A few weeks back, LH flight from FRA-HKG, a lady in Y fainted. Calls for medical assistance resulted in a slightly tipsy young-ish doctor rocking up to the galley (me ), as well as several other practitioners of medicine of the Chinese tradition! Whilst I took the blood pressure and re-assured everybody this she'll be fine with some fluids and putting her feet up, the Chinese docs proceeded to accu-pressure her and rub her in various places until the colour came back to her face - me and a FA observed with fascination

It's an interesting topic though - given these situations, I would much rather a paramedic come to my assistance than... a "slightly tipsy young-ish doctor". My colleagues and I have had discussions about whether we'd ever owe up to the fact that we were docs whilst travelling; since at least from my uni, we're not bound by the Hippocratic oath (and we're young, relatively inexperienced etc. etc.) I think ultimately, instinct and potential guilt wins out.
