Blood gas tension

Blood gas tension refers to the partial pressure of gases in blood.[1] There are several significant purposes for measuring gas tension.[2] The most common gas tensions measured are oxygen tension (PxO2), carbon dioxide tension (PxCO2) and carbon monoxide tension (PxCO).[3] The subscript x in each symbol represents the source of the gas being measured: "a" meaning arterial, "A" being alveolar, "v" being venous, and "c" being capillary.[3] Blood gas tests (such as arterial blood gas tests) measure these partial pressures.
