Is O2 satsor O2 stats correct?

I will guess you are talking about measuring oxygen saturation with an oximeter?

This would be O2 sat or sats, as in saturation. Many, many people do say O2 stats. As is statistics, or possibly status. It is a single number, therefore it is not ever statistics, a plural. And status isn't really shortened that way, and a single O sat does not equate a status. Now if you are talking about ABGs...

Pet peeve of mine. :) Thanks for asking
