A wearable device for at-home obstructive sleep apnea assessment: State-of-the-art and research challenges

Abstract: In the last 3 years, almost all medical resources have been reserved for the screening and treatment of patients with coronavirus disease (COVID-19). Due to a shortage of medical staff and equipment, diagnosing sleep disorders, such as obstructive sleep apnea (OSA), has become more difficult than ever. In addition to being diagnosed using polysomnography at a hospital, people seem to pay more attention to alternative at-home OSA detection solutions. This study aims to review state-of-the-art assessment techniq… Show more

“…In this study, we developed an unobtrusive method for HSAT utilizing a piezoelectric rubber sheet sensor. We designated algorithms to extract respiration and ballistocardiogram signals, allowing for the scoring of the respiratory event index (REI) [16,17], as well as measuring the frequency (Fcv) of cyclic variation of heart rate (CVHR) [7,8,18]. The performance of REI and Fcv in classifying sleep apnea severity was assessed using the apnea-hypopnea index (AHI) obtained from the simultaneous polysomnogram as a reference standard.…”

“…Generally, it is believed that the accuracy of sleep apnea detection improves with an increased number of signals measured [ 15 ]. However, considering the convenience of HSAT, it is desirable to minimize the number of sensors used and the effort required to wear them [ 16 ]. Thus, the optimal signal and measurement method should be selected by considering the tradeoff between accuracy and convenience.…”
