石棉工人运动试验前后SaO_2变化的研究

THE CHENGES OF SaO 2 BEFORE AND AFTER THE EXERCISE TESTING.

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。

Objective:To study the relationship between exercise and SaO 2 of asbestos workers.Methods:30 asbestos workers and 10 control workers were exercise tested and examined SaO 2.Results:Comparing with the control,SaO 2 of asbestos workers dicreased obviously after the exercise testing( P< 0 05),among the groups of asbestos workers,the chenges of SaO 2 after the exercise testing of A0、AⅠ、AⅡ groups were 1 5%,2 6%,9 8%,that correlated negetively with FVC% and DL co %.Conclusions:Absorption tolerance of oxygen and exersise tolerance of asbestos workers are reduced.
