Abstract:
1. A blood pressure measurement apparatus comprising: a sensor configured to gauge blood flow speed in a measurement target blood vessel of a patient; a circuit configured to estimate blood pressure on the basis of results of gauging of the sensor by referencing a correlation formula that indicates correlation characteristics of the blood pressure and the blood flow speed of the patient which have been set in advance; a first input section including a connector configured to connect a first external measurement apparatus performing blood pressure measurement such that first inputs measurement values that are continuously measured by a continuous method at the first external measurement apparatus are continuously input; and a second input section including a connector configured to connect a second external measurement apparatus performing blood pressure measurement such that a second measurement value that is measured by using an intermittent method at the second external measurement apparatus is input; the circuit being further configured to correct the correlation formula by rederiving the correlation formula using the first inputs measurement values which are continuously input by the first input section, and to correct the correlation formula by modifying the correlation formula using the second measurement value which is input by the second external input section.
