Studies on countermeasure for exercise-induced arterial hypoxemia

我们调查了年轻女性吸入高氧和/或高二氧化碳气体是否会改善运动性动脉低氧血症(EIAH)。受试者使用自行车测功器进行了两次独立的运动测试，30s全力性自行车和三轮10s自行车，间隔120s。在两种运动中，吸入30%O2或20%O2+5%CO2均可减轻常氧下观察到的EIAH，但未发现30%O2和5%CO2对EIAH的相加作用。

We investigated whether exercise-induced arterial hypoxemia (EIAH) would be improved by inhalation of hyperoxic and/or hypercapnicgas in young women. Subjects performed two separate exercise tests, 30s all-out cycling and three bouts of 10s cycling with 120s intervals, using a cycle ergometer. In both exercises, inhaled 30%O2or 20%O2+5%CO2attenuated EIAH that observed in normoxia, but additive effects of 30%O2and 5%CO2gases on EIAH were not found.
