There are 2 issues here:
1. Payment (recompense) for effectively being on duty
2. Authority for the Dr/Nurse to treat based on the legal jurisdiction & position of the aircraft.
I admire Dr’s & Nurses for putting their hands up to offer help, but unless they are protected i.e. the airline confirm they are authorizing them to treat the patient, I think they must be crazy to help.
There is a recent case of a Dr who was arrested in UAE whilst in transit and charged with manslaughter….
OK – he was not treating a patient in an aeroplane, but this does highlight the perils…
The airlines should SUPPORT a volunteer medic, working on one of their airlines BEFORE the medic agrees to treat.
