description A respiratory waveform analyzer (10), operable to analyze a respiratory waveform, which is generated based on a temporal change of a concentration of a component in respiratory gas of a subject, includes: a respiratory gas concentration generator (100,210) which generates a concentration signal based on an output signal from a sensor (50) that is placed to measure the concentration of the component; a flatness calculator (220) which calculates a flatness indicative of flat degree of the respiratory waveform based on a temporal change of the concentration signal; and a reliability calculator (230) which calculates a reliability of the respiratory waveform based on the flatness and the concentration signal.
