为了评价女工尘肺患者肺功能的损伤程度,需要正常标准作为对比,但正常值的大小与性别、年龄、身高、体重、劳动强度等因素有关,因而我们测定了健康女工的四项肺通气功能指标,并求得了四项指标的正常值和三项预计值公式,以作为健康女工常数指标的参考。 In order to evaluate the degree of impairment of lung function in female workers with pneumoconiosis, we need the normal standard as the contrast, but the normal size is related to gender, age, height, weight, labor intensity and other factors, so we measured the four female lung workers ventilation index , And obtained the normal value of the four indicators and the three expected value formula, as a healthy female workers constant index reference.
