Why Argon is much more narcotic than helium or nitrogen?

[Hari Seldon]

I was speaking with some friends about trimix and it's come up this question...someone have a consistent answer?

 

[VooDooGasMan]

just google argon narcotic affects, or gases underwater, youll find it somewhere.

 

[JeffG]

Its the color.

 

[JeffG]

or maybe the odor?


oh well...there goes that consistency thing

Narcosis seems to be associated with the solubility of the gas in fats. The lipid solubility of argon is higher than that of nitrogen and much higher that that of helium.

Of course, with your specialty being Psychohistory, I wouldn't expect you to necessarily know that.

Can the greater molecular weigh of Argon affect the phenomenon?

hihi...unfortunately Psychohistory don't treat about gas

just google argon narcotic affects, or gases underwater, youll find it somewhere.

I've found a great amount of informations about narcosis effects but not about the causes...

In any case, many many thanks for the answers.

Because or Trimix manuals tell us it's more narcotic.

"Argon is highly soluble and heavier than nitrogen, and thus a very poor choice."
Technical Diving in Depth, Bruce R. Wienke... pg.70

Umm, Hari,

just google argon narcotic affects, or gases underwater, youll find it somewhere.

That wasn't me, it was VooDooGasMan.

Can the greater molecular weigh of Argon affect the phenomenon?

I have absolutely no idea what affects it.

Uh, ehm, er ... sorry, Psychohistory don't treat neither about "Quote" ...

If you are looking for the actual chemical mechanism of narcosis, it is not known. We don't even really know how anesthetic gases work, although we know what kinds of structures are associated with anesthetic properties.
