| respiratory mechanics | The physical or mechanical action of the lungs, diaphragm, ribs, and chest wall during respiration. It includes airflow, lung volume, neural and reflex controls, mechanoreceptors, breathing patterns, etc. (12 Dec 1998) |
|---|---|
| respiratory metabolism | The exchange of respiratory gases in the lungs, oxidation of foodstuffs in the tissues, and production of carbon dioxide and water. (05 Mar 2000) |
| respiratory metal | A metal present in certain respiratory pigments; e.g., iron, manganese, copper, vanadium. (05 Mar 2000) |
| respiratory minute volume | The minute volume of breathing; the product of tidal volume times the respiratory frequency. See: pulmonary ventilation. (05 Mar 2000) |
| respiratory mucosa | Pseudostratified ciliated columnar epithelium with goblet cells and a lamina propria containing, in addition to connective tissue, numerous seromucous glands and in some regions many thin-walled veins which line the airways. See: region of respiratory mucosa. (05 Mar 2000) |
| respiratory murmur | The respiratory murmur heard on auscultating over the normal lung. Synonym: respiratory murmur, vesicular murmur. (05 Mar 2000) |
| respiratory muscles | These include the muscles of the diaphragm and the intercostal muscles. (12 Dec 1998) |
| respiratory pause | Cessation of air flow for less than 10 seconds. See: sleep apnea. (05 Mar 2000) |
| respiratory physiology | Functions and activities of the respiratory tract as a whole or of any of its parts. (12 Dec 1998) |
| respiratory pigments | The oxygen-carrying (coloured) substances in blood and tissues (haemoglobin, myoglobin, haemocyanin, etc.). (05 Mar 2000) |
| respiratory poison | A compound that inhibits the respiratory chain. Synonym: respiratory poison. (05 Mar 2000) |
| respiratory protective devices | Respirators to protect individuals from breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors. (12 Dec 1998) |
| respiratory pulse | Waxing and waning of any pulsation produced by respiration. (05 Mar 2000) |
| respiratory quotient | <physiology> Molar ratio of carbon dioxide production to oxygen consumption. (18 Nov 1997) |
| respiratory rate | The number of breaths per minute (or, more formally, the number of movements indicative of inspiration and expiration per unit time). In practice, the respiratory rate is usually determined by counting the number of times the chest rises (or falls) per minute. By whatever means, the aim is to determine if the respirations are normal, abnormally fast (tachypnea), abnormally slow (technically termed bradypnea), or nonexistent (apnea). (12 Dec 1998) |
