Comparison of Three Methods of PEEP Titration During One Lung Ventilation in Prone Position

One-lung ventilation and prone positioning during thoracoscopic esophagectomy is associated with pulmonary complications so lung protection is strongly recommended. Individualization the optimal PEEP level according to the respira¬tory condition of patients has gradually attracted the attention of clinicians. The aim of this study is to compare and evaluate the differences between three different PEEP values in patients who will undergo thoracoscopic esophagectomy receiving either constant PEEP or driving pressure guided individualized PEEP or oxygenation guided individualized PEEP.
