TLDR
Using adult guinea‐pigs, an experimental model in which alveolar surfactant phospholipids are removed by repeated lung lavage in viao, and in which the short‐term survival of the animals is ensured by artificial ventilation is proposed.
Abstract
Using adult guinea-pigs, we have developed an experimental model in which alveolar surfactant phospholipids are removed by repeated lung lavage in vivo, and in which the short-term survival of the animals is ensured by artificial ventilation. Blood gases, parameters of lung mechanics, and histologic and electron microscopic findings indicate that the lavage procedure induces a condition similar to the adult respiratory distress syndrome. We propose that our technique might be used for evaluation of pharmacological agents and various forms of artificial ventilation which have been suggested for treatment of this disease.

Improvement of Gas Exchange, Pulmonary Function, and Lung Injury With Partial Liquid Ventilation: A Study Model in a Setting of Severe Respiratory Failure

TL;DR: In this paper, the authors evaluated gas exchange, pulmonary function, and lung histology during gas ventilation of the perfluorocarbon-filled lung compared with gas ventilation in severe respiratory failure.

Dynamics of lung collapse and recruitment during prolonged breathing in porcine lung injury.

TL;DR: OA-injured lungs were significantly more unstable than lungs injured by bronchoalveolar lavage or endotoxin infusion, and expiration times <0.6 s are required to avoid cyclic alveolar collapse during mechanical ventilation without extrinsic positive end-expiratory pressure.

Effect of Il-1 Blockade on Inflammatory Manifestations of Acute Ventilator-Induced Lung Injury in a Rabbit Model

TL;DR: IL-1 is a mediator of acute inflammation due to ventilator-induced lung injury and had no effect on the decline in dynamic compliance and oxygenation seen in saline-treated hyperoxic/hyperventilated rabbits.

High peep decreases hyaline membrane formation in surfactant deficient lungs

TL;DR: Animals in the high PEEP group had a significantly greater arterial PO2 than those in the low PEP group, but the mean survival time for each group was similar.

Comparison of lung protective ventilation strategies in a rabbit model of acute lung injury.

TL;DR: Both lung protective strategies were associated with improved oxygenation, attenuated inflammation, and decreased lung damage, however, in this small-animal model of acute lung injury, an open lung strategy with deliberate hypercapnia was associated with significant hemodynamic instability.

TL;DR: Intensive therapy may modify the acute syndrome so as to permit the development of a previously unrecorded abnormality of hyaline-membrane disease.

Pathogenesis of bronchopulmonary dysplasia following hyaline membrane disease.

TL;DR: It is concluded that the most important factor in the pathogenesis of BPD following HMD is mechanical trauma to the lung from the use of excessively high peak airway pressures during mechanical ventilation.

TL;DR: It is concluded that respiration of the newborn has a profound effect both mechanically and metabolically upon the liberation and elaboration of surface-active material.

Effect of pulmonary lavage on lung lecithin synthesis in the Syrian hamster.

TL;DR: Bronchopulmonary lavage with 0.15 m saline stimulated the uptake of [1,2-14C]choline into both the surface-active dipalmitoyl lecithin (DPL) and the unsaturated leCithins (UPC) of Syrian hamster lung, consistent with the view that alveolar lecitins are secreted by the tissue into the alveoli and that unsaturatedLecithins are the precurs
