Subject: How much O2 does the body need in terms of actual disolved O2 per second?

If the Lungs were shut down or removed competely, how much oxygen would 
the blood stream need to carry in order to sustain life? I tried looking 
for information on heart and lung bypasses and found nothing. Also, do 
red  blood cells absorb O2 simply by aeration, or do they need additional 
help? Is it possible to remove your lungs and directley aerate the 
bloodstream by mechanical methods? (h202, compressed O2 or LOX?)This could 
have some advantages for diving.
