nitrous oxide

nitrogen (I) oxide,

chemical compound, N₂O, a colorless gas with a sweetish taste and odor. Its density is 1.977 grams per liter at STP. It is soluble in water, alcohol, ether, and other solvents. Although it does not burn, it supports combustion since it decomposes into oxygen and nitrogen when heated. The gas is prepared commercially by the thermal decomposition of ammonium nitrate, NH₄NO₃, at about 240&degC; to produce nitrous oxide and water; the reaction must be carefully controlled to prevent explosive decomposition of the nitrous oxide. The gas is purified, liquified by compressing and cooling it, and stored in metal cylinders. A major use of nitrous oxide is in anesthesia, e.g., in dentistry. It is commonly called laughing gas since it produces euphoria and mirth when inhaled in small amounts. It is also used in making certain canned pressurized foods, e.g., instant whipped cream. Nitrous oxide was discovered (1772) by Joseph Priestley, who called it "diminished nitrous air"; he prepared it from "nitrous air" (nitric oxide, NO) by treatment with iron powder or a mixture of iron and sulfur powders. Its properties were further studied (1799) by Sir Humphry DavyDavy, Sir Humphry,
1778–1829, English chemist and physicist. The son of a woodcarver, he received his early education at Truro and was apprenticed (1795) to a surgeon-apothecary at Penzance.

Nitrous Oxide

laughing gas, one of the oxides of nitrogen. It is used as medicine in a mixture with oxygen to induce inhalation narcosis in surgical operations and childbirth, and sometimes in myocardial infarction. It was called laughing gas by the English chemist H. Davy, who, while experimenting on himself to study the effect of nitrous oxide (1799), observed excitation in the initial phase, accompanied by laughter and chaotic body movements, and, in the following phase, unconsciousness.

nitrous oxide

[′nī·trəs ′äk‚sīd] (inorganic chemistry) N₂O Colorless, sweet-tasting gas, boiling at -90°C; slightly soluble in water, soluble in alcohol; used as a food aerosol, and as an anesthetic in dentistry and surgery. Also known as laughing gas; nitrogen monoxide.

nitrous oxide

a colourless nonflammable slightly soluble gas with a sweet smell: used as an anaesthetic in dentistry and surgery. Formula: N₂O

nitrous oxide

nitrous

[ni´trus] pertaining to or containing nitrogen in its lowest valence.nitrous oxide a colorless, odorless gas that is a weak inhalational anesthetic, usually used in combination with a potent halogenated inhalational anesthetic to produce anesthesia" >general anesthesia or briefly for dental surgery. Its use as a sole agent requires high concentrations that may cause hypoxia. abuse poses the risk of anoxic death from asphyxia. Popularly known as laughing gas.

ni·trous ox·ide

(nī'trŭs oks'īd), N₂O; a nonflammable, nonexplosive gas that will support combustion; widely used as a rapidly acting, rapidly reversible, nondepressant, and nontoxic inhalation analgesic to supplement other anesthetics and analgesics; its anesthetic potency alone at normal atmospheric pressure is inadequate to provide surgical anesthesia. Synonym(s): dinitrogen monoxide, nitrogen monoxide

nitrous oxide

n. A colorless, sweet-tasting gas, N₂O, used as a mild anesthetic in dentistry and surgery.

ni·trous ox·ide

(nī'trŭs ok'sīd) A nonflammable, nonexplosive gas that will support combustion; widely used as a rapidly acting, rapidly reversible, nondepressant, and nontoxic inhalation analgesic to supplement other anesthetics and analgesics; its anesthetic potency is inadequate to provide surgical anesthesia.
Synonym(s): laughing gas.

nitrous oxide

A weak anaesthetic and painkilling (analgesic) gas widely used as a vehicle for more potent anaesthetic agents in the maintenance of general anaesthesia. Also known as ‘laughing gas’. The drug is on the WHO official list.

Nitrous oxide

A colorless, sweet-smelling gas used by dentists for mild anesthesia. It is sometimes called laughing gas because it makes some patients feel giddy or silly.Mentioned in: Tooth Extraction

ni·trous ox·ide

(nī'trŭs ok'sīd) Nonflammable, nonexplosive gas that will support combustion; widely used as a quick acting, reversible, nondepressant, and nontoxic inhalation analgesic to supplement other anesthetics and analgesics.
