Knowledge about the safety of travel to high or moderate altitude during pregnancy or with small children is limited. Previous recommendations restricting travel during pregnancy to an altitude of 2133 m a.s.l. may be too cautious; however, not enough research has been done to allow any recommendation based on scientific evidence. Infants and children generally do well at moderate altitude (< 3000 m a.s.l.), if ascent is gradual and if the child is watched closely for any developing signs or symptoms of acute mountain sickness or high-altitude pulmonary edema. Infants of residents of low altitude may develop right-heart failure due to excessive pulmonary artery hypertension when exposed to altitudes more than 3500 m a.s.l. over several months (subacute mountain sickness).
关于孕期或携带幼儿前往高海拔或中等海拔地区旅行的安全性，目前所知有限。此前将孕期旅行限制在海拔2133米以下的建议可能过于谨慎；然而，目前尚未进行足够的研究以基于科学证据给出任何建议。如果海拔上升缓慢，并且密切观察儿童是否出现急性高山病或高原肺水肿的任何迹象或症状，婴儿和儿童一般在中等海拔（<3000米）情况下表现良好。低海拔地区居民的婴儿如果在数月内暴露于海拔超过3500米的地区（亚急性高山病），可能会因肺动脉高压过高而出现右心衰竭。
