"If it was 100% oxygen. It wouldn't be nitrox would it. 100% means pure oxygen" - so what does "up to 100% oxygen" mean? --RexxS (talk) 00:28, 28 July 2009 (UTC)[reply]

I had changed that article to say that it was a gas that contained more than 21% oxygen and the remainder consisting of nitrogen. The IP address guy changed to the 100% oxygen thing again. My big theory is really it is a gas just consisting of Oxygen & nitrogen. Look forward to your response.

Thanks for pointing it out any how.

Thanks for the response. I hope you don't mind me copying across your comment from my talk page to keep discussion together. It is difficult to find a good form of words to describe nitrox in the lead of Oxygen toxicity as it's not the main point of the article. However, I did choose my words carefully, since nitrox is not limited to hyperoxic mixes.[1] EAN is indeed defined as that, but nitrox is what is discussed in the body of the article, so "over 21% oxygen" is simply inaccurate. Since the point that I wanted to make was that very high FO2 may be carried by scuba divers in nitrox-labelled, oxygen-clean cylinders, I used the formulation "up to 100% oxygen", rather than the technically accurate, but unnecessarily pedantic "up to, but not including 100% oxygen"; there is no value in mentioning nitrogen in the lead of an article about oxygen toxicity. The IP came up with the nonsense about "up to 36%" and "oxygen toxicity is nearly impossible". I've now restored the original text, but would be happy to discuss better wording if you can find any. --RexxS (talk) 02:49, 28 July 2009 (UTC)[reply]

Nitrox

Bah, I ec'd with your archiving - but I've typed it now, so here goes;

I expect that they were a

PADI diver; I'm a PADI instructor, and we teach using a table that calculates O pp in the range of 32% to 36%, hence they might consider that to be 'Nitrox'. As far as the PADI course goes, 'enriched air' is always within that range. The term itself isn't great; 'enriched air' seems better but Nitrox is quick and easy to say; a diver would consider anything above 21% to be 'nitrox' (ie enriched); if it was <21% it would not be enriched, thus we wouldn't use the term Nitrox. We'd never have that anyway, as it's produced by adding O to air, so we wouldn't be able to make a <21% mix. Anything over 40% is not covered by PADI. I'm not disagreeing with anything, just trying to give the diver perspective, being as I stumbled across this thread.  Chzz  ►  22:31, 21 August 2009 (UTC)[reply
