Hi all,

I've dived my dolphin ccr "kiss style" for a couple of years on air or normoxic trimix diluant for 2 reasons :

- possibility of rebreathing the diluant without getting a too weak fio2 in the loop in case of electronic failure

- possibility of breathing the dil oc in case of loop floading in normoxic figure

but 4 days ago I was lingering arroung 55m on a normoxic mix and i realized that the ppo2 was far too high,

I've never dived an hypoxic diluant, what does it change ?

is it hazardous ?

what is the best fo2 given that i never get deeper then 60.

regards
