Outline of Research at the Start

本研究では,睡眠障害の約6割を占める睡眠時無呼吸症候群(sleep apnea syndrome:SAS)に着目し,寝具の下に敷いた無拘束型センサを用いてSASを判定する手法を考案する.具体的には,睡眠中の「覚醒」に着目したSAS判定法を確立し,従来手法の問題(低呼吸判定の限界と努力呼吸の誤判定)と,医師の診断の問題(SAS状態を過小評価する問題)の解決を目指す.

Outline of Final Research Achievements

This research focuses on the sleep apnea syndrome (SAS), proposes the non-contact SAS detection method based on “wake” in sleep stage instead of “respiration” during sleep in order to solve the problems of the conventional SAS detection, and shows that the proposed method succeeds to derive the high accuracy of SAS detection. This research has also revealed that the sleep stage of the healthy human subjects tends to become a “wake” when the body movement is large and tends to become a “non-REM” when the body movement is small, while the sleep stage of the SAS patients shows the opposite tendency in addition to the same tendency.

Academic Significance and Societal Importance of the Research Achievements

学術的意義としては,SASの主たる原因である「呼吸」に着目するのではなく,睡眠中の「覚醒」に着目した新しいSAS判定法を確立し,従来手法の問題(低呼吸判定の限界と努力呼吸の誤判定)を克服したことである.社会的意義としては,無拘束型のマットセンサを用いた提案手法によってSASを早期に発見することで,糖尿病・高血圧・心筋梗塞・脳梗塞のリスクを低減させ,SASによる不眠からくるヒューマンエラーや産業・交通事故を削減し,労働生産性の低下を抑制することが可能となる.
