Burning the O2 clock

[rjack321]

Off topic...but should this person be doing deco dives,or would I want to buddy with them. There are many things that increase your sensitivity to toxing such as medications etc,but if you are experiencing symptoms then this should be a warning that you got out alive this time,but maybe not the next.

I certainly would be cautious, but on the other hand for all I know she might have:

1. had nausea or something like that a few times on deco,
2. didn't know for sure it was CNS/O2 related,
3. switch to 80% for deco to experiment,
4. seemed better so she stuck with 80% and never had the issue again.

Of all the risky things in cave/deco diving, sticking with 80% because its working for her seems moderate to me.

From what I understand, she also dives air instead of 32% because of sensitivity to O2. I'm not positive, but I think the response was nausea and nothing worse. I know she was diving quite a bit before she left the area and didn't have any more issues with the mixes she chose to dive.
