The purpose of this investigation is to use a computational model to compare a
synchronized valveless pulsatile left ventricular assist device with continuous flow left …

Dilated cardiomyopathy is the most common type of the heart failure which can be
characterized by impaired ventricular contractility. Mechanical circulatory support devices …

Purpose Continuous flow left ventricular assist devices (CF-LVADs) generally operate at a
constant speed, which causes a decrease in pulse pressure and pulsatility in the arteries …

Together with new developments in mechanical cardiac support, the analysis of vortex
dynamics in the left ventricle has become an increasingly important topic in literature. The …

This article describes the stroke volume selection and operational design for the toroidal
ventricular assist device (TORVAD), a synchronous, positive-displacement ventricular assist …

Objectives: The analysis of energetic ventricular variable changes during artificial
ventilation, obtained by numerical simulation was done. Twenty-one sets of hemodynamic …

This study proposes a theoretical basis of blood flow volume sensor for arteriovenous fistula
(AVF) of hemodialysis patients in a noninvasive way by means of reflectance-type …

Systolic pressure variation (SPV) and its components (dUp and dDown) have been
demonstrated to be of interest in assessing preload in mechanically ventilated patients. The …

The treatment with a mechanical ventilator is required whenever a patient's respiratory
system becomes unable to keep the concentrations of O2 and CO2 in blood at tolerable …

Purpose Application of a comprehensive, user-friendly, digital computer circulatory model to
estimate hemodynamic and ventricular variables. Methods The closed-loop lumped …
