| Outline of Final Research Achievements |
In this study, to discover the weakness region in the airway, the airway configuration change under the negative pressure loading was observed.Subject was 33 year-old, female, who had no OSA. She agreed with the purpose of this study, and signed. The mask and the syringe were connected, and the pressure gage was set on the syringe.The device was pushed to her face, and covered her nose and mouth. She received the direction of her maximal inspiration, and the negative pressure within the syringe was measured as Max.NP.The airway was scanned via a CBCT (GALILEOS, Sirona, USA, NY) with 15 seconds, under following conditions; normal breathing and under S_NP. The configuration and volume of the airway were evaluated via image analysis software.At the maximal inspiration, the negative pressure within the syringe was 7.8 kPa. S_NP was 5.0 kPa (65% Max.NP).The airway configuration at normal breathing was elliptical shape. On the other hand, the airway under S_NP presented triangle shape.
