Switzerland (827 mountaineers ascending to 4559 m) examined the effects of susceptibility, pre-exposure, and ascent rate on acute mountain sickness.5 In this study, preexposure was defined as having spent more than 4 days above 3000 m in the preceding 2months, and slow ascent was defined as ascending

在瑞士就827名登上4559米高度的登山运动员进行了一项调查，检测了易感性，预暴露，以及上升速率对急性高空病的影响[5]。

We found no systematic review or RCTs evaluating the effect on different rates of ascent or acclimatisation in preventing acute mountain sickness.

我们没有发现有关评估不同上升速率或适应在预防急性高空病的效果的系统综述或随机对照试验。

Slow ascent* We found no systematic review or RCTs evaluating the effect on different rates of ascent or acclimatisation in preventing acute mountain sickness.

缓慢上升*我们没有发现有关评估不同上升速率或适应在预防急性高空病的效果的系统综述或随机对照试验。
