3. What is PaO2?

PaO2 is the partial pressure of oxygen in the blood that represents the overall oxygen content. It is different from SaO2 and SpO2 in that it measures how much oxygen is present, rather than the saturation of the oxygen-carrying hemoglobin molecules. "Partial pressure" is a standard term used for gas mixtures and identifies a single gas component.
