Chronic Bronchitis and Pulmonary Emphysema

Abstract

The impairment of respiratory function associated with chronic bronchitis and pulmonary emphysema is reviewed. Environmental factors play a role in pathogenesis of the condition. In diagnosis, the history is more helpful than are physical findings and radiologic changes. The most useful functional test is a measure of vital capacity together with an estimate of expiratory flow rate. Recommendations for management are made, stressing sympathetic understanding by the physician. Measures for treatment of episodes of acute pulmonary insufficiency also are discussed briefly.
