VEMs ana u^Cq at rest (steady state method) were determined. In some cases the residual volume was measured, the resistances of the airwaya (body plethysmography). of respiratory dead space, of arterio-al-veolar CUj gradient and also of D^gQ at work on a cydoergometer. The subjects wersubdivided into 5 groups on the basis of the chest X-ray pattern (U1CC das.tucation. Cincinnati): 1st group with X-ray pattern 0/0 or 0/1 and with asbestos exposure less than 10 years (average exposure 5.7 years): 2nd group with X-ray pattern 0/0 or 0/1 and with asbestos exposure longer than 10 years (average expc :. -e 21.2 years); 3rd group with X-rays 1/0 or 1/1; 4th group with X-rays 1/2, 2/1 or 2/2; 5th group with X-rays 2/3. 3/2 or 3/3.
