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. [1]
The blood can also be drawn from an arterial catheter. An ABG test measures the blood gas tension values of the arterial partial pressure of oxygen (PaO2), and the arterial partial pressure of carbon dioxide (PaCO2), and the blood's pH. In addition, the arterial oxygen saturation (SaO2) can be determined. Such information is vital when caring ...
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) O 2: Alveolar-arterial tension ratio; P a O 2:P A O 2 The term ...

Between 1698 and 1731, some people from the northern and central regions of Vietnam moved to Hóc Môn to escape the constant warfare between the Nguyễn and the Trịnh. At that time, this area was still undeveloped land, with wild animals including tigers roaming free.
Arterial blood (PaO 2) 98-95: Oxygen must cross the alveoli, leading to a drop in PO 2 called the alveolar-to-arterial gradient (typically a drop of 1-5 mmHg, but sometimes larger). [1] [3] Venous blood (PvO 2) 40-35: Arterial blood offloads oxygen in the capillaries before flowing into the venous system.
