ABSTRACT

The purpose of this study was to investigate the change of working memory for several special occupation group such as airline pilots’ and rescuer team who exposure to high altitude with 3,600m for several days and the improvement of cognitive function by diffusion type of oxygen supply during sleepiness. Twenty male volunteers aged between 25 and 35 were recruited. The first group of 10 participants were measured their spatial attention reaction time both in high and low perceptual load task after 1 hour entering the 3,600m altitude plateau and the same time of the second day, the third day and the fourth day. The second group of 10 participants was randomly divided into the oxygen group with diffusion types of oxygen supply during sleep and the exposure group, and the same tasks as the first group were measured in the above 4 time point. The results showed that the reaction time, accuracy and sensitivity of working memory was significantly declined when participant entering into the plateau (P<0.001). With the adaptation to the plateau environment in the short term, the speed can be alleviated to some extent, but there were no significant improve in accuracy and sensitivity. Moreover, the study also found that the use of oxygen during sleep through diffuse oxygen supply has a certain improvement effect on the recovery of verbal working memory speed, accuracy and sensitivity of spatial working memory under high altitude environment.
