【摘要】 目的：探讨能更准确、客观地进行职业病肺功能损伤分级的途径。方法：采用国家鉴定标准中规定的六项指标（即ＦＶＣ、ＦＥＶ１、ＦＥＶ１％、ＭＶＶ、ＲＶ％和ＤＬｃｏ）测定２４７例Ⅰ期尘肺病人（矽肺７４例、石棉肺７３例、煤工尘肺１００例）的肺功能，对以单项指标和三项组合性指标的分级鉴定结果作了对比研究。结果：①采用六项指标中任一项为标准，２４７例总肺功能损伤率为９３．３％，其中石棉肺９７．３％，矽肺和煤工尘肺分别为９１．９％，８９．０％；②采用三项指标组合，按ＦＶＣ、ＦＥＶ１、ＲＶ％组和ＦＶＣ、ＦＥＶ１、ＤＬｃｏ组鉴定分级，两组总肺功能损伤率分别为７０．８％、７３．３％。结论：以三项指标组合进行鉴定分级更符合我国国情。更多还原

【Abstract】 Objective: In order to classify exactly impairment of respiratory function. Methods: They were tested including FVC、FEV1、FEV1%、MVV、RV% and DLco in male grade Ⅰpneumoconiosis (74 silicosis, 73 asbestosis, 100 coal workers’ pneumoconiosis). Results: single index was used for classifying impairments of lung function, the total rate impaired of 247 patients was 93.3. If three indices were combined( such as FVC、FEV1 and DLco) as classifying criteria, the total rate impaired was 70.8￣73.3%. Conclusion: We suggested that three indices combined were commended as basis for classifying impairment of lung function. The reasons introduced were discussed.更多还原
