Non-Contact Point of Care Device for Sleep Studies

项目摘要/摘要 提出了一种简便、便携的非接触式诊断阻塞性睡眠呼吸暂停(OSA)的方法 临床或家庭环境中使用的技术。意义：据估计，美国有1800万人在睡觉 呼吸暂停和最近的流行病学研究表明，这种疾病的患病率正在上升。OSA是 与包括抑郁症和2型糖尿病在内的几种负面健康后果有关。目前， 多导睡眠图(PSG)是诊断阻塞性睡眠呼吸暂停综合征的金标准检查。PSG系统很复杂。他们 通常需要熟练的技术人员进行设置和持续监控，以确保结果的准确性 从而将它们的使用限制在睡眠诊所。然而，最近对睡眠诊所使用情况的审查发现， OSA的诊断服务并不总是能够满足需求。家庭睡眠呼吸暂停测试(HSAT)系统确实存在， 然而，像目前的PSG系统一样，它们使用的传感模式受到错误校准或 当用户在夜间活动时，效率会降低。HSAT系统通常使用的传感器(戴鼻子 插管、脑电、体积描记皮带等)必须与患者直接接触，并连接到中央 病人必须佩戴的记录器。患者报告说，佩戴/连接的传感器不舒服，在一些 病例会影响他们的睡眠质量。这些问题阻碍了许多人有效诊断阻塞性睡眠呼吸暂停 人口包括未参保/保险不足的人、农村人口、有无障碍需求的个人、有无障碍者 发展性残疾和儿童。假设：假设一种易于使用的非接触式 能够感知睡眠呼吸暂停严重程度(AHI)标准测量的系统将可用于诊断 一些人口没有得到当前PSG和HSAT技术的充分服务，从而提高了 那些受OSA影响的人。具体目标：在第一阶段的工作中，拟议的传感技术是 证明是非常有效的。在第二阶段，提出了以下目标：1)成熟的 将硬件原型化为生产就绪系统，2)最终确定处理软件并开发以下接口 最终用户/临床医生，以及3)在人体内对照当前最先进的系统验证系统性能 课题研究。

Project Summary/Abstract Proposed is an easy-to-use, portable method for diagnosis of obstructive sleep apnea (OSA) using non-contact technology for use in clinical or home setting. Significance: An estimated 18 million Americans have sleep apnea and recent epidemiological studies indicate the prevalence of this disorder is on the rise. OSA is associated with several negative health outcomes including depression and type 2 diabetes. Currently, polysomnography (PSG) is the gold standard test for diagnosis of OSA. PSG systems are complex. They typically require a skilled technician for setup and continuous monitoring to ensure the accuracy of results thereby limiting their use to sleep clinics. However, recent reviews of access to sleep clinics have found supply of OSA diagnostic services not always able to meet demand. Home sleep apnea test (HSAT) systems do exist, however, like current PSG systems, they employ sensing modalities that suffer from issues of miscalibration or diminished efficacy as the user moves through the night. Sensors typically used by HSAT systems (nose worn cannula, EEG, plethysmography belts, etc.) must be in direct contact with the patient and are wired to a central recorder that the patient must wear. Patients report that worn/wired sensors are uncomfortable and in some cases affect their sleep quality. These issues present a barrier to effective diagnosis of OSA for many populations including the un/under-insured, rural populations, individuals with accessibility needs, those with developmental disabilities, and children. Hypothesis: It is hypothesized that an easy-to-use non-contact system capable of sensing standard measures of sleep apnea severity (AHI) will make available diagnosis to several populations underserved by current PSG and HSAT technology thereby increasing quality of life for those individuals effected by OSA. Specific Aims: In the Phase I effort the proposed sensing technology was demonstrated to be exceptionally effective. In Phase II the following aims are proposed: 1) Mature the prototype hardware into a production ready system, 2) Finalize processing software and develop interfaces for end users / clinicians, and 3) Validate system performance against current state-of-the-art system in a human subject study.
