... significant effect on the ventilatory function. There was no significant difference in the lung function test values between the smokers and nonsmokers in both groups. The flow-volume curves were constructed for the unexposed and exposed groups of workers. At 25% FVC, in the group exposed to tobacco dust...

...B. Thiessen; O.F. Pedersen A total of 2,880 maximum expiratory flow-volume curves were performed in a controlled double-blind cross-over examination designed to evaluate the bronchodilating effects of two different nebulized doses of salbutamol (1.75 and 0.875 mg) and ipratropium bromide (0.175...

Clark We have studied 40 workers with varying industrial exposure to asbestos, using routine spirometry and maximal expiratory flow volume curves (MEFVC). Abnormalities of MEFVC were common and seen...

... between the two modes of treatment with regard to the bronchodilator response assessed by measurement of specific airway conductance, registration of expiratory flow-volume curves and determination of helium response. The results suggest that the use of an extension tube may not promote a more extensive...

...H. Wiesemann; H. von der Hard Flow-volume curves were measured in a group of 43 healthy children breathing air and a helium-oxygen gas mixture. Analysis of maximal flow at 25, 50 and 75% of forced vital capacity and at 50, 60 und 70% of total lung capacity (TLC) was performed...
