I’m not a biologist, doctor, or chemist, but my guess is “no.” We have evolved to use oxygen to create energy within our cells, not some other gas.

I would hazard an additional guess that it’s not a simple matter to just swap out the oxygen molecules for something else. Carbon monoxide binds better and more readily to our cells, yet that mixture would asphyxiate you.

The cells need this oxygen to make the energy your body needs to work. When cells make that energy, they create the waste product carbon dioxide.
