Best Answer

This is calcium peroxide. You have to be careful... one might be tempted to call this calcium oxide, but oxygen normally has a charge of 2-, and since Ca always forms Ca2+, this is not calcium oxide because its formula would be CaO (Ca2+ and O2-). So the anion here is O22-, which is the polyatomic anion peroxide.

The above response may be what you're looking for, but being in the medical profession, I see CaO2 as the formula to calculate Content of arterial oxygen. Therefore, the formula for this is:

(Hb x 1.34 x %SaO2) + (PaO2 x 0.003)

PaO2 should be in decimal form, PaO2 you can obtain from the ABG.
