Blood fuel tension refers to the partial strain of gases in blood. There are several significant functions for measuring fuel tension. The most common fuel tensions measured are oxygen tension (PxO2), carbon dioxide tension (PxCO2) and carbon monoxide tension (PxCO). The subscript x in each image represents the source of the fuel being measured: "a" meaning arterial, "A" being alveolar, "v" being venous, and "c" being capillary. Blood gas checks (equivalent to arterial blood gas checks) measure these partial pressures. PaO2 - Partial strain of oxygen at sea stage (160 mmHg (21.Three kPa) within the atmosphere, 21% of the usual atmospheric pressure of 760 mmHg (one zero one kPa)) in arterial blood is between 75 and 100 mmHg (10.0 and 13.Three kPa). PvO2 - Oxygen tension in venous blood at sea level is between 30 and 40 mmHg (4.00 and 5.33 kPa). Carbon dioxide is a by-product of food metabolism and in excessive quantities has toxic results together with: dyspnea, acidosis and altered consciousness.
