PROBLEM TO BE SOLVED: To provide a respiration analysis device which puts a reduced burden on a patient and can actualize a sufferer of sleep apnea syndrome.SOLUTION: According to an embodiment, the respiration analysis device can be worn on a human body. The respiration analysis device comprises: measurement means which measures the acceleration of a wearing person; detection means which detects a movement of the human body on the basis of an outlier in the waveform of a first frequency band out of waveforms indicating the time variation of a measured acceleration; and discrimination means which discriminates whether a detected movement of the human body is a movement caused by respiration.SELECTED DRAWING: Figure 4【課題】患者にかかる負担が小さく、睡眠時無呼吸症候群の患者の顕在化を実現し得る呼吸解析装置を提供すること。【解決手段】実施形態によれば、呼吸解析装置は、人体に装着可能である。この呼吸解析装置は、装着者の加速度を計測する計測手段と、計測された加速度の時間的な変化を示す波形のうち、第1の周波数帯の波形における外れ値に基づいて、人体の動きを検出する検出手段と、検出された人体の動きが呼吸に起因した動きであるかどうかを判別する判別手段とを含む。【選択図】図4
