I Use no air?

[Kilili]

Zombie divers are like that... They don't breathe.

Do you want to switch kid? God Bless you.

I have a student of mine who is small and uses no air just like you. It drives boat DM and captains crazy.

The air you use depends on 2 factors. Lung tidal volume and breathing rate. Cardiovascular fitness, relaxation and proper breathing patterns control the rate at which you breath. Your lung tidal volume is dictated by your physical make-up.

Congrats.... you have small lungs...and a good breathing rate.

Some people just have freakishly small consumption rates. Brett Gilliam (who is a biggish guy) used to use very little gas on his dives.

The title of the OP's post does remind me of an amusing story about a British technical diver who was diving one of the ludicrously deep wreck dives in British waters (about 450 fsw) on open circuit. After a few minutes he checks his gas only to discover he still has a completely full set of doubles. Turned out he had a cheap SPG, and the sheer water pressure had pressed the glass so hard against the needle that it was stuck!

I guess as long as you don't come BACK with more air than you started with life is good!


(hmmmm...Twilight Zone episode?)

It happens like that for some of us. Me and my dad were drift diving in a river the other day. He came up with 700 PSI and I came up with 2200 PSI. Now, he tends to leave his regulator in at the surface more than I do, but when we picked the tanks I gave him one with 300 PSI more than mine.

As mentioned above, physical fitness, in addition to peace of mind and general style of diving have a lot to do with how much air you use. Enjoy your God given gift!:cool3:

that will happen with plastic gauges. something to look out for

I'm super jealous. I'm a medium-sized guy in fairly good health and my RMV is around 0.8 cuft/min.atm. Video surveillance shows that I'm generally high-strung and pretty stiff all the time, in or out of the water. Enjoy your gas!

As long as you aren't getting headaches or feeling nauseated after your dives, just consider yourself lucky! There ARE data showing that some people become rather CO2 tolerant when on scuba. Since CO2 is the major drive for respiration, CO2 tolerance results in lower RMVs -- but this can be a significant problem on deep dives, as CO2 and nitrogen are additive in their narcotic effects. As I recall, a death on the Doria recounted in one of my books occurred in a diver who was known for skip-breathing to extend his bottom time. He was found with empty tanks and no sign of struggle at all, and it was hypothesized that he was simply incapacitated by narcosis.

But some of us just fall into a very efficent breathing pattern fairly naturally. Although I am small, which is an advantage, I have always had a low gas consumption rate. It was the only thing in scuba that I did right from the beginning! (Irritates the stink out of your buddies, doesn't it?)

my sac rate is turrible.
