Sixty-seven patients referred to a sleep laboratory with a tentative diagnosis of obstructive sleep apnea were examined with a device designed for home use as an apnea screening system. Direct comparison was made between data obtained by the portable device and by data acquired simultaneously with standard polysomnographic techniques. The portable recorder measured nasal/oral airflow, chest wall movement, cardiac rhythm, and blood oxygen saturation. There was no significant difference in the number of disordered breathing events (apneas and hypopneas) recorded by the two systems. The portable device was found to have a sensitivity of 95% and a specificity of 96%. Indications and limitations for use of the portable home apnea screening test are reviewed and guidelines for normalcy suggested.
67名被转诊至睡眠实验室、初步诊断为阻塞性睡眠呼吸暂停的患者，使用一种设计用于家庭的设备作为呼吸暂停筛查系统进行了检查。对便携式设备获取的数据与通过标准多导睡眠图技术同时采集的数据进行了直接比较。便携式记录仪测量鼻/口腔气流、胸壁运动、心律和血氧饱和度。两个系统记录的呼吸紊乱事件（呼吸暂停和呼吸不足）数量没有显著差异。发现便携式设备的灵敏度为95%，特异性为96%。本文回顾了便携式家庭呼吸暂停筛查测试的适应证和局限性，并提出了正常标准的指导原则。
