Thanks, I guess you were.
Certainly none of the studies I have read so far have sugested or even mentioned the possibility that an (O2) toxing person would stop breathing after the convulsion phase. Just wanted to double check I wasnt missing something.
"It has been shown repeatedly that apart from the associated hazards of physical injury or drowning, a single oxygen convulsion does not produce harmful or residual effects" Clark and Thom, 'Oxygen Under Pressure' Phys & Med of Diving.
Isn't this the way that medical protocols get refined over time? Adding newly acquired information, filtering noise and possible redefining the existing standard? I don't want to be stepping on your toes but it sounds as if your preferring theory over practice. At the same time you were curious enought to ask for the source so you're not in denial
.
Medical is theory based on empirical data. If you can dismiss of the two incidents because of secondary influences then well OK. If not it could be worthwhile treating the inccidents as a clue in pursuit of refining the protocol. For now it would just be cautious to take the possibility into account...
How? Well that's a different matter. If someone just took the plunge and is toxed right away then a controlled ascent with all measures to prevent barotrauma is not something that I would objected to. For a diver past his NDL it's a different matter I guess and unless we all start diving with black-boxes we might not find the best protocol, just a local optimum.
