TLDR
The bedside determination of the ΔPpao/ΔPpa ratio should identify the cases in which Ppao measurements are not valid more reliably than lateral chest x-ray film, thus avoiding misleading interpretations of P pao during PEEP ventilation.About:

Journal ArticleDOI
Central venous pressure measurements improve the accuracy of leg raising-induced change in pulse pressure to predict fluid responsiveness
Karim Lakhal,Stephan Ehrmann,Isabelle Runge,Dalila Benzekri-Lefevre,Annick Legras,Pierre François Dequin,Emmanuelle Mercier,Michel Wolff,Bernard Regnier,Thierry Boulain +9 more
TL;DR: A PLR-induced change in CVP ≥2 mmHg was required to allow clinical usefulness ofPLR-derived indices and ΔPLRPP performed well for predicting fluid responsiveness in deeply sedated patients.
Journal ArticleDOI
Clinical relevance of data from the pulmonary artery catheter.
TL;DR: Technological improvement transforms PAC in a real time integrated physiological device and allows one to observe the impact of therapeutic intervention and take a therapeutic decision to improve determinants of SvO2 with the help of all other PAC parameters.
Journal ArticleDOI
Hemodynamic monitoring in the intensive care unit.
TL;DR: The field of hemodynamic monitoring is rapidly evolving and will probably continue to evolve at this rapid pace over the next 5 to 10 years as new technologies, information management systems, and the understanding of the pathophysiology of critical illness progresses.

The ability of pleth variability index to predict the hemodynamic effects of positive end-expiratory pressure in mechanically ventilated patients under general anesthesia.
Olivier Desebbe,Cécile Boucau,Fadi Farhat,Olivier Bastien,Jean-Jacques Lehot,Maxime Cannesson +5 more
TL;DR: PVI may be useful in automatically and noninvasively detecting the hemodynamic effects of PEEP when VT is >8 mL/kg in ventilated and sedated patients with acceptable sensitivity and specificity.

Invasive measures of left ventricular preload.
Xavier Monnet,Jean-Louis Teboul +1 more
TL;DR: The best prediction of the hemodynamic response to fluid therapy is afforded by functional evaluation of preload responsiveness rather than by static markers of pre load.

Distribution of blood flow in isolated lung; relation to vascular and alveolar pressures.
TL;DR: The left lung from a dog was removed, ventilated with negative pressure, and perfused with venous blood to establish pulmonary arterial, venous, and alveolar pressures that could be varied over a large range.

Influence of positive end expiratory pressure on left ventricular performance
François Jardin,Jean-Christian Farcot,Louis Boisante,Nikita Curien,André Margairaz,J.P. Bourdarias +5 more
TL;DR: It is concluded that decreased cardiac output during PEEP is mediated by a leftward displacement of the interventricular septum, which restricts left ventricular filling.

Pulmonary artery occlusion pressure: clinical physiology, measurement, and interpretation.
Ronald O'Quin,John J. Marini +1 more
TL;DR: This review focuses on the clinical physiologic aspects of the wedge pressure determination, the technical principles of measurement, and the practical application of the information Pw provides.

Estimating left ventricular filling pressure during positive end-expiratory pressure in humans
TL;DR: Methods of estimating LV filling pressure using Ppao measurements under conditions in which increases in Ppc were the primary determinants of differences in the two measurements were examined.

TL;DR: Measurements of net left atrial pressure and stroke work indicated that high levels of PEEP resulted in left ventricular failure, which may have been due to reduced coronary flow secondary to an elevated myocardial interstitial pressure with high level PEEP.
