Intraoperative Assessment of Fluid Responsiveness in Normotensive Dogs under Isoflurane Anaesthesia

Veterinary Sciences, 2021
The aim of this study was to evaluate the incidence of fluid responsiveness (FR) to a fluid challenge (FC) in normotensive dogs under anaesthesia. The accuracy of pulse pressure variation (PPV), systolic pressure variation (SPV), stroke volume variation (

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:

Comparação entre as variações respiratórias da amplitude de onda pletismográfica da oximetria de pulso e do pulso arterial em pacientes com e sem uso de norepinefrina Comparison between respiratory pulse oximetry plethysmographic waveform amplitude and arterial pulse pressure variations among patients with and without norepinephrine use

Revista Brasileira de Terapia Intensiva, 2009
OBJETIVOS: A variação respiratória da pressão arterial é um bom preditor da resposta a fluidos em pacientes ventilados. Foi recentemente demonstrado que a variação respiratória na pressão arterial de pulso se correlaciona com a variação da amplitude da ...

Pulse pressure variation guided fluid therapy during kidney transplantation: a randomized controlled trial [PDF]

Brazilian Journal of Anesthesiology, 2020
Purpose: Kidney transplantation is the gold-standard treatment for end stage renal disease. Although different hemodynamic variables, like central venous pressure and mean arterial pressure, have been used to guide volume replacement during surgery, the ...

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 ...

2.2 TRANSFER FUNCTION-DERIVED CENTRAL PRESSURE AND CARDIOVASCULAR EVENTS: THE FRAMINGHAM HEART STUDY

Artery Research, 2013
Relations between central versus brachial blood pressure and major cardiovascular disease (CVD) events remain controversial. Central measures derived using radial tonometry and a generalized transfer function as implemented using the SphygmoCor device ...

Pavane for a pulse pressure variation defunct [PDF]

Critical Care, 2013
Hemodynamic management of critically ill patients in the ICU or high-risk patients in the operating room has paradoxically shown progress in terms of outcome after the systematic application of volume responsiveness/flow optimization based on pulse pressure variation and/or stroke volume variation during controlled, positive-pressure ventilation in ...

Change in cardiac output during Trendelenburg maneuver is a reliable predictor of fluid responsiveness in patients with acute respiratory distress syndrome in the prone position under protective ventilation

Critical Care, 2017
Background Predicting fluid responsiveness may help to avoid unnecessary fluid administration during acute respiratory distress syndrome (ARDS). The aim of this study was to evaluate the diagnostic performance of the following methods to predict fluid ...
