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.
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.
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.
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.
阻塞性睡眠呼吸暂停（OSA）是最常见的睡眠呼吸障碍。其高患病率使其诊断成为当务之急。为进行III型睡眠研究，患者通常会收到技术人员的指导。改用视频指导可以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提供指导时III型睡眠研究的技术质量。
连续100例年龄≥18岁疑似OSA的患者被随机分配，一组由技术人员亲自进行设备放置指导，另一组通过视频进行指导（每组50例）。通过确定技术上无效的研究数量来分析睡眠研究的整体质量。通过检查信号伪迹来评估四个传感器（脉搏血氧仪、鼻流量插管、胸部和腹部束带）的记录质量。
大多数（86%）研究是有效的。面对面组20%的研究和视频指导组8%的研究在技术上无效，但未发现统计学上的显著差异（p = 0.148）。接受视频指导的患者的血氧饱和度信号质量更好（p = 0.05）。关于其余传感器的记录质量，未发现显著差异。
通过视频预先解释的III型睡眠研究与技术人员解释的研究一样有效，具有相关优势，且不会增加错误。视频组的血氧饱和度信号质量更好，这是OSA诊断的关键信号。
