Dr Chris Pizzo measured his alveolar PO2 at the top of Everest at 0.05B during the American Medical Research expedition in 1981. I appreciate that acclimatisation plays a part but why doesn't the diving reflex allow me to endure such a low PO2 when diving?

Comments on Rebreather World suggest it is possible to endure significantly higher PO2s than 1.6 for a limited period, and that the oxygen clock has little to do with CNS toxicity. What are the real limits on the high end?

No nanny comments please: I have no death wish - I merely seek knowledge!
