Sleep / apnea central / occlusion type diagnosis support device and diagnosis support method, and sleep apnea central / occlusion type diagnosis support program

摘要

Provided is a sleep / apnea central / occlusion type diagnosis support technology capable of accurately performing a central / occlusion diagnosis of a sleep apnea syndrome (SAS) patient. A raw waveform data storage unit 11 that stores raw waveform data including respiratory motion and heart sounds of the subject, an apnea period detection unit 12 that extracts a respiratory motion frequency component of the raw waveform from the stored raw waveform data and detects an apnea period. , FFT processing unit 13 that performs fast Fourier transform processing on the data related to the apnea period of the raw waveform data to generate PSD in the apnea period, PSD sum value that calculates the power spectrum density (PSD) sum value in a predetermined frequency region The calculation unit 14, the PSD pattern matching determination unit 15 that determines whether the generated PSD pattern matches the central apnea PSD pattern, and the raw waveform and the respiratory motion frequency component of the raw waveform And a display unit 17 for displaying the PSD.
