Outline of Final Research Achievements |
In order to develop a screening test to predict who is more likely to suffer from acute mountain sickness (AMS), we examined the cardio-respiratory responses to acute and gradual (1%/min) decrease in inspired oxygen content (12-13%) during middle intensity (35-40%max) exercise at sea level and compared these between the subjects who had suffered and not suffered from AMS at high altitude. We recruited two subjects’ group, one was the university students who had climbed the same high mountain (3000m) and the other was the middle-aged and elderly who have well experienced in high mountains above 2500m. The results suggested that we had better adopt the gradual hypoxic protocol based on subjects’ comfort and safety, and that people whose arterial oxygen saturation falls rapidly and below 75% during hypoxic exercise, or whose minute ventilation and end-tidal CO2 partial pressure at each stage show lower and higher value respectively should be susceptible to AMS at high altitude.
