Abstract
A generally healthy office working population (N = 644) was investigated using eight pulmonary function indices obtained from maximum expiratory flow volume curves and single breath nitrogen/closing volume tests. Abnormal test results were related to smoking history. Results showed a) increases in pulmonary dysfunction among current smokers on most tests, b) delta nitrogen as the test most sensitive to smoking effects, and c) some reversal of smoking-related dysfunction in exsmokers. These findings may have implications in the early detection of chronic obstructive lung disease.
