breathing O2 after a dive?

Don't get me wrong . . . There is NO question that breathing 100% O2 will wash out your nitrogen faster. And the likelihood of any toxicity from using it at the surface is very low. I just worried that, without doing something like running it through a deco software program, someone wouldn't have any accurate way of knowing how MUCH they had accelerated offgassing, and therefore it wouldn't be a good idea to use it to shorten surface intervals.

I hope that's an oops misquote...?

Weeellll, he would be "scrubbing off" CO₂ also :mooner: but yeah I think he was probably meaning to say N₂

What I'm more worried about is that at 20ft(6m) 100% oxygen would have a ppO₂ of 1.6 (assuming at least you're diving at the coast; i.e. sea level,) and that's the absolute max limit reserved even for emergencies. After 1.6 the probability of showing oxtox symptoms become unacceptable. Not such a smart idea just to go "scrubbing off" excess nitrogen I'd say. :no

MASKING the symptoms of DCS with the green bottle, and CURING the DCS are two very different things. Just thought I would throw that out there since there may be people reading through this thread and have stumbled upon some false information, and didn't know any better.

I would save it for an emergency but O2 is evvective against a hangover also. Maybe when I got to the bar I will wear an O2 Mask with a hose for the drinks added. That way I get properly sunseted and no hangover. Just kidding.....
