What the trial is, and whether it could suit you

Abdominal laparoscopy is widely utilized due to its benefits, including minimal invasiveness, improved cosmetic outcomes, and shorter hospital stays. However, the use of intraoperative pneumoperitoneum and general anesthesia with mechanical ventilation may lead to postoperative pulmonary complications, such as atelectasis. This condition can result in diminished respiratory mechanics and impaired gas exchange. In recent years, intraoperative lung-protective mechanical ventilation techniques, including recruitment maneuvers (RMs) and positive end-expiratory pressure (PEEP) strategies, have gained popularity. These approaches aim to prevent the repeated collapse and reopening of alveoli, thereby reducing the risk of atelectasis. Nonetheless, determining the optimal PEEP level for individual patients remains a complicated and unresolved issue. Electrical impedance tomography (EIT) is a be
