在模拟狭窄和尸体喉研究中应用声鼻测量仪测量声门下区气管横切面积（CSA），比较真实CSA和喉气管模拟狭窄中声学测量的CSA，以证实声刺激反射在测量上呼吸道狭窄中的准确性。用Plexiglas管制成男性（大）和女性（小）喉，大者内径为19mm，CSA为2．83cm2；小者内径13mm，C...
Acoustic nasal gauges were used to measure tracheal cross-sectional area (CSA) of the subglottic in mock stenosis and cadaver laryngeal studies to compare the CSA of acoustically measured CSA in realistic CSA and laryngotracheal stenosis to demonstrate that acoustic stimuli reflexes are useful in measuring upper airway stenosis Accuracy Plexiglas tube with male (large) and female (small) throat, large diameter 19mm, CSA 2.83cm2; small diameter 13mm, C ...
