Arterial Pulse Pressure Variation with Mechanical Ventilation

American Journal of Respiratory and Critical Care Medicine, 2019
Abstract Fluid administration leads to a significant increase in cardiac output in only half of ICU patients. This has led to the concept of assessing fluid responsiveness before infusing fluid. Pulse pressure variation (PPV), which quantifies the changes in arterial pulse pressure during mechanical ventilation, is one of the dynamic ...

Influences of different vasopressors on stroke volume variation and pulse pressure variation

Journal of Clinical Monitoring and Computing, 2015
Pulse pressure variation (PPV) and stroke volume variation (SVV) during mechanical ventilation have been shown to be effective parameters to predict preload responsiveness. Although induced hypertension decreases PPV and SVV, the influences of different vasopressors on PPV and SVV are unknown.

Photoplethysmographic and pulse pressure variations during abdominal surgery

Acta Anaesthesiologica Scandinavica, 2011
BackgroundRespiratory variations in pulse pressure (ΔPP) predict fluid responsiveness during mechanical ventilation. Variations in pulse oximetry plethysmography amplitude (ΔPOP) are proposed as a non‐invasive alternative. Large variations in ΔPOP and poor agreement between ΔPP and ΔPOP are found in intensive care unit patients.

Variation of arterial compliance within the cardiac pressure pulse

Journal of Biomechanics, 1998
Past investigations of in vivo arterial behavior have concentrated on determining material properties based upon the maximum and minimum pressure and diameter measured over a pulse cycle. A new in vivo technique, based upon continuous measurement of pressure and flow, has been developed to study arterial compliance throughout the pulse cycle ...

Influence of Pressure Control Levels on the Pulse Pressure Variations

Shock, 2011
Pulse pressure variation (PPV) is a promising predictor for volume responsiveness. However, recent studies have criticized its validity during small tidal volume (TV) ventilation. The present study evaluated the influence of pressure control level (PCL) on PPV.

Respiratory Variation in Pulse Pressure and Plethysmographic Waveforms

Anesthesia & Analgesia, 2011
Dynamic variables are the best predictors of fluid responsiveness in patients under general anesthesia and mechanical ventilation; namely, respiratory variations in pulse pressure and in the plethysmographic waveform. However, these variables have potential limitations. Our aim was to evaluate their intraoperative applicability.

Pulse pressure variation: where are we today?

Journal of Clinical Monitoring and Computing, 2010
In the present review we will describe and discuss the physiological and technological background necessary in understanding the dynamic parameters of fluid responsiveness and how they relate to recent softwares and algorithms' applications. We will also discuss the potential clinical applications of these parameters in the management of patients under

Pulse pressure variation and ARDS.

Minerva anestesiologica, 2013
Fluid management is a crucial issue in patients with acute respiratory distress syndrome (ARDS). Assessment of preload responsiveness should help to define the best fluid strategy. Arterial pulse pressure variation (PPV), which represents the amplitude of the respiratory changes in arterial pulse pressure, is considered as a marker of preload ...

The influence of the airway driving pressure on pulsed pressure variation as a predictor of fluid responsiveness

Intensive Care Medicine, 2009
Assessing pulse pressure variation (PPV) to predict fluid responsiveness in mechanically ventilated patients with tidal volume (VT) and the impact of VT and airway driving pressure (P(plat) - PEEP) on the ability of PPV for predicting fluid responsiveness.Prospective interventional study.ICU of a university hospital.Fifty-seven mechanically ventilated ...

Pulse pressure variations adjusted by alveolar driving pressure to assess fluid responsiveness

Intensive Care Medicine, 2009
To evaluate the ability of DeltaPP/DeltaP [pulse pressure variations (DeltaPP) adjusted by alveolar pressure variations (DeltaP = Pplat-PEEPtot)] in predicting fluid responsiveness, to compare its accuracy to that of DeltaPP used alone and to evaluate the influence of tidal volume (Vt) on these two indices.Prospective study.A 22-bed general intensive ...
