    I posted this here becuase I think most of you advanced divers may be able to help me with my search. I am looking for data and or information in regards to exposure limits and effects of both CNS and the OTU's for diving. Any help would ge greatly appreciated.

    Thanks

    Do you mean tables quantifying CNS and OTU limits/decay, the theory behind them, or both?

    Most training materials for introductory tech diving courses (like Advanced Nitrox, Recreational Trimix, and so forth) provide tables for quantifying exposure and articulate a procedure for planning dives that maintains exposure below levels deemed acceptable by the course designer.

    There's obviously a lot more to the science than that, of course.

    I want to know how these tables were designed and how they came to conclusions on acceptable levels, what the effects are and in easy terms, just what the hell these are doing to us when we are diving. Just looking for some good source material to read and better understand.

    Are you looking for the tables, or information about the symptoms of oxygen toxicity? There will be some discussion of oxygen toxicity (mostly CNS) in any Nitrox text. You might also find some good reading HERE, in the recommended reading list on oxygen in the Rubicon Foundation archives.

    Previous posts give you access to all of the specifics. My only suggestion is to start with a copy of the "NOAA Diving Manual - Diving for Science and Technology". It is a nice overview, covers a lot, and is quite readable.

    Stay safe.

    Gene's a treasure . . . Not just assembling the recommended reading lists for Rubicon, but writing Wikipedia articles!
