Breathing rate, air integrated computers and DCI correlation

[boulderjohn]

I find it interesting that one of the foremost authorities on decompression on the planet joins the forum with an authoritative post and almost no one seems to pay any attention.

Ahhhh. . . but that presumes BD's opinions are based in fact. Religion is the suspension of disbelief (IMHO of course)

I don’t understand how you can answer questions with such authority, and certainty.

Due to the fact that I am the "Head Beaver Diver"!

For me the question has been answered and this topic has been resolved.

Dr. Deco's expert explanation makes full sense and avoids any speculation or opinions.

Unless somebody can post something solid like he did to the contrary then im good

I was talking about Dr. Deco--Michael Powell. There are few people who can match his credentials in terms of decompression theory.

Have you ever downloaded your dive computer and analyzed your dives?

Have you ever used an air integrated dive computer?

I just analyzed Saturday's dive. 165fsw for :31 minutes on Tx23/30, followed by decompression on 50% and 80%. We planned the dives using 30/85 GF, and we ran a backup 99/99 model, in the event of an underwater injury. We displaced that that crazy gas you're so concerned about, Nitrogen, with 30% helium to reduce our END. We all know our SAC rates for working and deco and we knew exactly how much gas we'd need. For the record, we hit those numbers within 100psi even accounting for two minor entanglements.

Here's a question...? Why don't you *PLAN* a dive to *BE* conservative versus nearly *KILLING* someone before figuring out very simple dives. If you actually had a clue about the model, you could simply make the necessary changes and develop a plan to account for the variable you're trying to cover. Doing it within the dive means you're a battery failure, or an o-ring failure away from clueless.

OH! :hurt:I thought you were talking about me.

Please post your profile.

Redudancy! Dive with two or more dive computers. Simple.

Please post your profile.

Why would I post the profiles? You post your bent diver profiles first including accurate dates and times.

By the way, I dive with two Shearwater Petrels, and I have the profiles if that's some sort of "challenge".

Getting too macho around here. I bow to the tec diver. The rest of us are unworthy.

I have indicated that her SAC of .4 cuft/min is normal or on the low side.In my experience, .3 cuft/min is average for an experienced female diver.Yes, for males, I have found .4 cuft/min to be on the low side, but not extreme. Our new divers have an average SAC of 1.0 cuft/min. As they progress from the pool through their Open Water dives, their SAC improves. After a week long trip of diving & downloading their dives, the ave. SAC for our male divers is .6 cuft/min & for our female divers is .4 cuft/min.Perhaps, using this "new" tool enables divers to obtain a better SAC?

Since the late 90's ( around 15 years ), I have found downloading AI computers turns out better divers with a lower risk of DCS.

What makes you believe this???? Can you provide any quantification to "lower"?
