目的:探讨富氧室在高原军事医学中的应用价值。方法:在海拔3700m高原室内充氧,使氧浓度提高到24.0%～25.0%。10名受试者在富氧室睡眠12h,检测富氧前,富氧2h、11h及富氧后2h静息状态下和运动中的脉搏氧饱和度(SaO2)和心率。结果:入富氧室2h和11hSaO2增高,心率降低(P<0.01)。脱离富氧后2h,SaO2已接近富氧前水平。富氧后踏车运动中平均SaO2较富氧前增高,平均心率降低(P>0.05)。结论:富氧环境下12h对改善高原缺氧和机体能量储备有一定作用。
Objective: To explore the application value of oxygen-enriched chamber in military medicine in the plateau. Methods: In the altitude of 3700m plateau indoor oxygenation, the oxygen concentration increased to 24.0% ~ 25.0%. Ten subjects were allowed to sleep in oxygen-enriched room for 12 hours. The oxygen saturation (SaO2) and heart rate during rest before and after oxygen enrichment (2h, 11h and 2h after oxygen enrichment) were measured. Results: After 2h and 11h, the oxygenation rate increased and the heart rate decreased (P <0.01). After 2h from oxygen enrichment, SaO2 is close to the pre-oxygen level. After oxygen enrichment treadmill exercise SaO2 average oxygen enrichment before the increase, the average heart rate decreased (P> 0.05). Conclusion: 12h oxygen enrichment environment to improve the plateau hypoxia and body energy reserves have a certain effect.
