Having an MD publish a paper is not going to hack it! U have ample proof of that. As for the tenets of O2 toxicity. Limiting disc to pulmonary O2 tox. It is possible to exceed, w/i reason, the 'safe pulmonary dose' guidelines w/o out long term ill effects. It is just a matter of the amount of the discomfort one is willing to put up w/. (Paranthetically the jury is out on the true long term effects - the carcinogenic effects of free radicals). It is also possible to change the threshold of the ill effects of HBO or prolong the latent period w/ mediactions that scavenge free-radicals, the agents currently held to B causal in oxtox. Nutrients additives have also been suggested. As stated above it is thought tht it is the excessive free radicals produced w/ HBO tht R the cause of the pathogenesis. The enzymes involved in scavenging, like SOD, R considered induceable enzymes, meaning that their titer increases as [substrate] increases. Though this may not reduce the [free radical], it will tend to maintain a steady state, thus delaying overt symptomalogy. Still, it is also incontravertible that many if not all divers, WKPP divers included, do report 'chest burning' when exposed to protracted deco w/ high ppO2. Maneouvers like air breaks do ameliorate this but do not show up in the stnd OTU calculations wh/ require a 24 h break before the pulmonary clock is set to 0. Thus the calc values R artificially elevated relative to actual expo values. New data always becomes available. The validity of the data depends on not who publishes it but whether it can B reproduced by an independent investigator. Obviously all the details of the protocols used to generate the data have to B made avialble for that to happen.
