| breath | 1. The air inhaled and exhaled in respiration, air which, in the process of respiration, has parted with oxygen and has received carbonic acid, aqueous vapor, warmth, etc. "Melted as breath into the wind." (Shak) 2. The act of breathing naturally or freely; the power or capacity to breathe freely; as, I am out of breath. 3. The power of respiration, and hence, life. "Thou takest away their breath, they die." (Ps. Civ. 29) 4. Time to breathe; respite; pause. "Give me some breath, some little pause." (Shak) 5. A single respiration, or the time of making it; a single act; an instant. "He smiles and he frowns in a breath." (Dryden) 6. That which gives or strengthens life. "The earthquake voice of victory, To thee the breath of life." (Byron) 7. A single word; the slightest effort; a triffle. "A breath can make them, as a breath has made." (Goldsmith) 8. A very slight breeze; air in gentle motion. "Calm and unruffled as a summer's sea, when not a breath of wind flies o'er its surface." (Addison) 9. Fragrance; exhalation; odour; perfume. "The breath of flowers." (Bacon) 10. Gentle exercise, causing a quicker respiration. "An after dinner's breath." (Shak) Out of breath, breathless, exhausted; breathing with difficulty. Under one's breath, in low tones. Origin: OE. Breth, breeth, AS. Br odour, scent, breath; cf. OHG. Bradam steam, vapor, breath, G. Brodem, and possibly E. Brawn, and Breed.

| breath analysis test | A test of hepatic and intestinal absorptive function; aminopyrine labelled with radioactive carbon is administered orally; expired 14CO2 is a measure of aminopyrine absorption and its metabolism in the liver; a measurement of the amount of 14CO2 exhaled after an oral dose of 14C-O-xylose; a measurement of exhaled hydrogen gas following an oral dose of lactose as a test of lactose deficiency. (05 Mar 2000) |
| breath-holding | Voluntary or involuntary cessation of breathing; often seen in young children as a response to frustration. (05 Mar 2000) |
| breath-holding test | A rough index of cardiopulmonary reserve measured by the length of time that a subject can voluntarily stop breathing; normal duration is 30 seconds or more; diminished cardiac or pulmonary reserve is indicated by a duration of 20 seconds or less. (05 Mar 2000) |
| breath tests | Any tests done on exhaled air. (12 Dec 1998) |
| shortness of breath | Difficulty breathing. (27 Sep 1997) |
| uraemic breath | Characteristic odour of the breath in patients with chronic renal failure, variously described as "fishy," "ammoniacal," and "fetid," which is indicative of the systemic accumulation of volatile metabolites, usually excreted in the urine; dimethylamine and trimethylamine have been identified and correlated with the classic fishy odour. (05 Mar 2000) |
| urea breath test | A test for the presence of the bacteria helicobacter pylori that causes inflammation and ulcers in the stomach. The breath test is based on the ability of h. Pylori to break down urea. Ten minutes after swallowing a capsule containing urea with labelled carbon, a breath sample is collected to detect labelled carbon in the exhaled breath. A positive test indicates active infection. The test turns negative after eradication of the bacteria from the stomach with antibiotics. (12 Dec 1998) |
| liver breath | A peculiar odour to the breath in persons with severe liver disease; caused by volatile aromatic substances that accumulate in the blood and urine due to defective hepatic metabolism. Synonym: liver breath. (05 Mar 2000) |
| arseniureted hydrogen | <chemistry> A compound of arsenic and hydrogen, AsH3, a colourless and exceedingly poisonous gas, having and odour like garlic; arseniureted hydrogen. Origin: From Arsenic. Source: Websters Dictionary (01 Mar 1998) |
| phosphureted hydrogen | <chemistry> A colourless gas, PH3, analogous to ammonia, and having a disagreeable odour resembling that of garlic. Synonym: hydrogen phosphide, and formerly, phosphureted hydrogen. It is the most important compound of phosphorus and hydrogen, and is produced by the action of caustic potash on phosphorus. It is spontaneously inflammable, owing to impurities, and in burning produces peculiar vortical rings of smoke. Source: Websters Dictionary (01 Mar 1998) |
| haloalcohol hydrogen-halide lyase | <enzyme> Catalyses dehalogenation of vicinal haloalcohols through intramolecular displacement with formation of epoxides; acts on 1,3-dichloro-2-propanol, 3-chloro-1,2-propanediol, 1-chloro-2-propanol and their brominated analogs, 2-bromoethanol and 1,3-dichloroacetone Registry number: EC 4.5.1.- Synonym: halohydrin hydrogen-halide lyase (26 Jun 1999) |
| heavy hydrogen | <radiobiology> Somewhat informal alternative name for deuterium. See: deuterium. (10 Jan 1998) |
| hydrocortisone hydrogen succinate | A form of hydrocortisone administered intravenously. (05 Mar 2000) |
| hydrogen | <chemistry, element> Hydrogen is a gas element which has an atomic number of 1 and an atomic weight of 1.0079. It combines with oxygen to form water (H20) and is present in all organic compounds. A few types of bacteria can metabolise atmospheric hydrogen (H2). Hydrogen gas itself is not poisonous, but when it mixes with air it can easily ignite or explode. Hydrogen was discovered by Henry Cavendish in 1766 and was named by Lavoisier. There are two main isotopes of hydrogen: deuterium (2H) and tritium (3H, which is radioactive and is used in some glow-in-the-dark paints and as a tracer in biological studies). Abbreviation: H (09 Oct 1997) |
