These conditions of poor pulmonary aeration favor postoperative respiratory complications and are responsible for excess mortality in the perioperative period.\n\nAlveolar recruitment maneuvers (ARMs) are ventilatory strategies used during general anesthesia that aim to restore lung aeration with Positive End Expiratory Pressure (PEEP) sufficient to keep the lungs open afterwards. This pulmonary hyperinflation not only has a major impact on hemodynamics but also presents a risk of barotrauma. ARM is currently performed without precise measurement of the pressures prevailing in the lung.\n\nAdvanced monitoring is now available and integrated into the latest-generation ventilators and includes the combination of Transpulmonary pressure (TPP) and Electro-Impedance Tomography \" (EIT) measurements.\n\nThe aim of this observational study is to measure and record advanced respiratory monitoring data in a minimally invasive way, during alveolar recruitment tests routinely performed for the target population (obese, prone, laparoscopic surgery). Describe and a posteriori analyze the recorded data and establish a relationship between the PEEP values set by conventional ARM and those determined by advanced monitoring combining EIT and PTP for the same patient.",[25,26,27],"General Anesthesia","Ventilator-Induced Lung Injuries","Postoperative Respiratory Complications",[29,30],"Ventilator optimization","Ventilator induced lung injury","NOT_YET_RECRUITING","2026-02-17",{"date":34,"type":35},"2026-02-18","ACTUAL",{"date":37,"type":21},"2026-05",{"date":39,"type":21},"2028-05",{"name":41,"class":42},"Assistance Publique - Hôpitaux de Paris","OTHER"]
