| work of breathing | Respiratory muscle contraction during inspiration. The work is accomplished in three phases: that required to expand the lungs against its elastic forces (lung compliance work), that required to overcome the viscosity of the lung and chest wall structures (tissue resistance work), and that required to overcome airway resistance during the movement of air into the lungs (airway resistance work). Work of breaking does not refer to expiration, which is entirely a passive process caused by elastic recoil of the lung and chest cage.

| continuous positive pressure breathing | Artificial ventilation in which all inspirations are provided by positive pressure applied to the airway. Synonym: continuous positive pressure breathing, continuous positive pressure ventilation, intermittent positive pressure breathing, intermittent positive pressure ventilation. (05 Mar 2000) |
| positive-negative pressure breathing | Inflation of the lungs with positive pressure and deflation with negative pressure by an automatic ventilator. (05 Mar 2000) |
| pursed lips breathing | A technique in which air is inhaled slowly through the nose and mouth and exhaled slowly through pursed lips; used by patients with chronic obstructive pulmonary disease to improve their breathing by increasing resistance to air flow, forcibly dilating small bronchi. (05 Mar 2000) |
| shallow breathing | A type of breathing with abnormally low tidal volume. (05 Mar 2000) |
| stertorous breathing | Harsh, noisy breathing usually heard in an comatous patient. Synonym: stertorous breathing. (05 Mar 2000) |
| intermittent positive-pressure breathing | Application of positive pressure to the inspiratory phase of spontaneous respiration. See: controlled mechanical ventilation (12 Dec 1998) |
| kussmaul breathing | Air hunger. (12 Dec 1998) |
| angle of mouth | <anatomy> The lateral limit of the oral fissure. See: labial commissure. Synonym: angulus oris. (05 Mar 2000) |
| burning mouth syndrome | <syndrome> A group of painful oral symptoms associated with a burning or similar sensation. There is usually a significant organic component with a degree of functional overlay; it is not limited to the psychophysiologic group of disorders. (12 Dec 1998) |
| carp mouth | A mouth like that of the carp, with downturning of the corners; observed in Cornelia de Lange syndrome and Silver-Russel dwarfism. (05 Mar 2000) |
| parrot mouth | A condition of the horse in which the upper jaw is relatively longer than the lower, resulting in elongation of the upper incisors. (05 Mar 2000) |
| vestibule of mouth | That part of the mouth bounded anteriorly and laterally by the lips and the cheeks, posteriorly and medially by the teeth and/or gums, and above and below by the reflections of the mucosa from the lips and cheeks to the gums. Synonym: vestibulum oris, buccal cavity, vestibule of mouth. (05 Mar 2000) |
| glands of mouth | Glands that empty into the oral cavity. Synonym: glandulae oris. (05 Mar 2000) |
| roof of mouth | 1. <anatomy> The roof of the mouth. The fixed portion, or palate proper, supported by the maxillary and palatine bones, is called the hard palate to distinguish it from the membranous and muscular curtain which separates the cavity of the mouth from the pharynx and is called the soft palate, or velum. 2. Relish; taste; liking; a sense originating in the mistaken notion that the palate is the organ of taste. "Hard task! to hit the palate of such guests." (Pope) 3. Mental relish; intellectual taste. 4. <botany> A projection in the throat of such flowers as the snapdragon. Origin: L. Palatum: cf. F. Palais, Of. Also palat.
