Thats neat and everything but you would still have to get rid of the carbon dioxide in your bloodstream somehow.

 

[Graylin]

Would CO2 bubbles form in your alveoli as the concentration increases in the blood? In that case, you could exhale the CO2 as it builds up in your blood, just as usual.

I'm no doctor or physiologist but I believe the hemoglobin in your blood needs to chemically bond with Oxygen molecules in exchange for carbon dioxide, it can't just shed CO2 voluntarily. Having an injection of an O2 solution into your bloodstream could theoretically replace aspiration but I am skeptical of the idea of our lungs just spontaneously filling up with CO2 to be exhaled. Maybe someone with a stronger background in biology or anatomy can explain how this would work.
Try exhaling as much air as you can, then wait and see if the air pressure in your lungs starts to build from CO2 production, I don't think it does. The CO2 just remains in your bloodstream until you become hypercapnic and involuntarily gasp for air.

It's actually much more complicated than what the author makes it sound. I would bet this is still quite a ways out from being approved for use on humans.
