研究富氧室改善高原缺氧及力竭运动后血液流变学的变化。海拔 370 0m ,向室内注氧 ,将氧浓度提高到 2 4 0 %～ 2 5 0 %。10名青年在富氧室休息和睡眠 12h,检测未富氧静息状态、未富氧力竭运动后、富氧及力竭运动后的血液流变学。未富氧力竭运动后红细胞压积 (HCT)和血液粘度 (ηb)、还原粘度 (ηr)、血细胞聚集系数 (VAI)较未富氧静息状态增高 ,差异有非常显著性意义或差异有显著性意义 (P <0 0 1或P <0 0 5 ) ,富氧及力竭运动后各项指标较未富氧静息状态差异无显著性意义 (P >0 0 5 ) ,较未富氧力竭运动后ηb、ηr、血浆粘度 (ηp)降低 ,差异有显著性意义 (P <0 0 5 )。高原富氧 12h可明显改善因缺氧及力竭运动所引起的血液粘度的变化
Oxygen-enriched chamber was used to study the changes of hemorrheology after hypoxia and exhaustive exercise on the plateau. Elevation 370 0m, to the indoor oxygen, the oxygen concentration increased to 240 ~ 250%. Ten young people were resting and sleeping for 12 hours in the oxygen-enriched room, and the hemorheology after oxygen-enrichment and exhaustive exercise was tested after the oxygen-free exhaustive exercise was tested. HCT, ηb, ηr, and VAI were significantly higher than those without oxygen-enriched resting status after exhaustive exhaustive exercise, with significant differences or significant differences Significant significance (P <0.01 or P <0 05), oxygen enrichment and exhausted exercise than the non-oxygen-enriched resting state no significant difference (P> 0 05), more than the rich After exhaustive exercise, ηb, ηr and plasma viscosity (ηp) decreased, the difference was significant (P <0 05). Oxygen enrichment for 12 h at plateau significantly ameliorated the changes of blood viscosity caused by hypoxia and exhaustive exercise
