Richard, I missed something somewhere in there.

It is my understanding that a fully-closed-circuit rebreather has to
compensate for respiration of oxygen into carbon dioxide and for ascents
and descents.  I sort of had the idea somewhere that the former required an
oxygen sensor, because you (a) don't want to wind up with a counterlung
full of diluent and you (b) don't want to push your ppO2 over 1.4 ATA or
so.

How does the MkV get around this?  Or what is it doing that it can be said
that it is not dependent on electronics?
