DESCRIPTION (provided by applicant): Snoring, a symptom of increased upper airway resistance during sleep, is extremely common in children. Such obstructive sleep disordered breathing (OSDB) is now recognized as having substantial neurocognitive, neurobehavioral, and cardiovascular consequences. One of the major limitations in diagnosing OSDB is the need for relatively complex, burdensome, and costly procedures, such as laboratory polysomnography. Barron Associates, Inc. (BAI) and the University of Virginia (UVA) propose to develop the SoundTrak data acquisition and analysis system, a low-cost sleep monitor for use in individuals' home environments to non invasively and economically acquire and analyze data pertaining to OSDB. The Phase I SoundTrak system will unobtrusively collect both low- and high-frequency sound data via a bed headboard-mounted microphone and a PC bedside data logger. Recent work by UVA physicians demonstrated that high-frequency inspiratory sounds are a marker for the occurrence of OSDB in children. Thoracic breathing movements of monitored subjects will be measured using BAI's patent-pending wireless thoracic band technology, enabling discrimination of the monitored subject's sleep sounds from other sources. The prototype SoundTrak system will be validated based on an overnight laboratory polysomnogram and a multi-night home sleep study, the latter of which is expected to provide more representative data for diagnosing OSDB.

描述（由申请人提供）：打鼾是睡眠期间上呼吸道阻力增加的症状，在儿童中极为常见。这种阻塞性睡眠呼吸障碍（OSDB）现在被认为具有显著的神经认知、神经行为和心血管后果。诊断OSDB的主要限制之一是需要相对复杂、繁琐和昂贵的程序，如实验室多导睡眠图。巴伦联合公司(BAI)和弗吉尼亚大学（UVA）提出开发SoundTrak数据采集和分析系统，这是一种用于个人家庭环境的低成本睡眠监测器，以非侵入性和经济地采集和分析与OSDB有关的数据。第一阶段SoundTrak系统将通过床头板安装的麦克风和PC床边数据记录器悄悄地收集低频和高频声音数据。UVA医生最近的工作表明，高频吸气音是儿童OSDB发生的标志。受监测对象的胸部呼吸运动将使用BAI正在申请专利的无线胸带技术进行测量，从而能够区分受监测对象的睡眠声音与其他来源。SoundTrak原型系统将基于一个通宵的实验室多导睡眠图和一个多夜的家庭睡眠研究进行验证，后者预计将为诊断OSDB提供更具代表性的数据。
