目的 :探讨富氧室对高原移居者睡眠前后血氧饱和度 (SaO2 )的影响。方法 :在海拔370 0m建立富氧室 ,12名移居高原 30天的健康青年入室休息和睡眠 10h ,观察受试者睡眠前后SaO2 的变化及出室后 4h内SaO2 的改变 ,并与常氧组比较。结果 :富氧组入室 1h后SaO2 明显升高 [(90 .17± 3.38) % ,(94± 2 .17) % ,P <0 .0 1],第二日晨起安静时SaO2 较睡眠前增高 2 .33% ,差别有非常显著性 (P <0 .0 1) ,受试者出室后 1h、2h、3h的SaO2 依次为 (95 .5± 1.0 0 ) % ,(93.83±1.6 4) % ,(93± 2 .17) % ,与常氧组比较差别均有显著性。结论 :在高原建立富氧室可明显改善移居者睡眠前后的SaO2 ,提高睡眠质量。
Objective: To investigate the effect of oxygen-enriched chamber on oxygen saturation (SaO2) before and after sleep in plateau settlers. Methods: The healthy young people who had oxygen enrichment room and 12 migrants who had migrated to plateau for 30 days were housed at rest and sleeping for 10 hours at an altitude of 370 0 m. The changes of SaO2 before and after sleep and the changes of SaO2 within 4 hours after leaving the room were observed. Compare Results: In the oxygen-enriched group, SaO2 was significantly increased after 1 h of admission (90.17 ± 3.38% vs 94 ± 2.17%, P <0.01) (95% ± 1.0%), (93.83 ± 1.6%) in the order of 1h, 2h and 3h, respectively )%, (93 ± 2.17)%, respectively, with the difference between normoxia group were significant. Conclusion: The establishment of oxygen-enriched room in the plateau can significantly improve SaO2 before and after sleep, and improve sleep quality.
