Why I Love Nitrox....

Ok, this has pretty much nothing to do with Mike's thread, but when I saw it I couldn't help but post it

So do you shorten the dive or extend it with this stuff?

Thanks for setting me straight, Joel.......far be it from me to argue with the author of a section of the NOAA Manual! LOL!

Actually, I'm open to debate and counter-point....that was the whole point of my post [note where I said: "Feel free to disagree and tell me it's all in my head"], so thanks for contributing.

PS: I am intrigued about the 'narcotic properties' of oxygen.....can you refer me to further references on it?

Mikey

Oxygen under pressure produces symtoms similar to that of nitrogen narcosis. Including, visual disturbances, euphoria, tinitus, twitching, etc. Also oxygen's physical properties are similar in nature to that of nitrogen ie: density etc.

Chamber tests have produced similar impairments with high pressure oxygen.

Oh and the setting you straight thing was in jest!

Cheers

Matt, extending the...dive... is always a good thing

So your in the market for a rebreather too? Anyone else?

This simple comparison shows how using just 7% less nitrogen in a mix will decrease decompression by more than 30 minutes. This is signficiant.

What would the times be if the dive was on air with the deco on nitrox?

SoCalDiveGirl,


Uerika!!! you have found the magic potion for us die hards(!)

Zero,

Why would you consider the dive on air, if you would do the Deco on EAN? You are already investing in the EAN gas, so there is no additional expense. I do alot of tri-mix, with deco on 50% and 100%, and I can not even recall the last time I used air. I FIRMLY believe in the use of a gas that allows me an additional measure of saftey. EAN is not the " be all and end all" of magic gas, but it does afford me better options when diving.

IF you used air for bottom mix and EAN 50 % from 70 fsw on up for the decompression phase the total deco would be 55 minutes. Just about a minute more. However you have now added some complexity to the dive. I know its not much but you have added another cylinder, regulator etc.

Well planned nitrox dives can be used effectively without complication.
