Subject: Re: Going Up
Joel,

We are both from NYC but what is up with this attitude? Tech diving
approaches
change, and maybe change scares some people, but I'll put up with it to
make my
point. Interestingly, your chest pounding "I can omit deco, save a life,
and then
do a special schedule and collect scotch" sounds like 'I'm good to 240
on air'.
First I will make my point, second I will clarify the scenario and then
I will
continue the 'game'.

I was tought and believe no one survives a blow up.

In your scenario, BOTH you and the unconsceous diver have times of 30
min at
225fsw (57-58 msw)

Which signs are they? There are only two signs underwater - breathing
and
activity.

Case A. If I'm not breathing when you find me I've seen my last sunset.
Don't
anyone fool themselves that is not the case. The 5-6 min "cruise" to the
suface
you are going to continue will by itself ensure permanent brain damage,
that is if
I survive the bend. But that is not the scenario.

Case B. Maybe I'm siezing - ox tox. Moving me up right away will give me
that
pnuemothorax and AGE you point out, since you do not breathe while
you're having a
siezure.. But don't wait, just add those problems to the little pile
I've already
got. This is the case where I may come out of it in a short time,
perhaps a little
shallower.

Case C. Lets just say I'm out of it, but breathing. Ok I'm all yours.
(BTW, 5-6
min to get me nuetrally bouyant if I'm not, cruise to the anchor line,
find/clip
on stages and ascend controlled 225 fsw to the surface keeping both our
bouyancy's
right and switch gas? Come on. The right ascent speed alone would take
7.5 min)
Let's fix the fairytale, er - scenario, here. 10 -12 minutes to the
surface with
multiple ascent speed violations, maybe some descent time in there too.

Since Murphy has left for the Caymans obviously the boat crew sees you
as you
break the surface. That 10 seconds of screaming important information to
the crew
is understood the fist time and there is a big ok signal given to you
and back
down you go. There is actually no important info given. What is the
difference in
the boat crew's response to a diver out of it on the surface who was
unconscious
on the bottom and one that blacked out as he surfaced after doing all
his deco
because he just remembered it is his wife's birthday today and he forgot
just like
last year. They are going to get him out of the water and assess and
treat him,
which made yelling 'get him out' the most important thing you said.

Why do you need company on your omitted deco hang? This is an invitation
for a
charlie foxtrot if there ever was one. Probably the gas you need the
most right
away is the one you have the least of. Is that why you yelled to the
boat what gas
you were on? (Maybe there is some of it laying around in a handy stage
bottle like
the rip open placards you mention. If this is truley part of your dive
disaster
planning then I commend you on thinking this all the way through!) More
than
likely, if you have any bottom gas left at all, and the boat understood
to bring
you bottom gas from your instructions, a diver will arrive a bit later
than you
want with someone else's bottom mix on their back that they too will
have to use
and share with you a la long hose. So now there you on an extended hang,
with
another diver sent to you breathing mix that needs to do deco too,
albeit not as
much as you. (Don't forget too, he may have just cleared his dive a half
an hour
ago.) But how did he know what table to bring for himself? Maybe he is
on an air
stage, and can just follow a computer up or share some of your deco gas.
No,
hopefully he brought extra deco gas for you. And this was all done quick
becuase
you needed the bottom mix ASAP. Don't forget about peaceful ol me on
deck. How do
you spell cluster? There is so much going on here you will need the
entire cast of
ER to sort this shit out. The situation as it is, and the obvious
priorities
recognized, I'm dead.

You bet you will, and the diver who helped you, if there is room for you
both.
After all, I was taken by helo to a chamber long before you were even
up.

Lets go back and return to finding other divers on the line doing deco
and you
pass me off to them. How is the important information going to get
screamed to the
boat crew? Is some other diver just happening to move up a stop to
another who
moves up a stop and I get passed all the way to the surface. The timing
is magic.
What is this daisy chain? You mean I get let up controlled by a string
to the
surface from the last diver at 20 fsw/9msw? This will take forever, I
will
probably get dropped, or float away, or hit my head on the boat and then
you will
get upset. Worse is if someone else while playing pass the dead diver
really
messes up thier deco and is hurt. This is probably a better charlie
foxtrot than
the first.

Thanks Joel. But if its me that you do come across, use this algorythm
to make
your decision.

Case A. Not Breathing Shake me and see if I breathe. If not, tye me to
the wreck,
reel off to the anchor, come back for me next dive. Do not try moving me
or
anything else un-routine at this point in your dive. I'm dead.

Case B & C. Siezing, breathing, out of it. Ascend doing your stops
untill I come
out of it. If I do not come out of it and I am breathing with the reg in
my gob
just do the deco as you would normally. THIS IS THE BEST THING FOR ME.
Maybe I
will come out of it with a little more time. Once I loose the reg and
drowning is
eminant, shoot me to the surface by jamming down on my wing inflator.
Carry on the
deco. I am now no worse off than I will ever be otherwise. What deco I
was able to
do might mean the difference.

Right Joel. I will drop my cameras at the earliest indication that
someone needs
help. I will not babysit a dead body to the surface. I know the
difference.
