title: [Lung ventilation parameters in various pneumoconiosis forms during follow-up in miners of Kouzbass].
abstract: Studies of spirometric parameters in 120 miners who live in Kemerovo region and suffer from diagnosed pneumoconiosis demonstrated disordered pulmonary ventilation in 53.3% of the examinees. The highest velocity parameters in spirometry are seen in nodular form, the lowest ones--in mixed form of pneumoconiosis. During 2 years of follow-up forced expiratory volume over the first second decreased. Velocity and volume spirometric parameters in pneumoconiosis among coal miners of Kemerovo region under 2 years of follow-up demonstrate invert correlation with initial age of the patients when pneumoconiosis was diagnosed.
