对592名接触矽尘、石棉尘、煤(矽)尘的工人和425名尘肺病人以及206名健康不接尘工人的肺功能进行了测定,建立了肺通气功能和换气功能预计值回归公式。比较研究了接触不同粉尘的工人和尘肺病人的肺功能损害程度及其特点,表明尘肺病人各项肺功能指标明显低于接尘工人;矽肺病人中混合性肺功能损害者较多,石棉肺病人限制性损害较明显,而煤工尘肺病人则多表现为阻塞性的功能损害。
The lung function of 592 workers exposed to silica dust, asbestos dust, coal (silicon) dust, 425 pneumoconiosis patients and 206 healthy workers without dust was measured and the regression formula of the predicted value of pulmonary ventilation function and ventilation function was established . The lung function damage and its characteristics of workers exposed to different dusts and pneumoconiosis patients were comparatively studied. The results showed that the lung function indexes of pneumoconiosis patients were significantly lower than those of dust-pick workers. Among the silicosis patients, there were more mixed pulmonary dysfunction patients, asbestosis patients Restrictive damage is more obvious, and coal workers pneumoconiosis patients are more manifestations of obstructive impairment.
