Hi all, Chris Hellas sent the following post to my CompuServe address and asked that I post it on techdiver. Apparently he is having difficulty with his mailer, which he should have fixed soon. If you want to reply, please do it directly to Chris (100422.2334@co*.co*). Here's the message: **************** From Chris Hellas To Techdiver On the subject of the use of argon as dive gas element Andy Kerslake wrote:- >>I've spoken to one individual who's tried using Argox. Apparently Argox is ideally suited to deco, however the Argon element is extremely narcotic. The individual concerned likened the effect to drinking a bottle of whisky. This does not sound like a good idea ? Any other views>> I tried in vain to extract information from various Diving Physiologists on the subject of Argonox as a decompression gas to no avail, It would seem as though I had asked the wrong question on a taboo subject. The 'ABYSS' deco software claimed to account for argon usage ( Jump in here Chris if you want ), but I could not find any real information. I spoke to Sheck Exley @ Tek in 1994 on the whole subject and he expressed a similar interest in it's use. The concept was one of intermediate decompression gas use, in that the density of the Argon as the inert gas element would allow a high offgas gradient without causing O2 toxicity problems. The downside is one of potential ongassing of the argon, and possible narcosis problems. Coming to a halt on the information search was a little frustrating, but I managed to chat with Jim Bowden @ Tek 95 following his presentation on the work in Zacaton and the potential to bottom it in 1000ft +..... Jim said that Sheck was pro-Argonox for decompression purposes and had used it on a couple of dives with no real problems. The schedule used was Dr X, and the Argonox part of the schedule was treated as air for any decompression calculations ( not sure of any programmed safety factor in the software generated tables, but I am in thre processof writing to Jim and will post any news). This really covers the extent of any information I have to date, but I, like many others would appreciate any further input on the subject. P.S...Then there's the subject of Neox!.
