Nitrox Not Helping With Narcosis... It's not making sense.

[JohnN]

Suppose I drank four shots of Jack Daniels and took two hits of of a good green bud.

Now what if instead I drink only three and a half shots of Jack Daniels and took three hits of bud.

I think this calls for more testing

I just posted two studies that show the narcotic effect of oxygen...

so who is this mystery doctor? and what studies did he site to support his claim? We're all on the edge of our seats...

The Dr. call me back. His credentials are without question: one of first 100 from NOAA to start teaching Nitrox; he designs and builds hyperbaric chambers and submarines; his business in hyperbaric medicine and therapy. Here's what he had to say:

Oxygen has no narcotic effect on divers at depth, in the chamber, or anywhere else. It does have a toxic effect, when breathe at increased pressure but no narcotic effect whatsoever. I asked this question in several different ways, I even quoted from my SSI Nitrox manual... he laughed. He reiterated, it has absolutely no narcotic effect. He said there is no such thing as O2 narcosis.

Furthermore, I told him about the controversy on SB of Nitrox displacing nitrogen...could it be argued that a diver is less likely to get narced. He stated technically the point is correct, but the amount of N2 it displaces is a very small percentage, and therefore, a diver could still get narced on Nitrox. I asked, but technically a diver is less likely to get narced on Nitrox than air because it displaces N2, he said, technically yes.

I asked him, since O2 toxicity effects the CNS could it, at higher ata, have an effect like aspirin. He stated that it's very minimal, and a patient is likely to suffer a grand mal sezuire beforehand.

He said that, whomever I'm discussing this with is probably confusing O2 toxicity with narcosis. Oxygen is not narcotic.

I'm just relaying what he told me. If you msg me, I'll provide you with his credentials.

Provide his credentials publicly. I want to speak to him.

one study was about co2 and the other sugested that 02 may contribute.

well ya, you can't "prove" anything in real science. They both show that oxygen is a player in narcosis. Isnt that what this thread is about?

 

[boulderjohn]

I would indeed like his credentials, and I am asking for them publicly so that I can ask him where he gets his information. You can send it to me as a private message if you don't want to reveal him publicly so that he can become famous for overturning current thinking.

By the way, I teach both nitrox courses and advanced nitrox courses. I am familiar with the material in those texts in regard to this. In my instruction I also teach oxygen toxicity. I am not confusing these terms.

Ah! I have clearly been away long enough that everything about me but my name has been forgotten

I'm an old dude ... I forget lots of things ...

you may be right.
i have never seen a narked diver who didnt have some 02 in the mix.

impressive dive total by the way.
5000 + and you are only 25

I've selected somebody you all know to call the person in question, as I don't want the person in question to be inundated with phone calls from divers. Like I said, you all know the person who's going to make the call. Let this person confirm here, in this thread, that what I say is true.

I will add something he told me. He said he worked with NOAA on micro-bubble research and the use of Nitrox. He stated that using Doppler, they found micro-bubbles on divers using Air but found none on divers using Nitrox.

 

[PfcAJ]

You like that?

I wish it just said infinity dives. For the lulz

I think you're misquoting someone, and its making you look...dumb...
