Subject: Re: Deco theory and breathing rate
"breathing rate" is basicly insignificant, but you could get effects if
you breathed too little relative to normal breahting. The problem is
that you get relaxed and do not produce much CO2, and obviously have
very hig O2, so your reflex drops away. This could make for less gas
exchange, maybe. I ignore it  , and try to breathe about once per minute
to save the gas. There is no reason to do that other than I do not want
to put the correct amount of gas in the water or lug it around, or have
to refill it. I really try to use half of a bottle and save the other
half for the next dive and just leave the regs on the bottles in my van,
and use what's left of my stages for breaks so I do not have to refill
or break down my doubles. I also do not liek to get cold, so breahting
infreqauentlyh saves on heat loss.

 Some of  guys try to breaths as much as they can to get good
ventilation and gas exchnage, and that is probably better.
