The high prevalence of obstructive sleep apnea (OSA) in the general population makes diagnosing OSA a high priority. Typically, patients receive in-person instructions to hook up the home sleep apnea test devices. Using recorded video instructions would save health care personnel time and improve access to OSA diagnostics for patients in remote areas. The aim of this study was to compare the quality of home sleep apnea test recordings when using in-person and video hookup instructions in a randomized study.
A total of 100 patients aged 18 to 70 years with suspected OSA were randomized to receive either in-person or video hookup instructions for the Nox T3 device (Nox Medical, Reykjavik, Iceland). The overall quality of the resulting sleep studies was analyzed by determining the number of technically invalid studies. The recording quality of 4 sensors (pulse oximeter, nasal cannula, thorax and abdominal respiratory inductance plethysmography belts) was assessed by checking for signal artifacts.
No significant difference was found between the 2 groups in any quality index. Only 1 (2%) and 2 (3.9%) sleep studies were technically invalid in the in-person and video instructions group, respectively. The average ± standard deviation recording quality of the 4 sensors combined was 94.8% ± 13.6% for the in-person and 96.0% ± 11.0% for the video instructions group.
This study found no difference in home sleep apnea test recording quality between the 2 groups. Video hookup instructions are therefore viable and an important step toward a telemedicine-based way of diagnosing OSA.

阻塞性睡眠呼吸暂停（OSA）在普通人群中的高患病率使得诊断 OSA 成为当务之急。通常，患者会接受亲自指导以连接家庭睡眠呼吸暂停测试设备。使用录制的视频说明可以节省医疗保健人员的时间，并为偏远地区的患者提供更好的 OSA 诊断途径。本研究的目的是在一项随机研究中比较使用亲自和视频连接说明时家庭睡眠呼吸暂停测试记录的质量。
共 100 名年龄在 18 至 70 岁之间、疑似 OSA 的患者被随机分为亲自或视频连接说明组，用于 Nox T3 设备（Nox Medical，雷克雅未克，冰岛）。通过确定技术无效研究的数量来分析整个睡眠研究的质量。通过检查信号伪影来评估 4 个传感器（脉搏血氧仪、鼻插管、胸部和腹部呼吸感应体描记带）的记录质量。
在任何质量指标上，两组之间均无显著差异。在亲自和视频说明组中，仅有 1 项（2%）和 2 项（3.9%）睡眠研究技术上无效。4 个传感器（脉搏血氧仪、鼻插管、胸部和腹部呼吸感应体描记带）的平均记录质量分别为亲自组的 94.8%±13.6%和视频说明组的 96.0%±11.0%。
本研究未发现两组家庭睡眠呼吸暂停测试记录质量存在差异。因此，视频连接说明是可行的，是实现基于远程医疗的 OSA 诊断方法的重要一步。
