Mechanical Ventilation in Surgical Patients

This is an investigator-initiated, international, multicenter, prospective, cross-sectional study that aims to 1) describe the incidence and types of postoperative pulmonary complications (PPCs), 2) describe patient demographics, baseline characteristics, and intraoperative ventilation management, 3) describe the occurrence of intraoperative adverse events (IAEs), and 4) their associations with PPCs, 5) assess the practice of intraoperative mechanical ventilation. Patients will be eligible for participation if: 1) adult and 2) receiving intraoperative ventilation during general anesthesia for surgery. Patients receiving ventilation outside of an operating room as well as patients receiving intraoperative ventilation during extracorporeal life support will be excluded
