Subject: RE: WHY WE DO NOT USE 80/20
To: techdiver@aquanaut.com

   Jon, you are exactly right about commercial divers not useing
oxygen, They use 80/20 at 10 feet and they use air up to that point.
Air is more natural , since that is what we breath, so it is better to
decopmpress on . Studies have shown that air is better than
decompressing on pure O2 for thuis reason. Since this is a much mroe
efficient offgassing than oxygen, most commercial divers use it for
eveything. Since it is more efficient, you can use it like oxygen and
jsut set your deco program for oxygen, but really use air. 

   Before they hospitalized me, I was jsut starting to show how aliens
were able to land on our planet, decompress with 80/20, and be ablke
to strep right out of their spaceships in minutes, rahter than HOURS
with pure oxygen, and they showed no ill effects from this at all. In
fact, in most aliens the vaoconstricitve effect in far mor pronounced,
and that is why in earlier alien drwawings from the fist sightings,
the eyes were bugged out from deompression sickeness, much like a
Groupper brought up from the dpeths by a fisherman. 

   I hear somebadyhd coming, so byue for now.
