Comparative study of pressure- and volume-controlled ventilation on pulse pressure variation in a model of hypovolaemia in rabbits
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
Background and objective: Dynamic indices represented by systolic pressure variation and pulse pressure variation have been demonstrated to be more accurate than filling pressures in predicting fluid responsiveness. However, ...
Simulation of active control using fuzzy logic applied to a pulse combustor
(2002-01-01)
This work analyzes an active fuzzy logic control system in a Rijke type pulse combustor. During the system development, a study of the existing types of control for pulse combustion was carried out and a simulation model ...

A Comparison Between Pulse Pressure Variation and Right End Diastolic Volume Index as Guides to Resuscitation in a Model of Hemorrhagic Shock in Pigs
(LIPPINCOTT WILLIAMS & WILKINS, 2009)
Background: Different hemodynamic parameters including static indicators of cardiac preload as right ventricular end-diastolic volume index (RVEDVI) and dynamic parameters as pulse pressure variation (PPV) have been used ...
Arterial pulse pressure variation predicting fluid responsiveness in critically ill patients (Retracted article. See vol. 31, pg. 542, 2009)
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
In critically ill patients, it is important to predict which patients will have their systemic blood flow increased in response to volume expansion to avoid undesired hypovolemia and fluid overloading. Static parameters ...
Influence of tidal volume on pulse pressure variation and stroke volume variation during experimental intra-abdominal hypertension
(BioMed Central Ltd., 2015)
BACKGROUND:
Pulse pressure variation (PPV) and stroke volume variation (SVV) are frequently used to assess fluid responsiveness in critically ill patients on mechanical ventilation (MV). There are many factors, in addition ...

Influence of ventilatory settings on static and functional haemodynamic parameters during experimental hypovolaemia
(LIPPINCOTT WILLIAMS & WILKINS, 2009)
Background and objective The influence of ventilatory settings on static and functional haemodynamic parameters during mechanical ventilation is not completely known. The purpose of this study was to evaluate the effect ...
Pulse oximetry wave variation as a noninvasive tool to assess volume status in cardiac surgery
(Faculdade de Medicina / USP, 2009)
OBJECTIVE: To compare variations of plethysmographic wave amplitude (ΔPpleth) and to determine the percent difference between inspiratory and expiratory pulse pressure (ΔPp) cutoff values for volume responsiveness ...
