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.

Conditions

• Positive Pressure Ventilation

Interventions

Type	Name	Description
DEVICE	Flow-Controlled Ventilation	Mechanical ventilation delivered in a flow-controlled mode with constant inspiratory and expiratory flow patterns
DEVICE	Volume-Controlled Ventilation	Mechanical ventilation delivered in a volume-controlled mode with constant tidal volume and decelerating inspiratory flow pattern.
