Objectives
Narrative objectives1 By measuring changes in respiratory mechanics through the use of new ventilators that can measure pulmonary compliance and esophageal pressure, rather than the ventilators attached to the anesthesia machine used during surgery, and by elucidating the respiratory mechanics through new respiratory physiological indicators such as transpulmonary pressure, the mechanisms of postoperative pulmonary complications will be elucidated. Furthermore, the aim is to examine the appropriate pulmonary protective respiratory setting during esophageal cancer surgery.
