Hypertension, 2011 Cardiovascular refers to the Cardio (heart) and vascular (blood vessels). The system has two major functional parts: central circulation system and systemic circulation system. Central circulation includes the pulmonary circulation and the heart from where the pulse wave is generated. Systemic circulation is the path that the blood goes from and to the

Pulse wave analysis measurements: important, underestimated and undervalued parameters in cardiovascular health problems [PDF]
Frontiers in Cardiovascular Medicine, 2023 BackgroundCentral aortic stiffness is established as a reliable measure of cardiovascular disease. While pulse wave velocity (PWV) analysis measures arterial distensibility, risk profile of cardiovascular diseases can be expanded with following pulse ...

Estimation of pulse pressure variation and cardiac output in patients having major abdominal surgery: a comparison between a mobile application for snapshot pulse wave analysis and invasive pulse wave analysis. [PDF]
J Clin Monit Comput, 2021 Pulse pressure variation (PPV) and cardiac output (CO) can guide perioperative fluid management. Capstesia (Galenic App, Vitoria-Gasteiz, Spain) is a mobile application for snapshot pulse wave analysis (PWAsnap) and estimates PPV and CO using pulse wave ...

Assessment of pulse rate variability by the method of pulse frequency demodulation [PDF]
BioMedical Engineering OnLine, 2005 Background Due to its easy applicability, pulse wave has been proposed as a surrogate of electrocardiogram (ECG) for the analysis of heart rate variability (HRV). However, its smoother waveform precludes accurate measurement of pulse-to-pulse interval by

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 ...

Overnight pulse wave analysis to assess autonomic changes during sleep in insomnia patients and healthy sleepers. [PDF]
PLoS One, 2020 Insomnia has been associated with increased cardiovascular (CV) risk, which may be linked to sympathetic activation. Non-invasive overnight pulse wave analysis may be a useful tool to detect early signs of autonomic changes during sleep in insomniacs ...

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.

Numerical Modeling of Pulse Wave Propagation in a Stenosed Artery using Two-Way Coupled Fluid Structure Interaction (FSI) [PDF]
arXiv, 2018 As the heart beats, it creates fluctuation in blood pressure leading to a pulse wave that propagates by displacing the arterial wall. These waves travel through the arterial tree and carry information about the medium that they propagate through as well as information of the geometry of the arterial tree.

Second harmonic generation and pulse shaping in positively and negatively spatially dispersive nanowaveguides: comparative analysis [PDF]
Optical and Quantum Electronics, 48(2), 1-10, (2016), 2015 Comparative analysis of second harmonic generation in ordinary and backward-wave settings is presented. Extraordinary properties of frequency doubling nonlinear optical reflectivity and pulse shaping through phase matching of ordinary and backward electromagnetic waves in the nanowaveguides with mixed negative/positive spatial dispersion is ...

The refractive index and wave vector in passive or active media [PDF]
Phys. Rev. A79, 023839 (2009)., 2009 Materials that exhibit loss or gain have a complex valued refractive index $n$. Nevertheless, when considering the propagation of optical pulses, using a complex $n$ is generally inconvenient -- hence the standard choice of real-valued refractive index, i.e. $n_s = \RealPart (\sqrt{n^2})$.
