Oh yes you can, panorama Nova FFM, just breathe through your nose to get OC gas, no lever to turn as with a BOV

I meant with a seperate reg or autoair type device.... anyway nose breathing on a FFM is cheating

and you won't be inclined to do it with a mouthful of CO2 loop or caustic cocktail I'd wager...
Maybe someone should invent the AutoBOV, it switchs to OC when it detects low or high PPO2, and increase in CO2 or caustic goo flooding the inhale hose!
