尘肺诊断和分期依赖于X线诊断。但进行尘肺病人代偿机能的评定却有赖于肺功能的测定。了解煤工尘肺病人的肺功能损害程度,为代偿机能的评定、动态观察提供机能方面的依据,我们对我市62例煤工尘肺病人进行了肺功能测定,并与非接尘工人(对照组)、接尘工人和不够Ⅰ期尘肺者进行了对比分析。结果如下: Pneumoconiosis diagnosis and staging depend on X-ray diagnosis. However, the evaluation of patients with pneumoconiosis compensatory function depends on the determination of lung function. To understand the degree of pulmonary function impairment of coal workers with pneumoconiosis, to evaluate the compensatory function and to provide the basis for dynamic observation, we measured the pulmonary function of 62 coal workers with pneumoconiosis in our city and compared them with non-exposed workers Group), dust workers and those with stage I pneumoconiosis were compared. The result is as follows:
