Summary

During robot-assisted laparoscopic radical prostatectomy (RALRP), patients are placed under general anesthesia and supported with mechanical ventilation. In this study, the effects of two different ventilatory strategies-flow-controlled ventilation (FCV) and volume-controlled ventilation (VCV)-were compared. Using electrical impedance tomography (EIT) to provide real-time assessment of lung status and to guide individualized positive end-expiratory pressure (PEEP) settings, we investigated whether FCV offers superior oxygenation and improved respiratory system mechanics compared with VCV.
