摘要 对425例尘肺病人和285例煤矿工人的肺通气功能(VC、FVC、FEV_1、FEV_1/FVC%)和肺弥散量(DLco)进行了测定和研究,以206例健康不接尘工人肺功能测定数据为样本,提出尘肺患者肺功能损害程度的分级标准:正常范围:VC、FVC、Dlco>80%,FEV_1>75%,FEV_1/FVC>70%;轻度损害:VC、FVC、DLco65~79%,FEV_160~74%,FEV_1/FVC 55~69%;中度损害:VC、FVC、DLco50~64%,FEV_140~59%,FEV_1/FVC35~54%;重度损害:VC、FVC、DLco<50%,FEV_1<40%,FEV_1/FVC<35%。用此标准检验425例尘肺病人,结果较符合我国的实际情况。 Ventilatory functions(VC,FVC,FEV_1,FEV_1/FVC%)and singlebreath diffusing capacity(DLco)of 425 pneumoconiosis patients and 285coal miners were examined and studied,and compared with those of 206healty workers without dust exposure.Classification of the degree ofrespiratory impairment was proposed as follows:normal range:VC,FVC,DLco>80% of predicted,FEV_1>75% of predicted,FEV_1/FVC>70%;slight impairment:VC,FVC,DLco 65-79% of predicted,FEV_1 60-74% of predicted,FEV_1/FVC 55-69%;moderateimpairment:VC,FVC,DLco 50-64% of predicted,FEV_1 40-59% ofpredicted,FEV_1/FVC 35-54%;heavy impairment:VC,FVC,DLco<50% of predicted,FEV_1<40% of predicted,FEV_1/FVC<35%Pulmonary functions of the 425 patients assessed according to the proposedcriteria showed that these were proper and suitable for pneumoconiosis in ourcountry.
