wp mosmed is the manual of style for articles that come under any of the medical categories all medical related articles have to comply to reach good article ga or above hehe i only found out about it at the second ga review try typing 'paul bert' into the search box in the left column of any page and click the 'search' button rather than pressing enter or clicking the go button you'll get the search results the article paul bert is first and oxygen toxicity is fourth if you click the go button instead you go direct to the article if it exists otherwise you get the search results as before try the same test searching for 'paul bert effect' there is an article on decompression sickness we plan to tackle that after we have finished getting nitrogen narcosis to ga no need to mention those in oxygen toxicity although all of them are summarised in scuba diving effects of breathing high pressure gas the partial pressure of oxygen is the trigger for oxtox that is found by multiplying the fraction of oxygen by the ambient pressure at the depth you're at for example air is oxygen and the pressure at metres is bar so you have a partial pressure of oxygen ppo of x bar that's safe from cns oxtox as it's never been observed at less than bar divers may use gas mixtures different from air however take a look at nitrox for more information it's my pleasure to try to explain where i can i must admit it was a little mischievous of me to throw you in at the deep end on oxygen toxicity but believe me the discipline needed to meet all the style requirements is a great learning experience and worth the effort by the way hyperoxia is linked but to its dictionary definition in wiktionary like this wikt hyperoxia with a pipe to give this hyperoxia let me know if there's any of that you didn't understand cheers
