We wanted to test the hypothesis that gender differences in effects of smoking on the rate of decline in pulmonary function may be related to gender differences in the frequency of smoking. Data from the Vlagtwedde-Vlaardingen study in The Netherlands were analysed, to investigate the rate of decline in forced expiratory volume in one second (delta FEV1) in relation to smoking status and gender...

متن کاملShort term variability in FEV1 and bronchodilator responsiveness in patients with obstructive ventilatory defects.
Short term variability in FEV1 and responsiveness to inhaled bronchodilator were measured in 150 patients with obstructive ventilatory defects. The range of initial FEV1 was 0.5-4.71 and the natural variability over a 20 minute period when expressed in absolute terms was similar over the entire range, and differed insignificantly from that found in normal subjects. The increase in FEV1 and vita...

متن کاملHow to interpret reduced FEV1/VC ratio with normal FEV1
Whether the combination of low FEV1/VC ratio with normal FEV1 represents a physiological variant or a sign of early airflow obstruction is unknown. We studied 40 subjects presenting with low FEV1/VC but FEV1 within the range of normality predicted by ERS reference equations and 10 healthy controls. All subjects completed two questionnaires and underwent comprehensive pulmonary function testing ...
