| 摘 要： | 研究青藏铁路车厢内供氧是否能减轻缺氧对列车员脑组织的损伤。采用自主开发的近红外组织氧无损监测仪检测了在低海拔(平均海拔0.5～2.0km)路段和车厢内供氧的高海拔(平均海拔3.0～5.0 km,车厢内氧浓度维持在23%～25%)路段的列车员脑组织氧饱和度(rSO2),同时用脉搏血氧仪无创检测列车员指端脉搏血氧饱和度(SpO2)。高海拔路段同低海拔路段相比,rSO2平均下降3.6%,SpO2平均下降3.7%。这表明:车厢内供氧缓解了高原缺氧,但因个别列车员脑组织rSO2仍显著下降,所以对青藏铁路列车员的脑保护仍待研究。

| Abstract: | High-altitude hypoxia is harmful to the attendants' health on the Qinghai-Tibet railway.A near infrared tissue oximeter was developed to non-invasively measure the cerebral regional oxygen saturation(rSO2) of attendants along the low-altitude section(altitude 0.5-2.0 km) and the high-altitude section(altitude 3.0-5.0 km) with enhanced oxygen level to 23%-25% in the compartments.The pulse oxygen saturation(SpO2) was detected simultaneously using a pulse oximeter.The cerebral rSO2 decreased by 3.6%,while the ... |
