| 摘 要： | 目的：探讨在3700m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3700m高原的10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＜0．05）；PCO2、PO2、SaO2增高，即刻心率、AaDO2降低，差别有非常显著性（P＜0．01）；恢复心率无统计学差异（P＞0．05）；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，是一种较为理想的高原供氧途径。

| Abstract: | 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. |
