Brian is correct. They run the capsules at lower pressure
so that they don't have to make the skins as thick and can
reduce overall weight.
Humans also breath to bring in oxygen as well as to exhale
CO2. It is kind of a dual purpose.

Never heard of the lower pressure before. I
thaught humans breath
because of the buildup of co2. So lowering the pressure and just using
oxygen wouldnt help much would it? Besides 100% oxygen makes things
that are normally low combustible highly combustible.
Take a cubic meter of air at STP. Remove all the non-essential gasses,
leaving only the oxygen behind. You'll end up with same amount of
oxygen necessary to support human life, but the overall pressure will
be lower owing to the lack of those useless gasses.
Well, that's my educated guess at least.
