Abstract

Objective: Obstructive sleep apnea (OSA) exhibits high prevalence, yet limited polysomnography (PSG) resources highlight an urgent need for large scale screening. This study assessed the diagnostic efficacy of a combined reflective photoplethysmography and ultra-wideband radar device (Zhao-Guan wireless monitoring system, ZG-Sys) compared to PSG. The aims were to establish ZG-Sys OSA severity cutoff values and define its clinical implementation prospects.

Methods: This prospective, open-label diagnostic study was conducted in a sleep center, collecting 433 valid datasets for suspected sleep disorders from June 2023 to April 2024, via synchronous Type 1 PSG and ZG-Sys monitoring. ZG-Sys consists of a ring-style pulse oximeter (Circul) and an IR-UWB radar device (OrbSense). Statistical analysis utilized Spearman rank correlation, Bland-Altman analysis, and Receiver Operating Characteristic (ROC) curves to evaluate agreement and determine optimal ZG-AHI cutoff values against PSG-AHI standards (5, 15, and 30 events/h).

Results: ZG-AHI showed a significant correlation with PSG-AHI (Spearman r = 0.800, ICC = 0.908, P < 0.001). The optimal ZG-AHI cutoff for detecting moderate-to-severe OSA (PSG-AHI ≥15) was 20.8 events/h, yielding a high area under the curve (AUC) of 0.943. ZG-Sys demonstrated high sensitivity (89.10-90.80%) and specificity (85.30-88.80%) for identifying moderate-to-severe OSA. Although consistency was good across multiple sleep disorders (eg, parasomnias), weaker correlations were observed in the continuous positive airway pressure (CPAP) treatment group.

Conclusion: ZG-Sys demonstrated moderate consistency with PSG across multiple sleep disorders, proving significant clinical value for screening and diagnosing moderate to severe OSA. Featuring simple charging, reusability, and real-time monitoring capabilities, ZG-Sys shows potential for clinical screening in sleep center settings.

联合反射光容积脉搏波和超宽带雷达设备诊断阻塞性睡眠呼吸暂停的性能：与多导睡眠图的比较。

目的：阻塞性睡眠呼吸暂停（OSA）患病率高，但有限的多导睡眠图（PSG）资源突出了大规模筛查的迫切需要。本研究评估了联合反射光容积脉搏波和超宽带雷达设备（兆管无线监测系统，ZG-Sys）与PSG的诊断效果。目的是建立ZG-Sys OSA严重程度临界值并确定其临床应用前景。方法：本前瞻性、开放标签诊断研究在睡眠中心进行，通过同步1型PSG和ZG-Sys监测，于2023年6月至2024年4月收集433例疑似睡眠障碍的有效数据集。ZG-Sys由环形脉搏血氧仪（circle）和红外-超宽带雷达设备（OrbSense）组成。统计分析利用Spearman秩相关、Bland-Altman分析和受试者工作特征（ROC）曲线来评估一致性，并根据PSG-AHI标准（5、15和30事件/小时）确定最佳ZG-AHI截止值。结果：ZG-AHI与PSG-AHI有显著相关性（Spearman r = 0.800, ICC = 0.908, P < 0.001）。检测中重度OSA （PSG-AHI≥15）的最佳ZG-AHI截止值为20.8个事件/h，曲线下面积（AUC）为0.943。ZG-Sys对中重度OSA具有较高的敏感性（89.10-90.80%）和特异性（85.30-88.80%）。尽管多种睡眠障碍（如睡眠异常）的一致性很好，但在持续气道正压（CPAP）治疗组中观察到的相关性较弱。结论：ZG-Sys对多种睡眠障碍的PSG具有中等一致性，对筛查和诊断中重度OSA具有重要的临床价值。ZG-Sys具有简单的充电、可重复使用和实时监测功能，显示了在睡眠中心设置的临床筛查的潜力。

期刊介绍： Nature and Science of Sleep is an international, peer-reviewed, open access journal covering all aspects of sleep science and sleep medicine, including the neurophysiology and functions of sleep, the genetics of sleep, sleep and society, biological rhythms, dreaming, sleep disorders and therapy, and strategies to optimize healthy sleep. Specific topics covered in the journal include: The functions of sleep in humans and other animals Physiological and neurophysiological changes with sleep The genetics of sleep and sleep differences The neurotransmitters, receptors and pathways involved in controlling both sleep and wakefulness Behavioral and pharmacological interventions aimed at improving sleep, and improving wakefulness Sleep changes with development and with age Sleep and reproduction (e.g., changes across the menstrual cycle, with pregnancy and menopause) The science and nature of dreams Sleep disorders Impact of sleep and sleep disorders on health, daytime function and quality of life Sleep problems secondary to clinical disorders Interaction of society with sleep (e.g., consequences of shift work, occupational health, public health) The microbiome and sleep Chronotherapy Impact of circadian rhythms on sleep, physiology, cognition and health Mechanisms controlling circadian rhythms, centrally and peripherally Impact of circadian rhythm disruptions (including night shift work, jet lag and social jet lag) on sleep, physiology, cognition and health Behavioral and pharmacological interventions aimed at reducing adverse effects of circadian-related sleep disruption Assessment of technologies and biomarkers for measuring sleep and/or circadian rhythms Epigenetic markers of sleep or circadian disruption.
