DESCRIPTION (Adapted from applicant's abstract): Respiratory effort monitoring is a crucial aspect of Nocturnal polysomnography (NPSG) testing. This is usually carried out by strain gage belts which measure chest or abdominal wall expansion. This approach is recognized to be less accurate and less sensitive than intrathoracic pressure measurements monitored from within the esophagus (Pes - Pressure within the esophagus). Most consider current methods of Pes monitoring too cumbersome and impractical for routine NPSG testing. Our proposal is to develop a small electronically based catheter for practical routine Pes monitoring in patients undergoing NPSG testing. This catheter utilizes new MEMS (Micro Electro Mechanical Systems) pressure transducers allowing for an approximate 1 mm diameter size, minimizing patient discomfort. This catheter satisfies a recognized need of enhanced sensitivity and specificity of respiratory monitoring during the testing process and could clearly become the standard method of measuring respiratory effort during Nocturnal polysomnography (NPSG) studies. Additionally, with multiple transducers, it can provide insight into the anatomic region(s) of obstruction within the upper airway and thus assist in the surgical management of patients suffering from obstructive sleep apnea. Recent advances in transducer technologies and methods packaging have paved the way for the development of our Micro Esophageal Respiratory Catheter (MERC).

描述（根据申请人的摘要改编）：呼吸努力 监测是夜间多摄影学（NPSG）的关键方面 测试。这通常是由应变量规带进行的 胸部或腹壁膨胀。 这种方法被认为是 与胸前压力相比，准确较少，敏感 从食道内监测的测量（PES-压力 食道）。 大多数也考虑当前的PES监视方法 对于常规NPSG测试而繁琐且不切实际。 我们的建议是 开发一个基于电子的小导管，以实用常规 接受NPSG测试的患者的PES监测。 这个导管 利用新的MEMS（微电机械系统）压力 传感器允许大约1毫米的直径尺寸，最小化 病人不适。 该导管满足公认的需求 增强的灵敏度和呼吸监测期间的特异性 测试过程，显然可以成为 测量夜间多摄影（NPSG）期间的呼吸努力 研究。此外，对于多个传感器，它可以提供洞察力 进入上呼吸道内的阻塞的解剖区域 因此，协助患有患者的手术管理 阻塞性睡眠呼吸暂停。传感器技术的最新进展和 方法包装为我们的微观开发铺平了道路 食管呼吸道导管（MERC）。 拟议的商业应用：不可用。
