Abstract

Purpose: This study aimed to evaluate the accuracy of a Bluetooth position monitor called NaTu sensor and its mobile phone application for detecting sleep position among patients with obstructive sleep apnea (OSA) during polysomnography (PSG).

Methods: A cross-sectional study was conducted on adults with suspected of having OSA who underwent PSG. Sleep positions were recorded simultaneously using a video-validated PSG position sensor and the NaTu sensor. The area under the Receiver Operator Characteristic curve (ROC AUC), sensitivity, and specificity values were calculated to evaluate the validity of the NaTu sensor.

Results: Ninety participants (56.7% male) were included, with median age of 40.0 years and body mass index of 29.4 kg/m². The mean AHI was 58.4 ± 31.2 events/hour, categorizing the severity of OSA as mild (5.6%), moderate (18.9%), and severe (75.5%). Sleep positions (supine, lateral right, lateral left) identified by the NaTu sensor closely agreed with the video-validated PSG. The kappa statistic demonstrated almost perfect agreement (k = 0.95, P < 0.001) for overall position recording. The ROC AUC for identifying supine, lateral right, and lateral left positions ranged from 0.974 to 0.981, with sensitivity ranging from 95.1% to 99.1% and specificity from 96.5% to 99.6%.

Conclusion: Our wearable sensor monitoring significantly agrees with video-validated PSG in identifying sleep positions. This device is reliable and accurate for position monitoring and could be an alternative tool for monitoring positions in in-lab PSG, home sleep apnea testing, or tracking positional treatment at home.

在阻塞性睡眠呼吸暂停患者中比较 NaTu 传感器和视频验证多导睡眠监测仪的睡眠体位监测。

目的：本研究旨在评估一种名为NaTu传感器的蓝牙体位监测器及其手机应用程序在多导睡眠图（PSG）中检测阻塞性睡眠呼吸暂停（OSA）患者睡眠体位的准确性：对疑似患有 OSA 并接受 PSG 检查的成人进行了横断面研究。使用经过视频验证的 PSG 位置传感器和 NaTu 传感器同时记录睡眠位置。通过计算接收者特征曲线下面积（ROC AUC）、灵敏度和特异性值来评估 NaTu 传感器的有效性：共纳入 90 名参与者（56.7% 为男性），中位年龄为 40.0 岁，体重指数为 29.4 kg/m2。平均 AHI 为 58.4 ± 31.2 次/小时，OSA 严重程度分为轻度（5.6%）、中度（18.9%）和重度（75.5%）。NaTu 传感器确定的睡眠姿势（仰卧、右侧卧、左侧卧）与视频验证的 PSG 非常吻合。卡帕统计显示两者几乎完全吻合（k = 0.95，P 结论：我们的可穿戴传感器监测与视频验证的 PSG 非常吻合：在识别睡眠体位方面，我们的可穿戴传感器监测与经视频验证的 PSG 非常一致。该设备在体位监测方面可靠而准确，可作为实验室 PSG、家庭睡眠呼吸暂停测试或家庭体位治疗跟踪中的体位监测替代工具：注册：Thaiclinicaltrials.org，编号为 TCTR20210701008。

期刊介绍： The journal Sleep and Breathing aims to reflect the state of the art in the international science and practice of sleep medicine. The journal is based on the recognition that management of sleep disorders requires a multi-disciplinary approach and diverse perspectives. The initial focus of Sleep and Breathing is on timely and original studies that collect, intervene, or otherwise inform all clinicians and scientists in medicine, dentistry and oral surgery, otolaryngology, and epidemiology on the management of the upper airway during sleep. Furthermore, Sleep and Breathing endeavors to bring readers cutting edge information about all evolving aspects of common sleep disorders or disruptions, such as insomnia and shift work. The journal includes not only patient studies, but also studies that emphasize the principles of physiology and pathophysiology or illustrate potentially novel approaches to diagnosis and treatment. In addition, the journal features articles that describe patient-oriented and cost-benefit health outcomes research. Thus, with peer review by an international Editorial Board and prompt English-language publication, Sleep and Breathing provides rapid dissemination of clinical and clinically related scientific information. But it also does more: it is dedicated to making the most important developments in sleep disordered breathing easily accessible to clinicians who are treating sleep apnea by presenting well-chosen, well-written, and highly organized information that is useful for patient care.
