本文对326名脱尘矿工和69名不接触尘毒的健康工人分别进行了肺通气功能测定，并对影响脱尘矿工肺通气功能损害的因素进行了分析，结果表明：无论是肺通气功能的实测值、实测值占预计值的百分比，还是肺通气功能的异常率，或是最大呼气流速容量曲线的比较分析，均显示脱尘矿工的肺通气功能损害较对照工人为严重。多因素分析结果表明：接尘起始年代、慢性支气管炎对脱尘工人肺通气功能损害的影响尤为明显。即接尘起始年代越早或有慢性支气管炎者肺通气功能损害越重。
In this paper, 326 dust miner and 69 health workers exposed to dust poisoning were tested for pulmonary ventilation, and the factors influencing lung function impairment of dust miner were analyzed. The results showed that both lung ventilation function The measured value, the measured value as a percentage of the predicted value, the abnormal rate of pulmonary ventilation function, or the comparative analysis of the maximal expiratory flow rate capacity curve all showed that the lung ventilator damage of the dust miner was more serious than the control workers. The results of multivariate analysis showed that chronic bronchitis had a significant effect on the impairment of lung ventilation in workers exposed to dust at the beginning of dust collection. Namely the earliest or the beginning of the dust or chronic bronchitis, pulmonary function impairment, the more severe.
