accompanying' passengers:, ie: child patient accompanied by terrified but otherwise uninjured mother. Both need careful handling, but the latter is not sedated, is maybe in shock, is half scared out of her mind, has never been in a helicopter before, etc, etc. Now there's a challenge for the airborne EMS professional, especially when their hands are already full.
