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。
Objective: To explore a more accurate and objective pathological classification of occupational lung function damage. Methods: A total of 247 patients with Stage I pneumoconiosis (74 silicosis, 73 asbestosis, 100 pneumoconiosis of coal workers) were enrolled in this study according to the six indicators (FVC, FEV1, FEV1%, MVV, RV% and DLco) ) Of pulmonary function, to single indicators and three combination of indicators of the classification results were compared. Results: ①All of the six indicators were used as criteria. The total lung injury rate was 93.3% in 247 cases, including 97.3% in asbestosis, 91.9% in silicosis and coal worker’s pneumoconiosis, 89.0% %. ②Three indexes were used to identify and classify FVC, FEV1, RV% and FVC, FEV1 and DLco groups, the total lung injury rate was 70.8% and 73.3% respectively. Conclusion: The combination of three indicators to identify grading more in line with China’s national conditions.
