How To Experience Narcosis With Minimal Risk?

They can be, but not in this discussion, the regs deliver:
The issue is rapid shallow or rapid deep breathing.

Nice benign, confined warm-water pool --135 divers statically breathing off one first stage . . . very interesting yet trivial example & argument.

How practical & applicable was that for real world diving?

:sigh:

I give, Kev. Yes, in a cold dark-narc stress situation the reg won't hold up to the demand.

-over and out.

What a dumb and useless comment. Really.

The point, of course, is the reg can handle a LOT of breathing, which is a separate issue from whether some individual wishes he had more air. The reg is showing that even 135 people can't over breathe it......what is your problem with this?

Fair enough lowviz ;-D

It's nice to know my Mk25 can handle 135 static divers in a warm water pool, even though it could not help rid my CO2 retention -even on the surface in rough sea state & swell conditions.

Because it's a trivial gimmick "exhibition" with no value to real world diving, or to the topic of this thread. . .

I totally disagree. You are correct that a person can hyperventillate and shallow-breathe and not get enough oxygen to clear out CO2, and that the CO2 build-up can greatly exacerbate the onset and intensity of narcosis. But the problem is not the regulator, which is what the demo you dismiss shows, the problem is the diver. "Overbreathing" the reg is a semantic misnomer; it would be more accurate to call it "underusing" the reg. The gas is there....just take deep breaths, slowly....

The problem is with you as the biological system, not the brass and rubber.

Steve and I are at odds at the moment, but that doesn't prevent me from quoting his most intelligent and spot-on blog.

Moot point semantically with regards to this thread: Overbreathing, rapid shallow, inefficient or "underusing" the reg --from a Pathophysiological perspective, the result is the same --CO2 Retention potentially leading to acute Hypercapnia.

And there is not a "problem" with the diver per se: just the natural & understood physiological limitations of the Cardiorespiratory System and the general physical & exercise tolerance of the human body under exertion in wet open water hyperbaric conditions. Even an Olympic world class swimmer would overbreathe a regulator in a few minutes attempt at finning against a strong current. . .

You really are a POV warrior. You know that, don't you?

From Wikipedia:
"Calling a spade a spade is sometimes referred to as "the duck test" after the aphorism If it looks like a duck, swims like a duck and quacks like a duck, it's probably a duck....

However, ducks are funny in that they rarely believe they are ducks. A humane way to communicate with an anatid that you believe to be a duck would be to calmly inform it of its duck-like behavior. Shouting "IT'S A DUCK" is likely to excite the duck, and it may quack at you, and when you're in a shouting match with a duck, no one really wins."
