Outline of Final Research Achievements

Mat-type sensors are known as portable monitoring devices for obstructive sleep apnea, and there have been several validation studies of the devices referenced with respiratory disturbance indices on polysomnogram (PSG), and some of them have already been covered by medical insurance in Japan. However, few studies have evaluated the accuracy of the respiratory event detection capability of these devices. We investigated the accuracy of a thin, lightweight, and low-cost sheet-type pressure sensor (sensor sheet), that had been developed at Yamagata University in detecting respiratory rate while patients are lying in bed, and found that the sensor sheet has almost the same measurement accuracy as PSG with standard sensors in a non-contact environment. The sensor sheet may become a non-invasive and accurate measurement tool in the future.

Academic Significance and Societal Importance of the Research Achievements

本研究によって低コストかつ簡便に、終夜睡眠ポリグラフと同等の呼吸検出が可能であることが確認された。将来的に、本研究で用いたシート型圧力センサーを夜間就寝中の呼吸状態モニターや、閉塞性睡眠時無呼吸に対する簡易検査に応用することで、一定の精度を有しながら、低コストかつ簡便な簡易検査装置として社会実装できる可能性がある。
