|---|---|
| pulmonary emphysema | Condition of the lungs characterised by increase beyond normal in the size of air spaces distal to the terminal bronchioles, either from dilatation of the alveoli or from destruction of their walls. (12 Dec 1998) |
| pulmonary encephalopathy | Coma seen with advanced lung failure and resultant hypoventilation. Synonym: CO2 narcosis, hypoxic-hypercarbic encephalopathy, pulmonary encephalopathy. (05 Mar 2000) |
| pulmonary eosinophilia | A disease characterised by pulmonary infiltrations of eosinophils and blood eosinophilia. (12 Dec 1998) |
| pulmonary fibrosis | Chronic inflammation and progressive fibrosis of the pulmonary alveolar walls, with steadily progressive dyspnea, resulting finally in death from oxygen lack or right heart failure. (12 Dec 1998) |
| pulmonary fistula | A parietal fistula communicating with the lung. (05 Mar 2000) |
| pulmonary gas exchange | The exchange of oxygen and carbon dioxide between alveolar air and pulmonary capillary blood. (12 Dec 1998) |
| pulmonary glomangiosis | Glomangiosis occurring within small pulmonary arteries in severe pulmonary hypertension and congenital heart disease. (05 Mar 2000) |
| pulmonary glomus | A structure similar to the carotid body, found in relation to the pulmonary artery. Synonym: glomus pulmonale. (05 Mar 2000) |
| pulmonary haemosiderosis | Haemosiderosis usually associated with mitral stenosis and marked by an accumulation of macrophages loaded with haemosiderin within the alveoli. (05 Mar 2000) |
| pulmonary hamartoma | <tumour> Hamartoma of the lung, producing a coin lesion composed primarily of cartilage and bronchial epithelium. Synonym: adenochondroma. (05 Mar 2000) |
| pulmonary hypertension | <cardiology> Abnormally elevated blood pressure within the pulmonary circuit (pulmonary artery). Pulmonary hypertension may be secondary to another disease process (VSD, ASD, severe COAD) or occur as a primary disease process known as primary pulmonary hypertension. (27 Sep 1997) |
| pulmonary hypostasis | Hydrostatic congestion of the lung. (05 Mar 2000) |
| pulmonary incompetence | Defective closure of the pulmonic valve permitting regurgitation into the right ventricle during diastole. (05 Mar 2000) |
| pulmonary insufficiency | Pulmonary here refers to the valve between the right ventricle of the heart and the pulmonary artery. If this valve is insufficient (incompetant) in its performance, blood sloshes back from the pulmonary artery into the right ventricle. (12 Dec 1998) |
