Moshe.., Be honest, deep down do you Know and Understand You Could Die,

Snip... I'm convinced that the strong reaction to
your proposal is directly due to others concern for your continued
existence.

Safety regulations like those for oxygen use are written in the blood of
the dead. This statement is not hyperbole.

Not intending to pile on, but it occurs to me my previous - neutrally-written
- post might be misconstrued as "permission to roll your own with my
blessing." It really wasn't. Rather - since the OP seemed (ahem!) - dead set
on obtaining some specific engineering type information, it was simply an
attempt to point him in a better direction than RAS. My guess is - engineering
information aside - medical equipment manufacturers' reactions will pretty
much mirror RAS'. (Lettuce know!)

It may take some doing in that part of the world (eastern U.S.), but I also
highly recommend jumping through whatever hoops are necessary to "take a
chamber ride" if at all possible, so's to safely get first-hand knowledge of
one's individual oxygen starvation symptoms. In any group of 10 or so
participants, you're likely going to see reactions from "obviously goofy" to
"essentially none before unconsciousness." Regardless of one's reactions,
since it's your life you're betting on, in the absence of first-hand knowledge
only Darwinian-denialists would bet on being in that tiny group capable of
recognizing what's going on in time to actually want/be able to do anything
effective about the situation.

P.S. On my ride, that's what I saw. I also learned I seemed to be lacking in
"obvious symptoms" (beyond likely-terminal-stupidity, of course) for the 5
minutes we spent at 25,000 feet.
