为了探讨石棉工人运动与血氧水平的关系，作者对一批石棉作业工人（简称石棉工人）和对照组进行了运动试验前后ＳａＯ２（动脉血氧饱和度）的监测。结果显示，与对照组相比，石棉工人组运动后ＳａＯ２出现明显下降（Ｐ＜０．０５）；石棉工人组内比较，ＡⅡ组运动后的ＳａＯ２平均下降了９．８％，ＡⅠ组运动后ＳａＯ２平均下降了２．６％，Ａ０组运动后ＳａＯ２平均下降１．５％。运动前后ＳａＯ２的下降值与ＦＶＣ、ＦＥＶ１、ＭＶＶ、ＤＬＣＯ等肺功能指标呈负相关。提示石棉工人运动时摄氧能力减退、血氧水平降低，导致运动能力下降。
In order to explore the relationship between asbestos workers’ movement and blood oxygen level, the authors monitored the SaO2 (arterial oxygen saturation) before and after the exercise test on a group of asbestos workers (asbestos workers) and control group. The results showed that compared with the control group, SaO2 in asbestos workers decreased significantly after exercise (P <0.05); in the asbestos workers group, SaO2 decreased by 9.8% SaO2 decreased by 2.6% on average, while SaO2 in A0 group decreased by 1.5% on average. The decrease of SaO2 before and after exercise was negatively correlated with pulmonary function indexes such as FVC, FEV1, MVV and DLCO. Prompted asbestos workers during exercise reduced oxygen capacity, blood oxygen levels decreased, resulting in decreased exercise capacity.
