REM Sleep Classification with Respiration Rates

Abstract

Polysomnagraphy, the method evaluating the sleep quality, is the reliable and standard method. However, to perform it, subject has to attach many sensors to their body. It seems intrusive, tangled and interrupting the subjects sleep. For the sake of monitoring the daily sleep pattern, simple method measuring the biosignal nonintrusively is needed. At that point, respiration is a beneficial signal, because it can be easily acquired by check the change of the thorax or abdomen. Respiration is one of the representatives of the reflection of the autonomic nervous system. According to the transition of the sleep stages, autonomic nervous system also changes and it can be shown by respiration.In this study, REM and non-REM sleep is classified by only using respiration for the 3 subjects. To enhance the performance, activity signal acquired by load-cell installed bed is added to divide the wake and REM sleep. At the results, hypnograms with polysomnagraphic data is compared with them. It can be seen that high correlation between the REM sleep and increasing pattern of the respiration rates.

Assess Sleep Stage by Modern Signal Processing Techniques

“…The above physiological facts hint that the respiratory pattern of the recorded breathing signal during sleep might well reflect the sleep stage. There have been some reported studies of the sleep stage from analyzing the respiratory signal [13], [14], [15], [16], [17]. In [13] (resp.…”

“…There have been some reported studies of the sleep stage from analyzing the respiratory signal [13], [14], [15], [16], [17]. In [13] (resp. [14]), an averaged respiratory rate over a fixed window is used to estimate the REM and NREM (resp.…”

Alternating diffusion maps for multimodal data fusion

“…Those physiological phenomena motivated various studies to explore the relation between the sleep stage and the patterns in the respiratory signals, e.g. [6,16,38]. Physiologically, these variations are not originated from the same controller, and phenomenologically do not have the same patterns in the recorded time series.…”

Tracking Vital Signs During Sleep Leveraging Off-the-shelf WiFi

“…Request permissions from permissions@acm.org. the vital signs with our sleep quality can further enable sleep apnea diagnosis and treatment [1], treatment for asthma [2] and sleep stage detection [3]. However, the traditional way to monitor vital signs during sleep requires a patient to perform hospital visits and wear dedicated sensors [4], which are intrusive and costly.…”
