摘要
应用ＫＮＹ型咽鼓管通气功能检测仪检测１１０名现役飞行人员的咽鼓管开放压值（ＥＴＯＰＶ）及其波形（ＷＳ），并进行飞行试验（８０名）和低压舱试验（３０名），研究ＥＴＯＰＶ的大小及其ＷＳ与耳气压机能（ＯＢＦ）的关系。实验结果提示：（１）ＥＴＯＰＶ及其ＷＳ与ＯＢＦ之间有密切关系，ＥＴＯＰＶ大的人耳气压调节机能差，容易发生耳气压伤（ＥＢＴ），ＥＴＯＰＶ小的人耳气压调节机能好，很少发生ＥＢＴ。（２）Ｂ型波是咽鼓管通畅程度不良的波形，较Ａ型波更易发生ＥＢＴ。
KNY type eustachian tube ventilation function examination instrument was used to examine eustachium open pressure value and wave shape of the aviators (110 cases) on the active service, and for fly experiment (80 cases) and the altitude chamber test (30 cases) to investigate the relationship of the eustachium open pressure value's size and wave shape to the otic barofunction. The results suggest followings (l) There is close relation in the eustachium open pressure value and wave shape to the otic barofunction. The persons of large eustachian tube open pressure value tend to otic hypobarofunction, and are liable to otic barotrauma. The persons of small eustachium open pressure value have good otic barofunction,and rarely get otic barotrauma. (2) B type waves are the ones of the eustchian tube hypoventilation, pexsons with which liable to otic barotrauma.
