Abstract

In order to study relationships between acute mountain sickness (AMS) observations done both during a short-term hypoxic exposure in a hypobaric chamber, and in field conditions during a high altitude expedition, nine subjects were submitted to a 9-h hypoxic exposure in a hypobaric chamber. Then, they experienced a high altitude expedition in the Himalayas. The Lake Louise AMS scoring system was used to assess AMS in both conditions, especially the self report questionnaire. During the expedition, the mean self report score of each subject, defined as the ratio between the sum of daily self report scores and the duration of the expedition, appears to be correlated not only to the maximal self report score observed in altitude (r = +0.77, p < 0.05) but also to the self report and self report+clinical assessment scores observed at the end of the hypobaric chamber sojourn (r = +0.81, p < 0.01 and r = +0.75, p < 0.05, respectively). In conclusion, the Lake Louise AMS scoring system, especially the self report questionnaire, is relevant to assess AMS with simplicity and rapidity both in laboratory and in field conditions. Our study also suggests that AMS induced by a short term sojourn in a hypobaric chamber is related to AMS observed in field conditions.
