Dumb question, but in a very oxygen rich environment, can you just breathe through a paper bag or something? Mostly just breathe your own exhaled CO2 with a bit of O2 leaking in?
For short periods maybe. You only use a few percent of the O2 you breathe in each time. But you also increase the CO2 each time. It'd depend on the amount of leak because you need enough O2 coming in but enough CO2 going out.
