CENTRAL BLOOD PRESSURE ESTIMATION PARAMETER CALIBRATION METHOD, CENTRAL BLOOD PRESSURE MEASUREMENT METHOD AND CENTRAL BLOOD PRESSURE MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To propose new technique for measuring a central blood pressure.SOLUTION: Blood pressure measurement to measure a diastolic blood pressure of a peripheral artery (e.g. a radial artery) is performed a plurality of times. Blood vessel diameter measurement to measure a diastolic blood vessel diameter as a blood vessel cross section index value in the diastole of a central artery (e.g. a carotid artery) is performed a plurality of times. Parameters (e.g. a stiffness parameter) related to blood pressure estimation processing to estimate a central blood pressure from the blood vessel diameter of the central artery is calibrated by use of measurement results of the blood pressure measurement and the blood vessel diameter measurement.
