Title:
PULSE OUTPUT ESTIMATING APPARATUS
Document Type and Number:
Japanese Patent JP3662683
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pulse output estimating apparatus which achieves a continuous noninvasive estimation of a pulse output.
SOLUTION: A pulse output Qrelative is calculated by a pulse output calculation means 84 based on a time constant τ calculated by an expansion period waveform time constant calculation means 82 and an average blood pressure value EBPMEANdetermined by a blood pressure value determining means 76 from a specified relationship (Qrelative=PAV/τ). With a pulse output estimating apparatus thus arranged, the pulse output Qrelative can be continuously estimated in a non-invasion manner thereby achieving a higher reliability in the monitoring of the circulation state of a living being.
