Nitrogen Narcosis Effects

[mrobinson]

Recently a new buddy, who is for more into techincal training than I, told me that the hard effects of narcosis is more due to how you've been sleeping, what you eat, how hydrated your are, etc. Can anyone build on that more?

(When I say hard effects, I mean the "common" feelings of narcosis due to the nitrogen absorbtion effect.)

your muscle memory of how long it takes to check a gauge could be perhaps 2 seconds, it may be that when narced, your brain absorbs the information in longer than that. So you have checked your gauge, computer timer etc, but you have no clue what it said..

that has happened to me on very deep dives

Yes, I think each dive is different. On a recent dive at 45m my wife complained of feeling very tired at depth while I noticed my reactions were very, very slow. Each time I went to look at my gauges I noticed that when I looked up again the scenery around me and my wife's relative position had changed. I was obviously taking about 10secs + to absorb what would normally just take a glance. I was registering well because I was able to remember clearly afterwards the profile and the depth at which I shot each photo on the wall.
