DCS incident analysis requested

OK, go run a 6K race, then do a 125 ft dive, then a 130ft dive, then a 132 ft dive and tell us how you feel. Oh, do a 2 1/2 hour SI between dives. Oh, yeah, tells us what your puter says.

Be sure to do some aerobics after the dive too.

Actually, don't do that, it's too risky.

Wooooooosh

 

[JeffG]

How does this affect the DIVE PROFILE? How does this affect decompression and DCS?

There seems to be a consensus that he got bent because of a bad profile, or too short of SI or 3 dives in one day or some other sort of thing.

Do you have a specific problem with the PROFILE reported .... such as Dive 1 was too long for the average depth?

If you do have a specific problem, please explain.

Mr Fisherman...toss another lure in

Never dive without it

I recommend that you never do.

Any dive where you have a deco obligation, 0 deco training, and are doing the deco according to what a computer specifically not designed for decompression diving is telling you to do, then yes.

That is risky.

Yes, and add his level of strenuous exercise before the dives and that makes it more risky.

Hold that woooooooooosh for a while.

I recommend that you never do.

" One way of adjusting to the fitness needs of diving is to carefully plan your dives, avoiding situations requiring excess physical exertion above and beyond your physical capacities. This works well for the elderly diver or the diver who has physical incapacities. The best way is to exercise regularly.

For diving fitness, a moderate exercise program that can be done 4-5 days a week is adequate for the casual diver. "


The key is to keep any pre-dive exercise to the moderate level.

Got any proof of that?

Didn't think so.

Exercise Causes an immediate response

"Exercise generally causes an immediate response in the cardiovascular system. This response includes local blood flow changes which then cause reflexes that then cause an increased cardiac output (how much blood the heart is pumping out). From the cardiovascular standpoint, exercise is any activity that raises the resting oxygen consumption above basal levels. Thus swimming, walking with heavy gear, climbing ladders and performing heavy labor relating to diving are all sensed by the heart and cardiovascular system as forms of exercise and require an increased output. " Medicine online, approved by DAN

Exercise, in moderation, should be no problem, in the fit diver, but avoid EXCESSIVE forms of physical activity just prior to diving, especially deep diving, and repetitive diving.

Hope this helps.
