Respiratory waveform analyzer

PROBLEM TO BE SOLVED: To provide a respiratory waveform analysis device that can accurately obtain noise components in a respiratory waveform. SOLUTION: The respiratory waveform analysis device for analyzing a respiratory waveform generated on the basis of chronological changes in the concentration of a specific component in respiratory gas of a subject, includes: a respiratory airway adapter through which the respiratory gas of the subject flows, and in which a sensor for detecting the concentration of the specific component in the respiratory gas and outputting a signal corresponding to the detected value is disposed therein; a respiratory gas concentration calculation part 210 for generating a concentration signal indicating a level of the concentration based on the signal from the sensor; and a stored water detection part for detecting water remaining in the respiratory airway adapter based on the concentration signal.
