SAFETY WARNING
If it isn't air it has to be mixed by someone, 'cause it ain't natural.

Perfectly stated. Anything containing gas that isn’t pure air/oxygen/argon or anything else you’d have in a tank is a mixed gas.
LOL. It would have been better to call it "deriched air," since the point is to have less N2 in it.I prefer the term they now use, enriched air. Mixed gas means a gas has been added that wasn't there before.
