Biological and Mechanical Limitations for Chronic Fast‐Scan Cyclic Voltammetry Sensor Design

Advanced Materials Technologies, EarlyView.
Real‐time detection of neurochemicals has demonstrated value in the field of neuroscience. However, current methods have limitations for use in the chronic setting, which is often the ideal environment for research. This article discusses these limitations, as well as technologies that have been developed to overcome them, and provides recommendations ...

Pulse Wave Analysis

2021
The cardiac output monitoring devices based on pulse wave analysis (PWA) became a standard of hemodynamic management in many selected patients in critical and perioperative care. They are known as “minimally invasive” because the only prerequisite is a conventional arterial catheter.

Pulse wave analysis for the prediction of preeclampsia [PDF]

Journal of Human Hypertension, 2013
Preeclampsia is associated with a number of changes to maternal vascular function. Assessment of arterial stiffness using pulse wave analysis (PWA) has been proposed as a means of predicting preeclampsia before the onset of clinically detectable disease.

Pulse Wave Analysis Techniques

The Handbook of Cuffless Blood Pressure Monitoring, 2019
Pulse wave analysis, or PWA, is a technique based on the morphological analysis of blood pressure waveforms, whose shape reflects crucial information on the properties of the arterial wall and blood pressure itself. Although the first historical developments of PWA date back to the nineteenth century, the technique started to prosper with the ...

Reproducibility of pulse wave velocity and augmentation index measured by pulse wave analysis

Journal of Hypertension, 1998
The aim of this study was to determine the reproducibility of pulse wave velocity (PWV) and augmentation index (AIx) measured using pulse wave analysis (PWA), prior to its use in large-scale clinical trials.Arterial pressure waveforms were recorded and analysed using an established technique (Sphygmocor). Subjects with and without a range of recognized

Reproducibility of pulse wave analysis and pulse wave velocity in patients with type 2 diabetes

Scandinavian Journal of Clinical and Laboratory Investigation, 2013
Patients with type 2 diabetes have increased arterial stiffness and a high incidence of cardiovascular disease compared with non-diabetics. Arterial stiffness and central waveforms can be assessed by carotid-femoral pulse wave velocity (PWV) and pulse wave analysis (PWA) using the SphygmoCor device.

Pulse wave analysis: basic concepts and clinical application in intensive care medicine

Current Opinion in Critical Care, 2023
Purpose of review The measurement of cardiac output (CO) is important in patients with circulatory shock. Pulse wave analysis (PWA) estimates CO continuously and in real-time using the mathematical analysis of the arterial pressure waveform.

Pulse wave numerical analysis

Medical Hypotheses, 1996
The general deterioration of the arterial system is well recognized but not easily measured. Leg pulse waves, generated by the electric impedance plethysmograph, would seem to be a promising method. This study is a mathematical analysis of these pulse waves from the legs. The data were taken from a previous study by the same authors.
