Pulse pressure variation, stroke volume variation and dynamic arterial elastance [PDF]

Critical Care, 2011
We read with interest the recent article by Monge Garcia and colleagues [1]. We have two comments regarding this interesting physiological study. First, although we support their observation [2], their explanations may lead to some confusion. Indeed, the Edwards Vigileo™ system-FloTrac™ sensor calculates stroke volume (SV) using the equation:

Stroke volume versus stroke volume variations as guidance for fluid therapy in major abdominal surgery

International journal of health sciences, 2022
Background: The aim of the present study was for comparison of stroke volume versus stroke volume variations as guidance for fluid management under guide directions of electrical cardiometry, during major abdominal surgeries. The primary outcome was to compare between two fluid infusion protocols, regarding the haemodynamic changes, whereas secondary ...

The Impact of Individualized Hemodynamic Management on Intraoperative Fluid Balance and Hemodynamic Interventions during Spine Surgery in the Prone Position: A Prospective Randomized Trial

Medicina, 2022
Background and Objectives: The effect of individualized hemodynamic management on the intraoperative use of fluids and other hemodynamic interventions in patients undergoing spinal surgery in the prone position is controversial.

Influence of breathing on variation in cardiac stroke volume at the onset of cycling

European Journal of Applied Physiology, 2021
During cycling, the variation in cardiac stroke volume (SVV) is similar to that at rest. However, SVV may be influenced by ventilation at the start of cycling, e.g., by a Valsalva-like maneuver used to stabilize the body. This study evaluated the influence of ventilation on SV during initiation of cycling.Ten healthy recreationally physical active ...

Cardiopulmonary interactions—which monitoring tools to use?

Frontiers in Physiology, 2023
Heart-lung interactions occur due to the mechanical influence of intrathoracic pressure and lung volume changes on cardiac and circulatory function. These interactions manifest as respiratory fluctuations in venous, pulmonary, and arterial pressures ...

Evaluation of least significant changes of pulse contour analysis-derived parameters

Annals of Intensive Care, 2019
Background Many maneuvers assessing fluid responsiveness (minifluid challenge, lung recruitment maneuver, end-expiratory occlusion test, passive leg raising) are considered as positive when small variations in cardiac index, stroke volume index, stroke ...

The ultrasonic cardiac output monitor (USCOM) as a tool in evaluating fluid responsiveness in pediatric patients underwent emergency surgery

Bali Journal of Anesthesiology, 2019
Background: Assessment fluid adequacy in pediatric patients underwent surgery is a challenge for anesthesiologists. Hemodynamic parameters used as fluid monitoring sometimes don't accurately provide valid information.

Stroke volume variation and indexed stroke volume measured using bioreactance predict fluid responsiveness in postoperative children [PDF]

British Journal of Anaesthesia, 2015
Postoperative fluid management can be challenging in children after haemorrhagic surgery. The goal of this study was to assess the ability of dynamic cardiovascular variables measured using bioreactance (NICOM®, Cheetah Medical, Tel Aviv, Israel) to predict fluid responsiveness in postoperative children.Children sedated and mechanically ventilated, who

Pulse pressure variation and stroke volume variation under different inhaled concentrations of isoflurane, sevoflurane and desflurane in pigs undergoing hemorrhage

Clinics, 2015
OBJECTIVES: Inhalant anesthesia induces dose-dependent cardiovascular depression, but whether fluid responsiveness is differentially influenced by the inhalant agent and plasma volemia remains unknown.

Serial semi-invasive hemodynamic assessment following pericardiectomy for chronic constrictive pericarditis

Annals of Cardiac Anaesthesia, 2017
Objectives: This study was designed to prospectively investigate the effects of pericardiectomy via median sternotomy on intra- and postoperative hemodynamics by a new semi-invasive device (Flotrac/VigileoTM monitor) using arterial pressure waveform ...
