Lung protective ventilation and thoracic anesthesia

We appreciate the different comments on the study that we performed and published recently (1). The Pulmonary surgery with protective ventilation (PPV) trial compared lung ventilation using large tidal volume without positive end expiratory pressure (PEEP), i.e., a traditional ventilator strategy frequently used during anaesthesia in the last 25 years, to the lung PPV (LPV).
