![]() ![]() This study will be performed in a sleep lab environment.Īs of March 2017, the new clinical practice guideline for diagnostic testing for adult sleep apnea of the American Academy of Sleep Medicine (AASM) for the first time formulates a strong recommendation that both polysomnography (PSG) and home sleep apnea testing (HSAT) are appropriate diagnostic testing options for uncomplicated adult patients who are at increased risk of moderate to severe sleep apnea.Ĭollop et al. The investigators will also compare the total sleep time (TST) derived by both systems. In order to assess NightOwl's performance, The investigators will compare the respiratory event index (REI), defined as the number of respiratory events per hour of sleep, derived by the NightOwl system, to the AHI obtained from manual analysis of the polysomnography (PSG), which is the gold standard for sleep apnea diagnosis. The software derives actigraphy from the former, and blood oxygen saturation and peripheral arterial tone (PAT), among other features, from the latter. The sensor acquires accelerometer and photoplethysmographic data. The system consists of a sensor placed on the fingertip and a cloud-based analytics software. The objective of this study is to evaluate the performance of a miniaturized sleep apnea test, called NightOwl. This study will be performed in a sleep lab environment. In order to assess NightOwl's performance, the investigators will compare the respiratory event index (REI), defined as the number of respiratory events per hour of sleep, derived by the NightOwl system, to the apnea-hypopnea index (AHI) obtained from manual analysis of the polysomnography (PSG), which is the gold standard for sleep apnea diagnosis. Why Should I Register and Submit Results?.© 2018 American Academy of Sleep Medicine. ![]() Home sleep apnea testing miniaturized photoplethysmography. The NightOwl-REI achieved a close correlation and REI-categorization with the MSSS-AHI, especially in light of the significant inter-scorer variability of the analysis of the PSG. 743, after double-labeling near-boundary participants. 812 and the agreement between the ZOL-AHI and MSSS-AHI was. After categorization of the AHI, the agreement between the NightOwl-REI and the MSSS-AHI was. The NightOwl-REI and ZOL-AHI had a correlation of. 001), which was close to the correlation between the ZOL-AHI and MSSS-AHI (ρ =. The NightOwl-REI had a high correlation with the MSSS-AHI (ρ =. ![]() The respiratory event index (REI) derived by NightOwl (NightOwl-REI), the apnea-hypopnea index (AHI) derived by Ziekenhuis Oost-Limburg (ZOL-AHI), and the AHI derived by YMT (MSSS-AHI) were compared. (YMT) after analysis by the Michele Sleep Scoring System (MSSS). In order to establish an external benchmark, all PSG tests were edited by a somnologist of Younes Medical Technologies Ltd. The software derives actigraphy from the former, and blood oxygen saturation and peripheral arterial tone, among other features, from the latter.ĭata of 101 participants who underwent an in-laboratory polysomnography (PSG), while wearing the NightOwl sensor, were collected. The objective of this study was to evaluate the performance of a miniaturized home sleep apnea test, called NightOwl. ![]()
