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

open access: yesEuropean 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 ...

Influence of Blood Compressibility on Pulse Wave Propagation Properties Based on Elastic Thin-Walled Tube Theory

open access: yesPhysical Activity and Health, 2023
Pulse wave carries abundant physiological and pathological data about the human body. Understanding the effect of blood compressibility on the transmission qualities of pulse waves is necessary to detect, cure, and prevent cardiovascular problems.

Overnight pulse wave analysis to assess autonomic changes during sleep in insomnia patients and healthy sleepers

open access: yesPLoS 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 ...

Spectral method of photoplethysmogram processing for screening of atherosclerosis

open access: yesJournal of Biomedical Photonics & Engineering, 2017
The paper is devoted to the analysis of the existing indicators for the diagnostic of arterial vessels condition and the development of new ones based on the contour analysis of the pulse wave. The performed analysis of the techniques used to process the

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

open access: yesJournal of clinical monitoring and computing, 2020
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 ...

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

open access: yesHypertension 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.

Analysis of the Radial Pulse Wave and its Clinical Applications: A Survey

open access: yesIEEE Access, 2021
The arterial pulse wave is a physiological signal which can reflect the function of the human cardiovascular system. Owing to the measurement being convenient and safe, radial pulse waves have been often used in noninvasive monitoring of human health ...

Assessment of pulse rate variability by the method of pulse frequency demodulation

open access: yesBioMedical 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

Aortic Pulse Wave Analysis Is Not a Surrogate for Central Arterial Pulse Wave Velocity [PDF]

open access: yesExperimental Biology and Medicine, 2009
Arterial Stiffness (AS) is a primary cardiovascular risk factor. AS increases myocardial oxygen demand and LV work and decreases coronary perfusion. Pulse Wave Velocity (PWV) is considered the gold standard for assessing AS. However, PWV testing is time consuming and impractical in the clinical setting.

Changes in AZGP1 Serum Levels and Correlation With Pulse Wave Velocity After Kidney Transplantation

open access: yesFrontiers in Cardiovascular Medicine, 2021
Background: Zinc-alpha 2-glycoprotein (AZGP1), a secreted protein with ubiquitous tissue expression, has been controversially linked to the risk of cardiovascular disease.
