| 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) |
| respiratory region of tunica mucosa of nose | The area commencing at the vestibule of the nose lined with respiratory mucosa; with the exception of the olfactory mucusa, it includes the entire nasal cavity. Synonym: regio respiratoria tunicae mucosae nasi, respiratory region of tunica mucosa of nose. (05 Mar 2000) |

| respiratory sound | A murmur, bruit, fremitus, rhonchus, or rale heard on auscultation over the lungs or any part of the respiratory tract. (05 Mar 2000) |
| respiratory sounds | Any sound emanating from any portion of the respiratory tract, especially those heard on auscultation; includes breath sounds. (12 Dec 1998) |
| respiratory syncytial viruses | A group of viruses in the pneumovirus genus causing respiratory infections in various mammals. Humans and cattle are most affected but infections in goats and sheep have also been reported. (12 Dec 1998) |
