3A1-E04 Basic research towards development of an expiration gas analysis system(Medical Robotics and Mechatronics (1))

In the purpose of pathological state by exhalation, we have developed an expiration gas analysis system. Also now there are various problems when subjects use the equipment for collecting breath gas. So we have developed the new equipment for collecting breath gas that using a pressure sensor to improve the ability to collect the sample. And because we want to know the difference between breathing resistance of the new equipment for collecting breath gas and currently equipment for collecting breath gas. So we have a subject to use the equipment of both. And we examined the breathing resistance at that time.
