Cardiac output estimation using pulse wave analysis-physiology, algorithms, and technologies: a narrative review.

open access: yesBritish Journal of Anaesthesia, 2020
Pulse wave analysis (PWA) allows estimation of cardiac output (CO) based on continuous analysis of the arterial blood pressure (AP) waveform. We describe the physiology of the AP waveform, basic principles of PWA algorithms for CO estimation, and PWA ...

Brachialis Pulse Wave Measurements with Ultra-Wide Band and Continuous Wave Radar, Photoplethysmography and Ultrasonic Doppler Sensors

open access: yesSensors, 2020
The measurement and analysis of the arterial pulse wave provides information about the state of vascular health. When measuring blood pressure according to Riva-Rocci, the systolic and diastolic blood pressure is measured non-invasively with an ...

The Effect of an Angiotensin Receptor Blocker on Arterial Stiffness in Type 2 Diabetes Mellitus Patients with Hypertension [PDF]

open access: yesDiabetes & Metabolism Journal, 2011
BackgroundHypertension and type 2 diabetes mellitus are major risk factors for cardiovascular disease. This study analyzed the changes in central aortic waveforms and pulse wave velocity as well as related parameters after treatment with valsartan, an ...

Pulse wave analysis in normal pregnancy: a prospective longitudinal study. [PDF]

open access: yes, 2009
Outside pregnancy, arterial pulse wave analysis provides valuable information in hypertension and vascular disease. Studies in pregnancy using this technique show that vascular stiffness is raised in women with established pre-eclampsia.

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.

Pulse Transit Time-Pulse Wave Analysis Fusion Based on Wearable Wrist Ballistocardiogram for Cuff-Less Blood Pressure Trend Tracking

open access: yesIEEE Access, 2020
The objective of this study was to investigate the efficacy of pulse transit time (PTT)-pulse wave analysis (PWA) fusion in cuff-less blood pressure (BP) trend tracking based on the wearable wrist ballistocardiogram (BCG).

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.

Pulse pedestal suppression using four-wave mixing in an SOA [PDF]

open access: yes, 2008
Experimental results are presented demonstrating how four-wave mixing in a semiconductor optical amplifier can be used to remove pulse pedestals introduced due to nonlinearities which occur upon pulse propagation in an optical system.

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
