| pulmonary embolism | <cardiology> The lodgment of a blood clot in the lumen of a pulmonary artery, causing a severe dysfunction in respiratory function. Pulmonary emboli often have origin in the veins of the lower extremities where clots form in the deep leg veins and then travel to the lungs via the venous circulation. Symptoms and features include acute onset of shortness of breath, chest pain (worse with breathing) and rapid heart rate and respiratory rate. Some individuals may have haemoptysis. Diagnosis can be made on a ventilation perfusion scan of the lung or on a pulmonary angiogram. (15 Dec 1997) |

| 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 atresia |
congenital severe narrowing or obstruction of the opening between the pulmonary artery and the right ventricle, characterized by cardiomegaly, reduced pulmonary vascularity, and right ventricular atrophy. It is usually associated with tetralogy of Fallot, transposition of the great vessels, or other cardiovascular anomalies.

| pulmonary infarction |
localized necrosis of lung tissue caused by obstruction of the arterial blood supply, most often due to pulmonary embolism. Clinical manifestations range from the subclinical to pleuritic chest pain, dyspnea, hemoptysis, and tachycardia.

| pulmonary sequestration |
loss of connection of lung tissue, and sometimes bronchi, with the bronchial tree and with the pulmonary veins, the tissue receiving its arterial supply from the systemic circulation. The mass may be completely separated anatomically and physiologically from normally connected lung (extralobar pulmonary s.) or be in anatomical contiguity with and partly surrounded by normal lung (intralobar pulmonary s.). Called also accessory lung and bronchopulmonary s.
