[目的] 研究石棉工人心肺代偿能力。[方法] 对照组和三组石棉工人(AO,AI,AII)进行运动心肺功能试验。[结果] 与对照组相比,石棉工人之Wm ax,VO2m ax,VO2m ax/kg 均明显降低(P< 0.05),VO2m ax 与DI呈负相关,与BR呈正相关;石棉工人组间比较:AII组之Wm ax,VO2m ax,VO2m ax/kg 小于A1 组,A1组小于AO组,经t检验及F检验,其组间差异有显著意义(P< 0.05);[结论] 提示石棉粉尘严重影响作业工人运动能力,运动试验更能科学地反映石棉肺患者劳动或运动时的心肺代偿功能
[Objective] To study the cardiorespiratory capacity of asbestos workers. [Methods] The control group and three groups of asbestos workers (AO, AI, AII) for exercise cardiopulmonary function test. [Results] The Wm ax, VO2m ax and VO2m ax / kg of asbestos workers were significantly lower than those of the control group (P <0.05). VO2m ax was negatively correlated with DI and positively correlated with BR. The Wm ax, VO2m ax and VO2m ax / kg in AII group were less than those in A1 group and A1 group was less than that in AO group. There was significant difference between the two groups (P <0.05) by t-test and F-test. [Conclusion] Affect the ability of workers to exercise, exercise test can more scientifically reflect asbestos lung labor or exercise cardiopulmonary decompensation
