Dilutional hypoxia....this is a new one for me. I understand it, but I'd never previously considered it...it will require some time to fully digest the implications. Off the cuff; another advantage for trimix over heliox????? > I would suggest that if the PIO2 never exceeds 1.6 bar, that "air breaks" > are not critical (please do not try this at home), particularly during this > early stage of the hyperbaric oxygen exposure. What about 4-hour+ rebreather dives at relatively constant PO2?
