The main questions it aims to answer are:\n\nDoes FCV provide better intraoperative hemodynamic and respiratory stability compared to VCV during laparoscopic bariatric surgery? Is FCV a safe and feasible ventilation strategy under high intraabdominal pressure and position changes required in bariatric surgery?\n\nResearchers will compare FCV group to VCV group to see if FCV improves intraoperative respiratory mechanics and hemodynamic parameters.\n\nParticipants will:\n\nUndergo elective laparoscopic bariatric surgery with BMI \\>40 kg\u002Fm² (ASA I-III) Receive either flow-controlled or volume-controlled ventilation with individualized PEEP and tidal volume of 6-8 ml\u002Fkg predicted body weight Have intraoperative hemodynamic and respiratory parameters monitored at regular intervals, including arterial blood gas analysis Be followed postoperatively for oxygen therapy requirement and intensive care need",[80,81,82],"Obesity, Morbid","Bariatric Surgery (Sleeve Gastrectomy )","Mechanical Ventilation",[84,85,86,87,88],"Flow-controlled ventilation","Volume-controlled ventilation","Respiratory mechanics","Lung-protective ventilation","Bariatric surgery","2026-06-07",{"date":91,"type":92},"2026-06-11","ACTUAL",{"date":94,"type":92},"2026-03-15",{"date":96,"type":76},"2026-08",{"name":5,"class":6},1]
