In this paper we review some effects of acute and short-term exposure to altitude on maternal and fetal cardio-pulmonary function. These effects may be seen during commercial aircraft flight or mountain ascent in cablecars. In addition cardio-pulmonary changes during maternal exercise at altitude are discussed. Altitudes up to 2 500 m are well tolerated by mother and fetus in uncomplicated pregnancies. Slight maternal exercise does not provoke fetal heart rate changes. However, in pregnancies at risk, for example because of maternal smoking, precaution with exposure to altitude is justified. Particularly at risk may be stewardesses if they continue their strenuous work while pregnant. Living at high altitude (more than 2 500 m) the lower oxygen partial pressure has some well known negative effects on mother and fetus. The importance of the various mechanisms of acclimatisation and adaptation to hypoxaemia, and other factors influencing reproduction when living at high altitude are reviewed and discussed.
在本文中，我们回顾了急性和短期暴露于高原环境对母婴心肺功能的一些影响。这些影响可能出现在商业飞机飞行或乘坐缆车登山过程中。此外，还讨论了孕妇在高原地区运动时的心肺变化。在无并发症的妊娠中，海拔高达2500米时母亲和胎儿耐受性良好。轻微的母体运动不会引起胎儿心率变化。然而，对于有风险的妊娠，例如由于母亲吸烟，谨慎对待高原暴露是合理的。如果空乘人员在怀孕期间继续从事高强度工作，她们可能特别危险。生活在高海拔地区（超过2500米），较低的氧分压对母亲和胎儿有一些众所周知的负面影响。本文回顾并讨论了各种适应低氧血症的机制以及其他影响高海拔地区生殖的因素的重要性。
