Subject: Re: A broken clock is right twice a day
Good choices, only you will now have to tell me who is crowing about
this. We have been over Armentrout's incident repeatedly, I explained
it, Jess explained it. The lesson for us to learn here is that Jess
should have had his parents go to Genentech and do a litle modification
of his genes.He and I did the same dive, he got hit. I blew most of the
deco off and had no problem.

What he did different than I was to not rest quietly before breaking
down his gear an beginning the hike to camp. This period following
surfacing is when a shower of bubbles is released, and if any get by due
to PFO or other shunt, or get through the lung capillary beds due to
overload, you will take a cns hit. I prefer getting tested, Trout got
his test this way. He quit doing this kind of dive - lesson learned. He
also got "skin bent" - lesson learned there by him was to drop off any
excess fat since it likes to get bent on anyone. He did that already, so
his regular diving is fine.

Our profile by the way was 350 when our depth guages locked out , not
exactly an easy one to decompress from. In fact, I found it so hard that
I did not even bother.

TC broke one of our rules set by Parker Turner back in 1990, which is no
bounce diving after a dive. Our experience has been that support divers
get CNS hits retreiving shallow bottles on a straight no stop bounce if
they have just done a dive themselves, so we make divers sit out until
clear before doing any bounce support work. We also do not allow free
diving after a dive for the same reasons. TC retrieved his own bottles
after surfacing and got hit. The chances of him every doing that again
are slim. The warning he provided for the rest of us will keep anyone
from doing it any time soon.

I discuss this kind of thing on our own list, Freeattic, and it was well
gone over . The machinism is that the bubbles released by the last
pressure drop when surfacing are then compressed on the bounce long
enough to get past the capillary beds of the lungs which act like
filters for bubbbles, and then re-expand down stream on the arterial
side where they wreak havoc . They usually hit the brain and spine
first.

If dive instruction had the kind of information we have, things would be
a lot different, would they not? By the way, Tod, that day marked
something in the order of 15,000 man hours of extreme diving by WKPP
divers, and all you guys have to come after us on is a bottle retrieval
and somebody kamakaze diving with me in the jungle on a non WKPP dive.
Not good enough.

Our record is the best in the business, including commerical diving in
the oil fields and the European commercial diving Union.

I will continue to hammer the strokes with extereme prejudice.

I will also go ahead and admit one of the dumbest things I ever did: I
strapped a nitrox pony between my doubles and did a dive in  the engine
room of a wreck down here about 10 years ago. I got into the engine room
, but could not get out. I had to drop down under then engines and go
out through a hole in one of the cargo bays.  The girl who was with me
also had the pony thing, but she could fit out around the engine. Her
boyfriend took a picture of this strokery, and Tom Mouth proudly
displays this picture blown up like a poster on the wall of his
classroom at IANTD headquarters. Tod, are you begining to see what is
wrong here , or no?

I do something really stupid, and it is in the IANTD classroom on the
wall. I am suprised that Christina Young does not have this on her web
page of horrors. I do something smart, and Mouth fights it to the end.
We figure things out and change, the idots keep doing them over and over
and over. Tod? Do you see this or not?

Come up with something better than dcs. I sprained my anke 13 times
playing football. I did not learn anything other than "don't play". This
is how I view DCS. I still wore low shoes and no tape, and I still deco
on the short version. Both are faster.
