The most common gas tensions measured are oxygen tension (P x O 2), carbon dioxide tension (P x CO 2) and carbon monoxide tension (P x CO). [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 ...
A blood gas test or blood gas analysis tests blood to measure blood gas tension values, it also measures blood pH, and the level and base excess of bicarbonate.The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries.

The sealed syringe is taken to a blood gas analyzer. [8] If a plastic blood gas syringe is used, the sample should be transported and kept at room temperature and analyzed within 30 min. If prolonged time delays are expected (i.e., greater than 30 min) prior to analysis, the sample should be drawn in a glass syringe and immediately placed on ...
P A O 2: Alveolar oxygen tension, or partial pressure: P a CO 2: Arterial carbon dioxide tension, or partial pressure: P A CO 2: Alveolar carbon dioxide tension, or partial pressure: P v O 2: Oxygen tension of mixed venous blood: P (A-a) O 2: Alveolar-arterial oxygen tension difference. The term formerly used (A-a D O 2) is discouraged. P (a/A ...

P a O 2 can be obtained from the arterial blood gas analysis and P A O 2 is calculated using the alveolar gas equation. [8] An abnormally low hematocrit (volume percentage of red blood cells) may indicate anemia. X-rays or CT scans of the chest and airways can reveal abnormalities that may affect ventilation or perfusion. [95]
