Application of intraoperative lungprotective ventilation varies in accordance with the knowledge of anaesthesiologists: A single-Centre questionnaire study and a retrospective observational study

The benefits of lung-protective ventilation (LPV) with a low tidal volume (6 mL/kg of ideal body weight [IBW]), limited plateau pressure (< 28–30 cm H2O), and appropriate positive end-expiratory pressure (PEEP) in patients with acute respiratory distress syndrome have become apparent and it is now widely adopted in intensive care units.
