>But isn't the CO2 being pulled out of the loop by the absorbent canister?

That brings up an interesting point - can the scrubber pretty much
absorb ALL the CO2 being exhaled, leaving none to return in the input
or does *some* fraction return in the breathing loop?  If so, what
fraction returns, and, is this a function of scrubber lifetime (i.e.
how far along you are in the usable life of the scrubber) AND, what is
the function of time to predict CO2 retention in the loop?

Lots of questions...
