| bronchial provocation tests | Tests involving inhalation of allergens (nebulised or in dust form), nebulised pharmacologically active solutions (e.g., histamine, methacholine), or control solutions, followed by assessment of respiratory function. These tests are used in the diagnosis of asthma. (12 Dec 1998) |

| nasal provocation tests | Application of allergens to the nasal mucosa. Interpretation includes observation of nasal symptoms, rhinoscopy, and rhinomanometry. Nasal provocaton tests are used in the diagnosis of nasal hypersensitivity, including hay fever. (12 Dec 1998) |

| bronchial asthma | A condition of the lungs in which there is widespread narrowing of airways, varying over short periods of time either spontaneously or as a result of treatment, due in varying degrees to contraction (spasm) of smooth muscle, oedema of the mucosa, and mucus in the lumen of the bronchi and bronchioles; these changes are caused by the local release of spasmogens and vasoactive substances (e.g., histamine, or certain leukotrienes or prostaglandins) in the course of an allergic process. (05 Mar 2000) |
| bronchial atresia | Severe focal narrowing or obliteration of a segmental or lobar bronchus, usually associated with distal air trapping. (05 Mar 2000) |
| bronchial breathing | Breath sounds of a harsh or blowing quality, heard on auscultation of the chest, made by air moving in the large bronchi and barely, if at all, modified by the intervening lung; duration of the expiratory sound is as long as or longer than that of the inspiratory sound, and its pitch as high as or higher than that of the inspiratory sound; may be heard over a consolidated lung, above a pleural effusion due to an underlying compressed lung, and rarely over a pulmonary cavity; whispered pectoriloquy is another manifestation that usually can be elicited when bronchial breathing is present.
