Please give me your pO2 opinion

[PfcAJ]

I've always found the CNS% thing to be BS. You can tox well below it, and not tox well past the "100%" value. So uh.... wat do?

 

[fdog]

I agree with the angst over the extreme variability with CNS% and ppO₂.

Still, in all the data (what little there is, anyway) there has to emerge a TC_Lo and TD_Lo.*

I would think the prudent diver would stay under these values, where you'd have the least chance of an event; but on reflection, where one places one's self in relation to TC_Lo is a matter of personal philosophy.


All the best, James



*: TC_Lo = Toxic Concentration Lo, the lowest concentration of a material known to cause a toxic reaction. Even just getting a headache would qualify as a toxic reaction. TD_Lo = Toxic Dose Lo. TC_Lo would best equate to ppO₂, and TD_Lo for CNS%.

Done.
