A Noncontact Measurement of Cardiac Pulse Based on PhotoPlethysmoGraphy
Heart rate measurement is important for monitoring people’s phys‐ iological and body state. In this paper, a heart rate measurement methodology based on PhotoPlethysmoGraphy (PPG) signal is proposed. Human face positions are detected and tracked in real time by using facial color videos taken from cameras by non-contact shooting. Signals containing pulse components are extracted from images of ...
متن کاملContinuous blood pressure measurement using the pulse transit time: Comparison to intra-arterial measurement.
Continuous blood pressure (BP) measurement allows the investigation of transient changes in BP and thus may give insights into mechanisms of BP control. We validated a continuous, non-invasive BP measurement based on the pulse transit time (PTT), i.e., BP(PTT), by comparing it with the intra-arterial BP (BP(i.a.)) measurement. Twelve subjects (five females and seven males) were included. BP(i.a...

متن کاملMeasurement 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 کاملModeling of arterial stiffness using variations of pulse transit time
In this paper, a finite element (FE) modeling is used to model effects of the arterial stiffness on the different signal patterns of the pulse transit time (PTT). Several different breathing patterns of the three subjects are measured with PTT signal and corresponding finite element model of the straight elastic artery is applied. The computational fluid-structure model provides arterial elasti...
