Objective: To validate the performance of a single-belt type 3 portable monitor Alice NightOne for diagnosis of obstructive sleep apnea and its reliability in remote data transmission. Methods: Our study included two parts: in-laboratory Alice NightOne (ANO) monitoring (ANO lab ) and home sleep apnea testing (HSAT) using ANO (ANO home ). For ANO lab , the participants underwent polysomnography (PSG) with ANO lab simultaneously. For ANO home , the participants completed unattended overnight ANO home out of sleep center and PSG was performed in another night. The ANO recordings were transmitted to cloud database wirelessly in addition to traditional wire transmission. Message digest-5 (MD5) algorithm was utilized to verify the integrity of the cloud data. Results: Ninety-one ANO lab and 170 ANO home recordings were analyzed. Both the respiratory event index (REI) on ANO lab and that on ANO home were lower than the corresponding apnea-hypopnea index (AHI) on PSG (24.9 ± 20.5 events/h vs 31.6 ± 25.0 events/h, and 26.7 ± 17.0 events/h vs 35.3 ± 21.2 events/h respectively, P < 0.001). Bland-Altman analysis of REI on ANO lab versus AHI on PSG showed a mean difference (95% confidence interval) of − 6.7 (− 8.4, − 4.9) events/h. For REI on ANO home versus AHI on PSG, the difference is − 8.0 (− 9.9, − 6.0) events/h. With threshold of REI ≥ 5 events/h for OSA diagnosis, ANO home had 98.8% sensitivity, 90.0% specificity, 99.4% positive predictive value. The MD5 algorithm verified the iden...
