Title:
ARTERIAL PRESSURE ESTIMATION DEVICE, ARTERIAL PRESSURE ESTIMATION SYSTEM, AND ARTERIAL PRESSURE ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/196144
Kind Code:
A1
Abstract:
This arterial pressure estimation device is provided with a control unit that, when at least one site of a blood vessel downstream of the aorta is compressed in such a manner as to gradually decrease the pressure, acquires, for each heartbeat, sensor data indicating a timing at which blood flow that has occurred at the at least one site is detected as a blood flow timing, records the value of the pressure corresponding to each blood flow timing, corrects the value of the pressure corresponding to a blood flow timing included in an inhalation period of a respiratory cycle, and estimates a change over time in the arterial pressure by referring to the sensor data acquired and the pressure value recorded and corrected.
