| Research Abstract |
The effects of oral appliance on hypoxemia during sleep under hypoxic condition, at the summit of Mt.Fuji, was analyzed from SpO2, pulse rate and respiratory pattern. As results, SpO2 increased from 68％ to about 4％,and pulse rate decreased about 5bpm by application of oral appliance. These results indicate that oral appliance could improve hypoxemia during sleep to some extent. On the other hand, the indexes of ODI, AHI and respiratory patterns (obstructive, central, mixed type) were observed to decrease, but not statistically significant. At the high altitude, central apnea occurs which modify the result.
