Abstract: In the last 20 years, the use of computed tomography (CT) to evaluate thoracic diseases has rapidly gained popularity and CT has become firmly established as an important research and diagnostic modality. In particular, CT has played an important role in improving our knowledge about the pathophysiology of the adult respiratory...

BACKGROUND: Postoperative respiratory failure (PRF) is the most frequent respiratory complication following surgery. OBJECTIVE: The objective of this study was to build a clinically useful predictive model for the development of PRF. DESIGN: A prospective observational study of a multicentre cohort. SETTING: Sixty-three hospitals across...

To investigate the effects of proportional assist ventilation, variable pressure support, and conventional pressure support ventilation on lung function and damage in experimental acute lung injury. DESIGN: : Randomized experimental study. SETTING: University hospital research facility. SUBJECTS: : Twenty-four juvenile pigs. INTERVENTIONS: Pigs...

Background The role of positive end-expiratory pressure in mechanical ventilation during general anaesthesia for surgery remains uncertain. Levels of pressure higher than 0 cm H2O might protect against postoperative pulmonary complications but could also cause intraoperative circulatory depression and lung injury from overdistension. We tested...
