Patent ID: 8568440

Claim:
A measuring device for estimating a central arterial blood pressure at a remote site, which includes: (1) means for controlling a pressure change in a cuff during a process of pressurization, decompression or maintenance at a specific pressure value; (2) means for recording and saving oscillometric signals of a pressure in the cuff; and (3) means for analyzing the oscillometric signals of the pressure in the cuff, and for estimating the central arterial blood pressure by real-time analysis of the oscillometric signals of the pressure by performing an equation of estimating the central arterial blood pressure by a known regression formula on the basis of factors (I) systolic blood pressure of pulse volume recording, (II) last phase systolic blood pressure of pulse volume recording, (III) a value of an area below a waveform during systole and an area below a waveform during diastole dividing the area below the waveform during diastole, and (IV) a pressure of reflected wave hiding beneath a waveform of pressure, in which all factors (I) to (IV) are identified or measured from waveforms of the pulse volume recording.
