Outline of Final Research Achievements |
This aim is to develop a new cooperation-free simple measuring device as a substitute for spirometer.We have developed a new device to monitor the change in tidal expiratory flow by applying variable negative pressure at the mouth during tidal expiration.The tidal expiratory flow increased by increasing the negative pressure during tidal expiration. The reduction in increment of the tidal expiratory flow occurred in obstructive ventilatory impairment. The change in increment of the tidal expiratory flow by variable negative expiratory pressure was shown to be useful for detecting ventilatory impairments. This result suggests that this new cooperation-free simple measuring developed device, is a substitute for spirometer.
