Definition: When measuring arterial blood gases, you will sometimes hear the term partial pressure of oxygen, or Pa02. Partial pressure refers to the pressure exerted by a specific gas in a mixture of other gases. Pa02, put simply, is a measurement of oxygen in arterial blood.

The range of normal for Pa02 is 75 - 100 mm Hg. If your Pa02 is less than this, it means you are not getting enough oxygen.
