- This is generally accepted as true, but there appears to be some rumblings
- within the UHMS that higher concentrations (fractions) of O2 may cause
- higher susceptability to CNS O2 toxicity. In other words, breathing pure
- O2 at 20 FSW (PO2=1.6 ATAs) may be riskier than diving to 218 FSW on air
- (PO2=1.6 ATAs) if all other circumstances are equal. As far as I know, there
- is nothing published on this - it was just TALK during a seminar I attended
- on in-water Oxygen Decompression. Anybody heard anything else?
