Claim 4:
5. The physical condition determination device according to claim 4,
wherein the systolic blood pressure-related index calculation unit finds the time-series waveform of the systolic blood pressure-related index by using a gradient of the peak values in every predetermined time range,
wherein the diastolic blood pressure-related index calculation unit finds the time-series waveform of the diastolic blood pressure-related index by using a gradient of the bottom values in every predetermined time range, and
wherein the physical condition sudden change determination unit specifies, as the appearance time of the sign of the sudden change in the blood pressure, a time zone in which the time-series waveform of the systolic blood pressure-related index found using the gradient of the peak values in every predetermined time range and the time-series waveform of the diastolic blood pressure-related index found using the gradient of the bottom values in every predetermined time range cross each other and a point appears at which a value of the systolic blood pressure-related index is smaller than a value of the diastolic blood pressure-related index.
