most of the emt's i know are young--mid 20's
most of the flight nurses i know are a bit older---mid 30's/40's
the military is the only place i know with an age limit for nurses
i am in my 40's, and still planning to be a flight nurse--just gotta lose this extra 50 #s(huff, puff)---there is a weight limit with our flight team...
in my research on other requirements, i have found flight teams like a nurse with adult and peds experience, national certification, some require rn's to have emt certification.
hope this helps
