Abstract

Purpose: Obstructive sleep apnea (OSA) is the most common sleep-disordered breathing. The high prevalence makes its diagnosis a priority. To perform type III sleep studies, patients usually receive instructions from a technician. The switch to instructions through a video could save professionals time and make OSA diagnosis more accessible. This study aimed to compare the technical quality of type III sleep studies when instructions are provided by face-to-face technical teaching or via video.

Methods: One hundred consecutive patients aged ≥ 18 years with suspected OSA were randomly assigned to receive device placement instructions in person by a technician or through video (50 in each group). The overall quality of the sleep studies was analyzed by determining the number of technically invalid studies. The recording quality of four sensors (pulse oximeter, nasal flow cannula, chest, and abdominal bands) was evaluated by checking for signal artifacts.

Results: The majority (86%) of the studies were valid. 20% of the studies in the face-to-face group and 8% of the studies in the video-instruction group were technically invalid, but no statistically significant difference was found (p = 0.148). The quality of the oximetry signal was better in those who received video instructions (p = 0.05). Regarding the recording quality of the remaining sensors, no significant differences were found.

Conclusions: Type III sleep studies with previous explanation through a video are as effective as those with an explanation performed by a technician, with associated advantages, without increased errors. The quality of the oximetry signal was better in the video group, a critical signal for OSA diagnosis.

III 型睡眠研究的视频演示效果比面对面的技术教学效果差吗？

目的：阻塞性睡眠呼吸暂停（OSA）是最常见的睡眠呼吸障碍。其高发率使诊断成为当务之急。在进行 III 型睡眠研究时，患者通常要接受技术人员的指导。改用视频指导可节省专业人员的时间，并使 OSA 诊断更容易获得。本研究旨在比较通过面对面技术指导或视频指导进行 III 型睡眠检查的技术质量：100 名年龄≥ 18 岁的疑似 OSA 患者被随机分配到由技术人员亲自或通过视频接受设备放置指导（每组 50 人）。通过确定技术上无效的研究次数来分析睡眠研究的总体质量。通过检查信号伪影评估了四个传感器（脉搏血氧仪、鼻导管、胸带和腹带）的记录质量：大多数研究（86%）是有效的。面授组 20% 的研究和视频指导组 8% 的研究在技术上无效，但没有发现统计学上的显著差异（P = 0.148）。接受视频指导者的血氧饱和度信号质量更好（p = 0.05）。其余传感器的记录质量没有发现明显差异：结论：事先通过视频进行解释的 III 型睡眠研究与由技术人员进行解释的研究同样有效，并具有相关优势，但不会增加误差。视频组的血氧饱和度信号质量更好，这是诊断 OSA 的关键信号。

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.
