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.

Pulse wave extraction and dual domain analysis

Dianzi Jishu Yingyong, 2019
Two methods for measuring pulse wave using either a pressure or an optical sensor are studied and compared. A model for determining the optimal external force for restraining the pressure sensor is proposed. Pulse waves are measured on 20 volunteers. The

Pulse wave analysis and pulse wave velocity techniques: are they ready for the clinic? [PDF]

Hypertension Research, 2010
interestingly describe animportant factor when arterial stiffness is clini-cally assessed: subject’s body position. Althoughthis is an important question, especially ifwe want to bring this research tool to the clinicin a regular basis, there are several other factorsthat should be considered.

Pulse Wave Analysis to Estimate Cardiac Output [PDF]

Anesthesiology, 2020
Pulse wave analysis enables cardiac output to be estimated continuously and in real time. Pulse wave analysis methods can be classified into invasive, minimally invasive, and noninvasive and into externally calibrated, internally calibrated, and uncalibrated methods.
