ReviewPostoperative respiratory failure: pathogenesis, prediction, and prevention.
This review discusses our present understanding of postoperative respiratory failure (PRF) pathogenesis, risk factors, and perioperative-risk reduction strategies. ⋯ PRF is a life-threatening event that is challenging for the surgical team. Risk prediction scales based on large population studies are being developed and validated. We need high-quality trials of preventive measures, particularly those related to ventilator use in both high risk and general populations.

This review discusses the role of chest ultrasound in diagnosis and management of acute respiratory distress syndrome (ARDS) and the most recent technical progresses in this field. ⋯ An ultrasound-integrated approach combining lung ultrasound and echocardiography should be recommended as a suitable technique to manage ARDS during diagnosis, mechanical ventilation setting, and weaning.

ReviewWhich is the most important strain in the pathogenesis of ventilator-induced lung injury: dynamic or static?
To discuss the relative role of dynamic and static tissue deformation (strain) generated by inflation of tidal volume and application of positive end-expiratory pressure in the pathogenesis of ventilator-induced lung injury. ⋯ Large lung dynamic strain is more harmful than equivalent static strain.
