Re: Deputies try to raise doomed sub

["Alan D. Secor" <secor@btv.ibm.com>]

With all this talk about air embolisms and the bends, I think you guys
are forgetting one simple fact....this guy was in a 1 atm sub and
therefore the air in his lungs was at 1 atm, same as if he were doing
a breath hold surface dive.  An air embolism requires an over-expansion
injury to the lungs, which requires breathing *compressed* air, holding
one's breath, and doing an ascent.  The only pressure related injury
he should have suffered would have been blown ear drums as Jon stated
below.
