I heard yet another story. Peter guy hit on one of the points. I mean, I am only a layman, but I too wouldn't provide oxygen based on the cousin's (own statement) words "she has diabetes, she needs oxygen".
Here is the story that I got. The flight attendent responded that "we don't provide O2 for that" (diabetes), but said she would go ask the pilot.
-- Following from a statement from another passenger--(don't know what answer the FA got), When the FA returned the lady was now having trouble breathing and they got O2 for her. -
Fact based on several statments-Only the cousin and a couple of passengers, not the doctor or nurses have made a statement that there was no O2 in the bottles. --Here, let me hold a bottle up and you tell me if it has O2 in it and how full it is. Unless you are using it you don't know. On a plane, forget about hearing the hiss (unless it is full up) over the engines and commotion.
Fact - only a statement from the cousin stated the AED didn't work. The nurses, Doctors and FA didn't make any statements as such (at least as of the last time I read any story on this.).
Fact - AEDs don't always shock (which could be construed as not working to bystander). AEDs must find certain conditions. AEDs you will find on planes, in gyms, and other like places don't have manual shock functions because the people using them are not trained to do that and would probably end up killing people by shocking them any time the machine decided not to. AEDs (might be called something else) in hospitals have that option because, guess what, doctors have the training to override the machine.
--from the American Red Cross--
"If a "shockable" rhythm is detected, the machine will charge itself and instruct the rescuer to stand clear of the victim and to press the shock button."
--from
Youth Sports - Sports Moms on the operation of a common AED model--
"If the victim is not in cardiac arrest, or has a rhythm that is untreatable with difibrillation, the Defibtech AED will make that determination and not allow a user to adminster a shock.
Sooo, as for AEDs, not shocking is not a sign of not working. So far nobody that was qualified to decide such has made a statement that the AED was faulty. (as of the last I have heard on this story.).
Fact is. Nobody has first hand knowledge here. Until the proper authorities complete their investigation then we will not know exactly what happened, maybe.
