BLOOD PRESSURE RATIO CALCULATION DEVICE, BLOOD PRESSURE RATIO CALCULATION METHOD, BLOOD PRESSURE RATIO CALCULATION PROGRAM, AND RECORDING MEDIUM RECORDING SAID PROGRAM
A blood pressure ratio calculation device is a device for calculating a maximum-minimum blood pressure ratio corresponding to a ratio between a maximum blood pressure value and a minimum blood pressure value of an inspection target, and includes an input unit for inputting a relative blood pressure waveform corresponding to temporal change in relative blood pressure of the inspection target, a spectrum generation unit for generating a relative blood pressure waveform spectrum by performing Fourier transform on the relative blood pressure waveform, and an analysis unit for calculating the maximum-minimum blood pressure ratio on the basis of the relative blood pressure waveform spectrum.
