PROBLEM TO BE SOLVED: To correctly and easily detect an apnea/hypopnea condition during sleep while remarkably reducing the botheration and burden on a subject.SOLUTION: An electric current applying electrode section 20A supplies an electric current into a cervical region 51 of a living body 50. A measurement electrode section 20B measures an impedance generated in the cervical region 51 by the electric current. An analysis section 13 detects an apnea/hypopnea condition based on the measured impedance of the cervical region 51. An output section 14 outputs the result of detection.COPYRIGHT: (C)2013,JPO&INPIT【課題】被験者の煩わしさや負担を大幅に軽減しつつ、正確かつ容易に睡眠中の無呼吸低呼吸状態を検出する。【解決手段】給電電極部20Aは、生体50の頸部51に電流を流す。測定電極部20Bは、電流により頸部51に生じるインピーダンスを測定する。解析部13は、頸部51のインピーダンスの測定値に基づいて無呼吸低呼吸状態の検出を行なう。出力部14は、検出の結果を出力する。【選択図】図1
