Research Abstract	It showed a tendency that blood flow and blood speed were more increased in the state of warmed than that ofcooled. Also it was showed a tendency that maximum middle ear total pressure value associated with the gas exchange via middle ear mucosa was higher in the state of warmed than that of cooled. It seems that the increase of maximum middle ear total pressure value was associated with the increase of the diffusion of CO2and the decrease of the absorption of O2 via middle ear mucosa.
