Device and method for central blood pressure estimation |
摘要 |
A sensor unit is brought into contact with a surface of a living body to detect a pulse wave of an artery directly below. A CPU extracts a characteristic point of the pulse wave detected and obtains a second systolic component in the pulse wave using the characteristic point extracted. Then, a variation with time in a systolic blood pressure of a central artery of the living body is estimated using the second systolic component obtained, and an estimated variation with time in the systolic blood pressure is displayed on a display portion. For estimation of the systolic blood pressure, arithmetic with a linear transformation is applied using the second systolic component obtained and a blood pressure of a peripheral artery which is measured beforehand with an electronic sphygmomanometer.
