| mustard gas | <chemical> 1,1'-thiobis(2-chloroethane). Severe irritant and vesicant of skin, eyes, and lungs. It may cause blindness and lethal lung oedema and was formerly used as a war gas. The substance has been proposed as a cytostatic and for treatment of psoriasis. It has been listed as a known carcinogen in the fourth annual report on carcinogens (ntp-85-002, 1985) (merck, 11th ed). Pharmacological action: carcinogens, chemical warfare agents, dermatologic agents. Chemical name: Ethane, 1,1'-thiobis(2-chloro- (12 Dec 1998) |
| 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) |
| pulmonary gas exchange | The exchange of oxygen and carbon dioxide between alveolar air and pulmonary capillary blood. (12 Dec 1998) |
| 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) |
