Yes, however, I bet that the O2 kit is not usable underwater!!!  These
kits (that I've seen - as we were taught to use in our EMT course)
come with masks that fit over the nose and mouth and are either
constant flow (with or without reservoir and in several different
flavors) or demand valve (still fitting over the mouth and nose).
Given their construction, I doubt that they would work very well
underwater - (or am I all wet here ???  :^) Now, if the O2 carried on
the dive boat is an O2 tank with a SCUBA regulator, that's a different
story (at least about the *viability* of using it underwater), but I
bet that's not what these boats have.

I doubt that the person in charge of the (commercial dive) operation
would want to send a potentially injured person back in the water.  Of
course, for the very high tech/supported diver this may be a different
story, but I don't think that's what Tom was talking about.

Changing the topic (very) slightly, I remember a conversation on this
group from several months ago that said that some new evidence would
be brought forth (perhaps early in '95) that showed that if DCI
symptoms (perhaps only severe DCI ???) aren't treated very quickly (I
believe the time period mentioned was ***7 minutes*** - yes seven)
that permanent defects could occur.  I have this mail saved at home
and I guess I could always look it up on aquanaut, but to the person
who posted it (I remember that it was someone here that is well
respected) - what is happening with this information???  Is it still
going to be reported or has it been refuted???
