Blood gas tension Blood gas tension Blood gas tension refers to the partial pressure of gases in blood. There are several significant purposes for measuring gas tension; the most common gas tensions measured are oxygen tension (PO), the carbon dioxide tension (PCO) and carbon monoxide tension (PCO). The subscript "x" in each symbol represents the source of the gas being measured; ""a"" meaning arterial, ""A"" being alveolar, ""v"" being venous, ""c"" being capillary. Blood gas tests (such as arterial blood gas tests) measure these partial pressures. PO – Partial pressure of oxygen at sea level (765 mmHg) in arterial blood is between 75
Blood Car Blood Car Blood Car is a 2007 black comedy film set in the not-too-distant future where gasoline prices have become exorbitant ($30+ US/gallon). Things take a turn for the worse when a kindergarten teacher (Mike Brune) invents a car that runs on a different fuel source: blood. Archie Andrews is a vegan kindergarten teacher who buys products from Lorraine's vegetarian road side stand. He is developing an engine that runs on wheatgrass with no results until he accidentally cuts his finger and the blood falls in the wheatgrass, which filters to the engine and then causes it to run.
