| 摘 要： | 根据 X 线胸片表现,选择间质型和结节型Ⅰ期煤工尘肺83例,分别测定了第一秒时间肺活量(FEV_(1·0)),用力肺活量(FVC)、最大呼气中期流速(MMEF)和最大通气量(MVV)四项肺功能指标。发现间质型尘肺肺功能的均值低于结节型,尤其以 FEV_(1·0)和 MMEF 降低明显,可以提示:间质型尘肺患者的肺功能损害较结节型严重,并且损害部位主要在小气道。这个结果有助于预测Ⅰ期煤工尘肺的代偿机能和正确进行劳动能力鉴定,并说明:尘肺肺功能的改变不但与尘肺的期别有关,而且与尘肺的病型有关。

| Abstract: | According to the chest X-ray findings the author selected 83 cases with simple degree I CWP of nodular and interstitial pneumoconioses and measured their forced expiratory volume(FEV_(1.0)),forced viral capacity(FVC),maximum middle expiratory flow(MMEF)and max- imum ventilation volume(MVV)respecttively.The results show that the mean value of pulmonary function in the interstitial pneumoconioses is lower than that in the nodular ones.Especially,FEV and MMEF declined significantly.It is suggested that the lung capacity lesion of the interstitial pneumoconioses is more severe than that of the nodular ones and the location of lesion is mainly in the small airway.This re- sult can help us to predict the compensatory function and to evaluate precisely the work capacity of degree I CWP.It is showed that pulmo- nary functionl change is not only related to the degree of pneumoco- niosis,but also to the type of it. |
