AIRWAY CONSTRICTION

我们研究了吸气流速与呼吸道的关系。 清醒的坐位和仰卧位被诊断为梗阻的受试者的开放 睡眠呼吸暂停(OSA)。使用了两种主要的测量技术；测量 鼻腔呼吸时鼻部的流量和压力，以及 声学脉冲技术(咽喉学)在嘴呼吸时应用。 8名阻塞性睡眠呼吸暂停综合征和8名对照受试者在GCRC进行了筛查，包括 体重指数和体脂百分比测定(卡尺)。吸入 然后进行测量。分析表明， 阻塞性睡眠呼吸暂停综合征患者与对照组咽部顺应性的差异。 在大学公园校区启动的工作正在#年继续进行 与好时医疗中心的肺危重护理合作。

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.
