摘要
目的 :探讨在高原建立富氧室对移居者肺通气功能的影响 ;方法 :对移居海拔3 70 0m一年的 1 0名受试者在进入富氧室前后分别进行功率自行车递增负荷运动 ,用ES80 0肺功量仪检测肺通气功能 ,并与安静时比较 ;结果 :与安静时对照 ,富氧前运动后FEV1 /FVC %降低 ,MVV增加 ,均有非常显著性差异 (P <0 .0 1 ) ,FVC、FEF2 5 %～ 75 % 、FEV1 、PEF都有降低趋势 ,但无统计学意义 (P >0 .0 5) ;富氧次日运动后FVC、FEV1 、PEF和MVV增加非常显著 (P <0 .0 1 ) ;与富氧前运动后比较 ,富氧次日运动后FVC、FEF2 5 %～ 75 % 、FEV1 、PEF、FEV1 /FVC %及MVV均显著增加 (P <0 .0 5或P <0 .0 1 ) ;结论 :富氧室能改善高原移居者运动后的肺通气功能 ,是一种较为理想的供氧途径。
Objecitve:To study the effects of oxygen-enrichment room on pulmonary ventilation in migrants at high altituede.Method:10 subjects,migtanted to altitude of 3 700m for 1yr,were enroled in this study.The bicycle-loaded exercise was performed after and before entrance to oxygen-enrichment room and compared with rest condition.And the level of FEV,MVV,PEF,FVC etc,were examined using ES 800-pulmonary function device.Result:The level of FEV 1/FVC% was decreased.The level of MVV was increased(P<0.01) after entrance the room.The level of FVC,FEV 1,PEF and MVV were significantly increased (P<0.01) in next day after entrance oxygen-room.Conclusion:The pulmonary function could be improved by oxygen-enrichment-room after exercise in migrants exposed to high altitude.
