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:

Invasive Hemodynamic Monitoring
TL;DR: There is little data to support which interventions should be performed and which are unnecessary in the ICU, and many physicians using these interventions, have little understanding of the monitors and are often unable to apply the data to problem-solving.

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

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.

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.
