Subject: Re: gas exchange rates as they effect nitrogen sat


I am learning a lot about cardiovascular physiology from this thread, so 
in that sense I am happy to see it going.  However, I think we're getting 
way into "Wonderland" if we think that we can make any predictions about 
DCI from it.  The basic problem is that we just don't understand as 
much about "fizzyology" as we do about physiology.  The only prediction  
we can make about DCI is that it will be a LONG time before we understand 
it well enough to make any predicitons about DCI.  

I think a more fruitful approach is to go out in the real world and see
what people are actually doing, and what sorts of things get people bent
less often than other sorts of things.  If you look at commercial diving
fishermen in th tropical Pacific, you'll see that they are doing profiles
that will keep you awake at night in a cold sweat.  However, when you
compare their bottom time to decompression time ratio with their rate of
DCI, you'll realize that they know something about decompression that we
"educated" types are missing altogether. The advantage they have is that
they know absolutely nothing about decompression tables (and thus have no
blinders on).  All they know is what has worked and what has not worked in
the course of tens of thousands of dives. 

Aloha,
Rich
