Arterial pulse wave modelling and analysis for vascular age studies: a review from VascAgeNet

American Journal of Physiology. Heart and Circulatory Physiology, 2023
Arterial pulse waves (PWs) such as blood pressure and photoplethysmogram signals contain a wealth of information on the cardiovascular (CV) system that can be exploited to assess vascular age and identify individuals at elevated CV risk.

Cardiac output estimation by pulse wave analysis using the pressure recording analytical method and intermittent pulmonary artery thermodilution

European Journal of Anaesthesiology, 2020
BACKGROUND Invasive pulse wave analysis is used in peri-operative settings to estimate cardiac output (CO). The ‘pressure recording analytical method’ (PRAM) implemented in the MostCareUp CO monitor is an invasive pulse wave analysis method using high ...

A Multichannel Real-Time Bioimpedance Measurement Device for Pulse Wave Analysis [PDF]

IEEE Transactions on Biomedical Circuits and Systems, 2018
Pulse wave analysis is an important method used to gather information about the cardiovascular system. Instead of detecting the pulse wave via pressure sensors, bioimpedance measurements can be performed to acquire minuscule changes in the conductivity ...

ANALYSIS OF FONTANELLE PULSE WAVE

The Kurume Medical Journal, 1978
The fontanelle pulse wave was recorded with the Marey's tambour, and it was compared with the intracranial pressure that was determined with the instrument to measure intracranial pressure via the anterior fontanelle. The Purin's instrument (1964) was improved in original way for this experiment, and the fontanelle pulse wave was analyzed by the ...

Pulse wave response characteristics for thickness and hardness of the cover layer in pulse sensors to measure radial artery pulse

BioMedical Engineering OnLine, 2018
Background Piezo-resistive pressure sensors are widely used for measuring pulse waves of the radial artery. Pulse sensors are generally fabricated with a cover layer because pressure sensors without a cover layer are fragile when they come into direct ...

Modeling the Pulse Signal by Wave-Shape Function and Analyzing by Synchrosqueezing Transform. [PDF]

PLoS ONE, 2016
We apply the recently developed adaptive non-harmonic model based on the wave-shape function, as well as the time-frequency analysis tool called synchrosqueezing transform (SST) to model and analyze oscillatory physiological signals.
