Sure, if you are in that situation you try and relax and reduce your breathing rate, but if he also meant to try and deliberately not breathe as much, what is the benefit? By reducing his breathing he reduces the opportunity to eliminate nitrogen and loads up on CO2. What is this? When you are out of gas your deco is over. Simple huh?! Feel free to load up on CO2... that ought to be interesting... Modify your breathing indeed.... sounds like some kind of Tai Chi BS. Jeff Greg Kuiper wrote: Jeff Bentley, Of course I meant the comment "to modify your breathing if you are short on deco gas". If an emergency situation comes up that causes me to extend my decompression and I don't have enough deco gas or back gas then I am going to slow down my breathing to extend my deco. as long as possible before surfacing. Example: 360' trimix dive, Buddy gets entagled in wreck and has back gas failure due to a number of reasons. He shares long hose with me and it takes an additional twenty minutes to get him free and to the first deco stop. We both now have an awful lot of deco ahead and not enough gas at our current breathing rate. Do you think it would it would be better to continue breathing at a normal pace and blow your decompression or slow down your breathing, relax and get as much deco as possible? It is easy to cut your breathing in half at deco if you think about it.
