摘　　要：为探讨人体低氧条件下循环功能的代偿水平，进行了有关测试。结果显示：高海拔区在总体适应水平上每搏量减少（P＜0．01），心输出量及平均动脉压增加（P＜0．01），且随高度增加，后两项均需增加（P＜0．05）。对于不同群体来说，适应良好者每搏量及总外周阻力不变，心输出量增加（P＜0．01）；适应不良者每搏量减少（P＜0．05），总外周阻力增加，心输出量亦增加但显著性稍差（P＜0．05）。推测人体在不同低氧条件下具有不同的心血管适应能力，且该适应能力具有个体差异。To observe the compensatory abilities in circulatory function of human body in hypoxic conditions, the authors did related work. It shows that in high sea level SI decreased (P ＜0. 01), CI and MAP increasd (P＜0.01) and both CI and MAP increasd(P＜0. 05) with higher altitude. For different groups, the good compensatory group had 0. 01), and the bad one had less SI (P＜0.05),more TRP, and also increased CI, but the significant difference was less than the former (P＜0. 05 ). The results suggest that human body has not only different abilities of circulatory function in different hypoxic conditions but also individual differences of the abilities.
