To explore the blood oxygen saturation and heart rate changes of the Antarctic explorers.
During August 2010 to April 2011, the changes in blood oxygen saturation, heart rate and plateau reaction of 16 Antarctic expedition team in different plateau environments (Tibetan plateau versus Antarctic plateau) were monitored with the noninvasive pulse oximeter MD300-C. The extent of acute mountain sickness was determined according to the Lake Louise Consensus acute mountain reaction symptom scores and judgment method.
The changes of blood oxygen saturation, heart rate at different altitudes of 110, 3650, 4300 m (96.8% ± 1.2%,89.1% ± 1.2%, 86.1% ± 2.0%, (75.0 ± 5.4) times/min, (104.0 ± 4.3) times/min, (113.0 ± 5.2) times/min,F = 214.155, 240.088,both P < 0.05). With rising latitude and elevation gradient in Antarctic plateau, the changes of blood oxygen saturation, heart rate at different altitudes of 2000, 2500, 3000, 3500 and 4087 m(91.9% ± 1.3%,90.5% ± 1.3%,87.6% ± 1.4%,85.0% ± 1.8%,81.5% ± 2.2%, (85.9 ± 3.2) times/min, (90.6 ± 2.8) times/min, (97.8 ± 4.1) times/min, (102.0 ± 3.4) times/min, (106.3 ± 3.9) times/min, F = 105.418, 90.174, both P < 0.05). Levels of blood oxygen saturation and heart rate were both correlated with the risk of altitude sickness (r = -0.446 and 0.565, both P < 0.05).
As the increases of altitude, there are significant changes in oxygen saturation, heart rate of the Antarctic explorers. And with the increases of altitude, the risk of altitude sickness gradually increases.
探讨南极探险队员的血氧饱和度及心率变化。
2010年8月至2011年4月期间，使用无创脉搏血氧仪MD300-C对16支南极考察队在不同高原环境（青藏高原与南极高原）下的血氧饱和度、心率及高原反应变化进行监测。根据路易斯湖共识急性高原反应症状评分及判断方法确定急性高原病的程度。
在海拔110、3650、4300米处血氧饱和度、心率的变化（分别为96.8%±1.2%、89.1%±1.2%、86.1%±2.0%，(75.0±5.4)次/分钟、(104.0±4.3)次/分钟、(113.0±5.2)次/分钟，F = 214.155、240.088，P均<0.05）。在南极高原，随着纬度和海拔梯度升高，在海拔2000、2500、3000、3500和4087米处血氧饱和度、心率的变化（分别为91.9%±1.3%、90.5%±1.3%、87.6%±1.4%、85.0%±1.8%、81.5%±2.2%，(85.9±3.2)次/分钟、(90.6±2.8)次/分钟、(97.8±4.1)次/分钟、(102.0±3.4)次/分钟、(106.3±3.9)次/分钟，F = 105.418、90.174，P均<0.05）。血氧饱和度水平和心率均与高原病风险相关（r = -0.446和0.565，P均<0.05）。
随着海拔升高，南极探险队员的血氧饱和度、心率有显著变化。且随着海拔升高，高原病风险逐渐增加。
