Sleep state detection device, sleep state detection method and sleep state detection program

摘要

A simple sleep state detection device with high precision for detecting respiratory arrest or hypopnea during sleep is provided. The sleep state detection devices 2 and 3 include acquisition units 221 and 321 for acquiring the subject's beating interval data in a predetermined period including the sleep period, and detecting periodic heart rate fluctuation event data from the beating interval data. an event detecting unit (222, 322) for performing an exclusion process for excluding periodic heart rate fluctuation event data for a period in which the beat interval falls within a predetermined range from the periodic heart rate fluctuation event data; It is characterized in that it has an output unit (224,324) for outputting an apnea indicator signal related to the fluctuation event data.
