| 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) |
| vesicular | 1. Composed of or relating to small, saclike bodies. 2. Pertaining to or made up of vesicles on the skin. Origin: L. Vesicula = a little bladder (18 Nov 1997) |
| vesicular appendage | A small fluid-filled cyst attached by a slender stalk to the fimbriated end of the uterine tube; a vestigial remnant of the embryonic mesonephric duct. Synonym: appendix vesiculosa, Morgagni's hydatid, morgagnian cyst, stalked hydatid, vesicular appendage. (05 Mar 2000) |
| vesicular appendices of uterine tube | A small fluid-filled cyst attached by a slender stalk to the fimbriated end of the uterine tube; a vestigial remnant of the embryonic mesonephric duct.

| vesicular exanthema | An extinct disease of swine caused by vesicular exanthema virus of swine, a member of the family Caliciviridae; it closely resembled foot-and-mouth disease and, in swine, was characterised by fever, loss of weight, and vesicles on the snout, tongue, and feet. (05 Mar 2000) |
| vesicular exanthema of swine | A calicivirus infection of swine characterised by hydropic degeneration of the oral and cutaneous epithelia. (12 Dec 1998) |
| vesicular exanthema of swine virus | The type species of the genus calicivirus, an RNA virus infecting pigs. The resulting infection is an acute febrile disease which is clinically indistinguishable from foot and mouth disease. Transmission is by contaminated food. (12 Dec 1998) |
| vesicular keratitis | Keratitis with coalescence of areas of epithelial corneal oedema. (05 Mar 2000) |
| vesicular keratopathy | Corneal epithelial oedema with formation of vacuoles. (05 Mar 2000) |
| vesicular mole | <gynaecology, oncology, tumour> A relatively rare mass or tumour that can form within the uterus at the beginning of a pregnancy. The cause of hydatidiform mole is unknown. Symptoms include vaginal bleeding, uterine growth, nausea and vomiting. Some hydatidiform moles may become malignant (cancerous) where they are referred to as a choriocarcinoma. Incidence: 1 in 1,500 births. (02 Jan 1998) |
