You perceive the movement of the subject, respond to that and the motion sensor which forms the motion signal (30) you include, the device and method are explained. The oxygen measurement sensor (86), it measures oxygen saturation of the subject, responds to that, forms the oxygen measurement signal. The control control equipment (14), the movement which is perceived and the oxygen measurement signal which is perceived is analyzed, was related to the state of the subject who is formed on the basis of the correlation with one features of the oxygen measurement signal and the motion signal, by the oxygen measurement signal the warning which you are wrong is removed. Also other execution form is explained.< Selective figure >It is not被験者の動きを感知し、それに応答して運動信号を生成する運動センサー(30)を含む、装置および方法が説明される。酸素測定センサー(86)は、被験者の酸素飽和度を測定し、それに応答して、酸素測定信号を生成する。制御装置(14)は、感知された動きおよび感知された酸素測定信号を分析し、酸素測定信号と運動信号の一態様との間の相関関係に基づき、酸素測定信号によって生成された被験者の状態に関連した間違った警報を除去する。他の実施形態も説明される。【選択図】なし
