Abstract

Provided is a simple sleep state detection device which accurately detects stopped breathing or a hypopnea state during sleeping. A sleep state detection device (2, 3) is characterized by having: an acquisition unit (221, 321) for acquiring beat interval data of a subject in a predetermined period including a sleeping period; an event detection unit (222, 322) for detecting periodic heartbeat fluctuation event data from the beat interval data; an event processing unit (223, 323) for executing a removal processing for removing, from the periodic heartbeat fluctuation event data, periodic heartbeat fluctuation event data for a period in which the beat intervals are within a predetermined range; and an output unit (224, 324) for outputting an apnea indication signal associated with the removed periodic heartbeat fluctuation event data.

Description

technical field [0001] The disclosure relates to a sleep state detection device, a sleep state detection method and a sleep state detection program. Background technique [0002] Sleep apnea syndrome (SAS: Sleep apneasyndrome), which is a disease in which breathing stops or low breathing during sleep, is well known. As a diagnostic method for sleep apnea syndrome, there are sleepers who measure biological activities such as electroencephalogram, eye movement, electrocardiogram, electromyogram, breathing curve, snoring, and arterial blood oxygen saturation throughout the night. A physical examination. However, there is a problem that the scale of the device is large, the test subject needs to be hospitalized, and measurement cannot be easily performed. In addition, comprehensive judgment by a physician or clinical laboratory technician is required. Therefore, there is a high demand for a sleep state detection device that can easily diagnose sleep apnea syndrome. [0003] ...
