Prone positioning attenuates and redistributes ventilator-induced lung injury in dogs.
TL;DR: In this model of lung injury induced solely by mechanical forces, the prone position resulted in a less severe and more homogeneous distribution of ventilator‐induced lung injury, which parallel those previously obtained in oleic acid‐preinjured animals ventilated with higher positive end‐expiratory pressure.

An increase of abdominal pressure increases pulmonary edema in oleic acid-induced lung injury.

TL;DR: In OA-injured lung, the increase of IAP increases the amount of edema, with homogeneous distribution along the cephalocaudal and sternovertebral axis.

Effect of prone position on regional shunt, aeration, and perfusion in experimental acute lung injury.

TL;DR: In a surfactant-deficient model of lung injury, the prone position improved gas exchange by restoring aeration and decreasing shunt while preserving perfusion in dorsal lung regions, and by making the distribution of ventilation more uniform.
Journal ArticleDOI
Oxygenation Response to a Recruitment Maneuver during Supine and Prone Positions in an Oleic Acid–Induced Lung Injury Model
TL;DR: The results suggest that a RM improves oxygenation more effectively with a decreased PEEP requirement for the preservation of the oxygenation response in prone compared with supine position.
Journal ArticleDOI
Role of cyclooxygenase-2 in oleic acid-induced acute lung injury.
TL;DR: The effect of endotoxin on pulmonary perfusion in ALI is therefore the result of a COX-2-mediated increase in prostacyclin production in lung tissue.

Improved oxygenation in patients with acute respiratory failure: the prone position.
TL;DR: Six patients with acute respiratory failure were turned from supine to prone, supporting the upper thorax and pelvis and allowing the abdomen to protrude, and arterial PO2 increased, permitting a decrease in inspired oxygen concentration or positive end-expiratory pressure when prone.

The prone position in ARDS patients. A clinical study.
TL;DR: In this article, the gas exchange and hemodynamics were evaluated before, during, and after a two-hour period of prone position in 13 moderate-severe ARDS patients in both supine and prone positions.

Fractal properties of pulmonary blood flow: characterization of spatial heterogeneity.
Robb W. Glenny,H. T. Robertson +1 more
TL;DR: The heterogeneity of pulmonary blood flow was examined using a fractal analytic procedure, and the results were compared with the traditional gravitational model of flow distribution, suggesting that gravitation plays a secondary role to an underlying process producing heterogeneity.
