Does smoking lower your SCR?

[TheRedHead]

Anyway, this is what I was meant by semi-orthogonal

Dang. No differential equation...I feel cheated.

If you measure the maximum amount of air you can move in and out of your lungs in one minute, that number will usually be lower for a given age and size of person in a smoker, as compared with a nonsmoker.

Isn't that the answer right there then? If a non-smoker 'moves' more air than a smoker per minute then his/her SAC rate would be higher. Presumably this becomes more true in an individual person. A smoker can move 'x' units/minute, when they become a non-smoker that volume increases to 'x+y'/minute. They can simply move more air, and do, so a tank goes quicker.

You guys do the same and see how long you can do it?

Twenty years ago I was a light (one to two packs a week) smoker.

Breath hold with no prep, one exhale/Inhale and hold = 2min25sec.

Breath hold with one set of breathing exercises = 3min30sec.

I used to try and get my SAC rate down, then I started getting headaches and decided that the CO2 retention was no good and a bigger tank was a better solution to wanting a longer dive.

My goal now is to keep my normal SAC rate between 0.75 and 1.0. My deco should be cleaner that way and my headaches are a thing of the past.

I'm just sitting here waiting for someone to go in to Shallow Key Board Black Out.

shallow keyboard black........................................


what? did someone say something?

 

[gurumasta]

what are the dangers of smoking and diving. i smoke, and it is really hard to quit, is there any real danger outside of deco diving? is there any danger in deco diving?

In a recent thread somebody posted:

"back before i quit smoking, i consistely had sacs in the .45 area

once i quit, shot up to .8 and above"

i'm wondering if there's anything to this? maybe if a large male reduces his lung capacity to that of a small female by smoking heavily, then his SCR could also fall to that of a small female as well... or is it just a relaxation thing? nicotine gum?

Yup if it happed to them then by all means this must be true and we should all start smoking right away:shakehead

again... what a terrible logical fallacy this is

funny thing is, the ONLY people saying this are non-smokers

to clarify: to state that smoking lowers your SAC is not equivalent to saying
we should all smoke. nobody has made that argument. read the thread.

Yup I agree really I think every one should start, I am sure this will improve our sac. rates:lol:

 

[H2Andy]

you're making an ideological argument

just because smoking is bad for you does not mean that it doesn't lower your SAC

sorry to say, that appears to be the case
