目的 :观察在海拔 370 0m建立富氧室对人体血流动力学的影响。方法 :10名受试者在进入富氧室前后分别用XG—Ⅲ型血液循环功能自动测试仪检测血流动力学。结果 :富氧室后较富氧室前P、TPR、ALT降低明显 (P <0 0 5 ) ,η、PAWP、CCP降低非常明显 (P <0 0 1) ;SV、mAP、BK增加明显 (P <0 0 5 ) ,BV增加非常明显 (P <0 0 1)。结论 :富氧室在海拔370 0m对人体血流动力学有明显的改善作用。
Objective: To observe the effect of oxygen enrichment chamber on hemodynamics in 370 0 m altitude. Methods: Ten subjects were tested for hemodynamics by XG-Ⅲ automatic blood circulation tester before and after entering the oxygen-enriched room. Results: The levels of P, TPR and ALT decreased significantly (P <0 05), and η, PAWP and CCP decreased significantly (P 0 01) P <0 0 5), BV increased significantly (P <0.01). Conclusion: Oxygen-enriched chamber can obviously improve the hemodynamics of the human body at an elevation of 370 0m.
