摘要
通过140例煤工尘肺(CWP)的通气功能和部分换气功能测定,综合分析和评价CWP呼吸功能损害的特点。CWP早期即有肺气肿及低氧血症的存在,小气道阻力增加及尘斑气肿是CWP的重要病理基础,低氧血症与肺气肿有密切关系,DLco降低Ⅲ期最明显与间质纤维化程度增高有关。
This paper analysed and evaluated the characteristics of lung function impairment in coal workers' pneumoconiosis(CWP)
by measuring ventilation and exchange function in 140 cases of CWP.There were pulmonary emphysema and hypoxemia in the
early stage of CWP.Increase of small air way resistance and the presence of focal emphysema were chiefly pathological base for
CWP.Hypoxemia was closely related with emphysema.DLCO was decreased obviously in stage Ⅲ and was related to multipli-
cation of interstitial fibrosis.
