Abstract Study Objectives To assess the relationship between obstructive sleep apnea
(OSA) severity and sleep fragmentation, accurate differentiation between sleep and …

Traditional sleep staging with non-overlapping 30-second epochs overlooks multiple sleep-
wake transitions. We aimed to overcome this by analyzing the sleep architecture in more …

Abstract Study Objectives Accurate identification of sleep stages is essential in the diagnosis
of sleep disorders (eg obstructive sleep apnea [OSA]) but relies on labor-intensive …

The identification of sleep stages is essential in the diagnostics of sleep disorders, among
which obstructive sleep apnea (OSA) is one of the most prevalent. However, manual scoring …

Objective: Obstructive sleep apnea (OSA) is diagnosed using the apnea-hypopnea index
(AHI), which is the average number of respiratory events per hour of sleep. Recently …

Sleep staging is an essential component in the diagnosis of sleep disorders and
management of sleep health. Sleep is traditionally measured in a clinical setting and …

Obstructive sleep apnea (OSA) is a common sleep disorder caused by abnormal breathing.
The severity of OSA can lead to many symptoms such as sudden cardiac death (SCD) …

Purpose Portable sleep monitoring devices with less-attached sensors and high-accuracy
sleep staging methods can expedite sleep disorder diagnosis. The aim of this study was to …

Sleep disorders affect a large portion of the global population and are strong predictors of
morbidity and all-cause mortality. Sleep staging segments a period of sleep into a sequence …

Sleep apnea-hypopnea event detection has been widely studied using various biosignals
and algorithms. However, most minute-by-minute analysis techniques have difficulty …
