At any rate, the best thing to do is,to get all the medical skill on the aircraft together and work as a team
This would be my first concern during any airborne emergency. Being one of the slightly staler varieties of medics, I'm sure an EMT or an A&E nurse would be a lot more current and slick with the ALS algorithms. However, I am convinced the knowledge I and any other fully qualified medical practitioner have, would come in useful, especially with regards to considering differential diagnoses and further treatment.
Flapassym, if the powers that be have their say, it won't be long until your surgery might be done by someone not medically qualified... In some places and depending on what procedure is being done, this is already happening...
Apparently my colleagues and I are far too expensive to be employed to do what we are actually trained to do...
