Apparently, the lesson is that if you can't be successful, you shouldn't try.
Ryanair spokesperson: "As the cause of death of this passenger has yet to be confirmed, it is pointless to speculate whether any piece of medical equipment could or would have averted this tragedy. All of our thoughts and prayers remain with the friends and family of the deceased."
norunway: Not to stray from the point the young woman who died on this flight could not have been saved even if she had of been traveling on a CAA registered airplane so why don't you have a think about that
I doubt very much anybody knew that the chances of success were slim when they began CPR (I've always been trained to try regardless), but it seems here that people are using the clarity of hind sight to justify the lack of medical equipment and an ill-prepared crew. Heaven forbid if they even consider an AED on board.
