You do not want to breathe pure oxygen, but welding oxygen can be
substituted for medical oxygen.

I wonder what would happen if you mixed in a little argon.

Thanks,

Or a bit of helium.

Well, helium gives you that funny voice; interestingly, freon (before
the church of ozonism got it banned) makes you sound like James Earl Jones.

I figured argon is of a similar density to air, and wouldn't make you talk
so funny. I've also heard of them using a blend of He and SF6, to adjust
the density for deep diving.

Cheers!

I've never heard of SF6 being used in any breathing gas mixture, just HV
electrical switch gear. Diving with various blends of Oxygen, and
nitrogen and/or helium.
