Measurement of Spatial Pulse Wave Velocity by Using a Clip-Type Pulsimeter Equipped with a Hall Sensor and Photoplethysmography
A prototype of a clip-type pulsimeter equipped with a magnetic field-sensing semiconductor Hall sensor was developed. It has a permanent magnet attached in the "Chwan" position to the center of a radial artery. The clip-type pulsimeter is composed of a hardware system measuring voltage signals. To measure spatial pulse wave velocity (SPWV), the signal from the radial artery pulsimeter and that ...
متن کاملMeasurement of Blood Pressure Using an Arterial Pulsimeter Equipped with a Hall Device
To measure precise blood pressure (BP) and pulse rate without using a cuff, we have developed an arterial pulsimeter consisting of a small, portable apparatus incorporating a Hall device. Regression analysis of the pulse wave measured during testing of the arterial pulsimeter was conducted using two equations of the BP algorithm. The estimated values of BP obtained by the cuffless arterial puls...

15 صفحه اولNon-triggered quantification of central and peripheral pulse-wave velocity
PURPOSE Stiffening of the arteries results in increased pulse-wave velocity (PWV), the propagation velocity of the blood. Elevated aortic PWV has been shown to correlate with aging and atherosclerotic alterations. We extended a previous non-triggered projection-based cardiovascular MR method and demonstrate its feasibility by mapping the PWV of the aortic arch, thoraco-abdominal aorta and iliof...
متن کاملMRI estimate of central and peripheral pulse-wave velocity via velocity-encoded projections
Introduction Stiffening of the aorta results in increased pulse wave velocity (PWV), the propagation velocity of the blood motion. Aortic stiffness has been shown to correlate with aging [1], but is also indicative of atherosclerotic alterations and as a measure of cardiovascular risk [2]. Quantification of peripheral PWV (e.g. iliac, femoral and popliteal arteries) has received much less atten...
