摘要
目的 :探讨在 3 70 0m高原建立富氧室对机体运动后血气及心率的影响 ;方法 :对海拔 3 70 0m高原的 1 0例健康青年在进入富氧室前、后分别进行功率自行车递增负荷运动 ,检测pH值、二氧化碳分压 (PCO2 )、氧分压 (PO2 )、肺泡、动脉氧分压 (AaDO2 )、血氧饱和度 (SaO2 )、心率及 5min恢复心率 ;结果 :富氧后较富氧前pH增高显著 (P <0 .0 5) ;PCO2 、PO2 、SaO2 增高 ,即刻心率、AaDO2 降低 ,差别有非常显著性 (P <0 .0 1 ) ;恢复心率无统计学差异 (P >0 .0 5) ;结论 :富氧室能改善高原低氧人体气体交换和心脏工作效能 。
To study the effects of oxygen-enriched room on the blood gas and heart rate at 3 700m altitude. Method: The efficiency-bicycle exercise was performed in 10 healthy youths before and after entrance the oxygen-enriched room. The level of pH, PCO 2,PO 2,AaDO 2,SaO 2 and HR were measured using a AVL OPTICCA type blood analyzer. Results: The level of pH was increased (P<0.05) and the PCO 2, PO 2, SaO 2 were increased significantly (P<0.01) after the subjects had exercised in oxygen-enriched room for 12hr. But the HR, AaDO 2were decreased. Conclusion: The change of blood gas and heart function could be improved by oxygen-enriched room.
