<P>PROBLEM TO BE SOLVED: To accurately grasp noise components of a respiratory waveform. <P>SOLUTION: A respiratory waveform analyzer is provided which analyzes a respiratory waveform generated on the basis of the change in time lapse of the concentration of a specific component in respiratory gas of a subject. The respiratory waveform analyzer includes respiratory gas concentration generators 100 and 210 which generate concentration signals on the basis of an output signal from a sensor placed to measure the concentration of the specific component, a flatness calculator 220 which calculates a flatness indicative of flat degree of the respiratory waveform on the basis of the change in time lapse of the concentration signals, and a reliability calculator 230 which calculates reliability of the respiratory waveform on the basis of the flatness and the concentration signals. <P>COPYRIGHT: (C)2011,JPO&INPIT |
