目的：研究高压氧（ＨＢＯ）与一氧化氮（ＮＯ）对高原脱适应青年血流动力学的影响。方法：将海拔５０００ｍ以上居住１年返回海拔１４００ｍ的３６名青年随机分为：对照组；ＨＢＯ治疗组；ＮＯ治疗组。治疗前后分别用ＸＧⅢ型血液循环功能自动测试仪检测血流动力学。结果：对照组前后差别不显著（Ｐ＞０．０５）；ＨＢＯ组ＢＶ增加显著（Ｐ＜０．０５），Ｐ、ＳＶ增加非常显著（Ｐ＜０．０１），η降低非常显著（Ｐ＜０．０１）；ＮＯ组Ｐ、ＢＶ、ＳＶ、ｍＡＰ增加非常显著（Ｐ＜０．０１），ＡＬＴ、ＰＡＷＰ降低显著（Ｐ＜０．０５），ＴＰＲ、η降低非常显著（Ｐ＜０．０１）。结论：ＨＢＯ与ＮＯ对久居特高海拔返回后脱适应青年低排高阻性血流动力学有明显的增排降阻作用，吸入ＮＯ较ＨＢＯ效果更好
AIM: To investigate the effects of hyperbaric oxygen (HBO) and nitric oxide (NO) on hemodynamics in young off-center patients. Methods: Thirty-six youths who returned to an altitude of 1400m at an altitude of 5000m or above for 1 year were randomly divided into control group, HBO treatment group and NO treatment group. Before and after treatment were used XG type blood circulation automatic test instrument to detect hemodynamics. Results: There was no significant difference in the control group before and after treatment (P> 0.05). BV increased significantly in HBO group (P <0.05), P and SV increased significantly (P <0.01) 0.01). The levels of P, BV, SV and mAP in NO group were significantly increased (P <0.01), ALT and PAWP decreased significantly (P <0.05) ). CONCLUSION: HBO and NO have a significant antihypertensive effect on the low-row, high-resistance hemodynamics of detached youth after resuming the UH elevation, and inhaled NO is better than HBO
