RESUMO

Miller, G. J., Hearn, C. E. D., and Edwards, R. H. T. (1971).Brit. J. industr. Med.,28, 152-158. Pulmonary function at rest and during exercise following bagassosis. Lung function and exercise responses were investigated in two groups of Indian bagasse workers to assess whether there were any permanent sequelae following regular exposure to bagasse dust in a group of 12 men who had developed bagassosis and a group of six who had not. Ventilatory capacity, lung volumes, single breath carbon monoxide transfer factor (TF), diffusion capacity of the alveolar-capillary membrane (Dm), and volume of blood in the pulmonary capillaries (Vc) were measured, and then exercise responses were investigated with a cycle ergometer. The ventilatory response to hypercapnia was assessed by a modified re-breathing method.
