The pattern and outcome of noninvasive ventilation (NIV) use in patients with acute or chronic respiratory disease other than COPD is not well known. The aims of this study were to investigate trends over time in underlying respiratory diseases, use of NIV, and outcomes in COPD and non-COPD patients with acute respiratory failure. ⋯ Over time, respiratory diseases have changed in non-COPD subjects and trends in the use and efficacy of NIV differ between COPD and non-COPD subjects. Mortality remained stable while the severity of illness in subjects increased. In COPD and non-COPD subjects, transition from NIV to IMV was associated with a poorer prognosis.

Pleural liquid and kinetic friction coefficient of mesothelium after mechanical ventilation.
Volume and protein concentration of pleural liquid in anesthetized rabbits after 1 or 3h of mechanical ventilation, with alveolar pressure equal to atmospheric at end expiration, were compared to those occurring after spontaneous breathing. Moreover, coefficient of kinetic friction between samples of visceral and parietal pleura, obtained after spontaneous or mechanical ventilation, sliding in vitro at physiological velocity under physiological load, was determined. ⋯ Protein concentration of pleural liquid after mechanical ventilation was also similar to that occurring after spontaneous ventilation. Coefficient of kinetic friction after mechanical ventilation was 0.023±0.001, similar to that obtained after spontaneous breathing.

Comparative Study Observational StudyEvaluation of a new index of mechanical ventilation weaning: the timed inspiratory effort.
The performance of most indices used to predict ventilator weaning outcomes remains below expectation. The purpose of this study was to evaluate a new weaning index, the timed inspiratory effort (TIE) index, which is based on the maximal inspiratory pressure and the occlusion time required to reach it. ⋯ The TIE index performed better than the best weaning indices used in clinical practice.

Efficacy of veno-venous extracorporeal membrane oxygenation in severe acute respiratory failure.
The objective of this study was to evaluate our institutional experience with veno-venous (VV) extracorporeal membrane oxygenation (ECMO) in patients with severe acute respiratory failure (ARF). ⋯ VV ECMO is an excellent, life-saving treatment option in patients suffering from acute and life-threatening respiratory failure due to various causes, especially trauma, and early use of VV ECMO therapy improved outcomes in these patients.
