| haemolytic gas | A poisonous gas, such as arsine, inhalation of which causes haemolysis with haemoglobinuria, jaundice, gastroenteritis, and nephritis. (05 Mar 2000) |
|---|---|
| producer gas | Fuel gas high in carbon monoxide (CO) and hydrogen (H2), produced by burning a solid fuel with insufficient air or by passing a mixture of air and steam through a burning bed of solid fuel. (05 Dec 1998) |
| second gas effect | When a constant concentration of an anaesthetic like halothane is inspired, the increase in alveolar concentration is accelerated by concomitant administration of nitrous oxide, because alveolar uptake of the latter creates a potential subatmospheric intrapulmonary pressure that leads to increased tracheal inflow. (05 Mar 2000) |
| sewer gas | Gas, probably mostly methane, resulting from decomposition of organic matter in sewers; potentially explosive and toxic. (05 Mar 2000) |
| sneezing gas | A substance, such as a gas, that induces sneezing. Synonym: sneezing gas. (05 Mar 2000) |
| suffocating gas | A gas, such as chlorine or phosgene, that causes intense irritation of the bronchial tubes and lungs, resulting in pulmonary oedema. (05 Mar 2000) |
| ideal alveolar gas | The uniform composition of gas that would exist in all alveoli for a given total respiratory exchange if all alveoli had identical ventilation-perfusion ratios and achieved perfect equilibrium with the blood leaving the pulmonary capillaries. (05 Mar 2000) |
| inert gas narcosis | Progressive mental disturbances and unconsciousness due to breathing mixtures of oxygen and inert gases (argon, helium, xenon, krypton, and atmospheric nitrogen) at high pressure. (12 Dec 1998) |
| inspired gas | Any gas that is being inhaled; specifically, that gas after it has been humidified at body temperature. (05 Mar 2000) |
| intestinal gas | The complaint referred to as intestinal gas is a common one and the discomfort can be quite significant. Everyone has gas and eliminates it by burping or passing it through the rectum. In many instances people think they have too much gas when in reality they have normal amounts. most people produce 1 to 3 pints of intestinal gas in 24 hours and pass gas an average of 14 times a day. It is made up primarily of odourless vapors such as carbon dioxide, oxygen, nitrogen, hydrogen, and in some families, methane. The unpleasant odour is due to bacteria in the large intestine that release small amounts of gases containing sulfur. (12 Dec 1998) |
| intramural bowel gas | <radiology> Pneumatosis cystoides intestinalis, necrotizing enterocolitis (NEC) - infants, mesenteric vascular thrombosis, necrosis due to strangulated obstruction, toxic ulcerative colitis, ulceration proximal to obstructing carcinoma, post-surgical changes (12 Dec 1998) |
| tear gas | A gas, such as acetone, benzene bromide, and xylol, that causes irritation of the conjunctiva and profuse lacrimation. See: lacrimator. (05 Mar 2000) |
| tetanus and gas gangrene antitoxins | A mixture of antibodies obtained from animals immunised against the toxins of Clostridium tetani, C. Perfringens, and C. Septicum. (05 Mar 2000) |
| expired gas | Any gas that has been expired from the lungs; often used synonymously with mixed expired gas. (05 Mar 2000) |
| universal gas constant | <radiobiology> R = 8.314 x 10^7 ergs per degree C per mole. (09 Oct 1997) |
