AIRWAY CONSTRICTION

我们研究了吸气流速与气道的关系 诊断为阻塞的清醒坐位和仰卧位受试者的开口 睡眠呼吸暂停（OSA）。使用了两种主要的测量技术：测量 在鼻呼吸过程中鼻子的流量和压力，以及 声脉冲技术（咽测量法）应用于口呼吸。 在GCRC筛选了8名OSA和8名对照受试者，包括 BMI和体脂百分比测定（卡尺）。吸入 然后进行测量。分析显示， OSA和对照组咽部顺应性的差异。 在大学公园校园开始的工作仍在继续， 与好时医疗中心的肺重症监护合作。

We have studied the relation between inspiratory flow rate and airway opening in awake seated and supine subjects with diagnosed Obstructed Sleep Apnea (OSA). Two primary measurement techniques were used; measure of flows and pressures at the nose during nasal breathing, and an acoustic pulse-technique (pharyngometry) applied during mouth breathing. Eight OSA and eight control subjects were screened at the GCRC including BMI and percent body fat determination (calipers). Inhalation measurements were then performed. Analyses demonstrated a substantial difference in the pharyngeal compliance of OSA and control subjects. Work initiated at the University Park Campus is continuing in cooperation with Pulmonary Critical Care at the Hershey Medical Center.
