| obstructive lung disease | <chest medicine> A form of lung disease that manifests as acute or chronic, narrowing or blockage of the smaller airways in the lungs, causing increased resistance to airflow in the bronchial tubes (for example asthma, silicosis, chronic obstructive pulmonary disease from smoking). (27 Sep 1997) |
|---|---|
| obstructive murmur | A murmur caused by narrowing of one of the valvular orifices. (05 Mar 2000) |
| obstructive pneumonia | Infection of lung resulting from obstruction of airway, by narrowing resulting from previous disease process, persistent bronchospasm, thick secretions or by aspiration of a foreign body. (05 Mar 2000) |
| obstructive pulmonary overinflation | Emphysema caused by obstruction of airways that has greater effect on expiration than inspiration; occurs reversibly with bronchospasm of asthma; localised process can be due to aspiration of a foreign body. (05 Mar 2000) |
| obstructive sleep apnoea | A form of sleep apnoea which occurs as the result of a physical occlusion of the oropharyngeal airway during sleep. (27 Sep 1997) |
| obstructive thrombus | A thrombus due to obstruction in the vessel from compression or other cause. (05 Mar 2000) |
| obstructive uropathy | <nephrology, urology> A sudden disorder which results in the complete blockage of urine flow out the bladder and/or urethra. Pressure rises in the urinary tract causing a backward pressure on the kidneys. Bilateral hydronephrosis (kidney enlargement), hypertension and damage to the kidneys (acute renal failure) will occur if the obstruction is not relieved. Causes include prostate disease, tumours and cystocele. Origin: Gr. Pathos = disease (27 Sep 1997) |
| lung diseases, obstructive | Any disorder marked by persistent obstruction of bronchial air flow. (12 Dec 1998) |
