INTRODUCTION: The polysomnography is inconvenient and complex in diagnosing obstructive sleep apnea-hypopnea syndrome. Diagnostic potency of more novel contactless monitoring devices are needed to be validated to screen individuals with obstructive sleep apnea-hypopnea syndrome. The study aimed to evaluate the diagnostic value of a novel contactless sleep monitoring device in obstructive sleep apnea-hypopnea syndrome. METHODS: Demographic features and parameters of monitoring devices were collected from adults with suspected obstructive sleep apnea-hypopnea syndrome from September 2023 through March 2024. All participants were monitored with polysomnography and a novel contactless sleep monitoring device simultaneously. RESULTS: A total of 231 adults with suspected obstructive sleep apnea-hypopnea syndrome were included in the study. In the mild, moderate and severe groups, the accuracy of the novel monitoring device was 96.97%, 85.71% and 85.71%, respectively, with a mean accuracy of 89.36%. The area under the receiver operating characteristic curve of the three groups were 0.9981, 0.9318 and 0.9486, respectively. The sensitivities were 100.00%, 87.50% and 72.00%, respectively. The specificity was 72.00%, 80.95% and 98.32%, respectively. The positive predictive values were 96.71%, 92.45% and 97.59%, respectively. Negative predictive values were 100.00%, 70.83% and 79.05%, respectively. Among 231 subjects, 162 (70.12%) had the same severity classification for both devices. The apnea-hypopnea indexes, total respiratory events and average heart rates were highly correlated between the two devices (p < 0.001). CONCLUSION: The novel contactless sleep monitoring device is capable of detecting respiratory events during sleep, serving as an effective supplement for preliminary screening of obstructive sleep apnea-hypopnea syndrome.
