LMA vs High-flow Nasal Oxygen During ECT in Obese Patients

A supraglottic airway device (i-gel) used to deliver oxygen and assist ventilation during electroconvulsive therapy (ECT) in obese patients. The device is inserted after induction of general anesthesia and removed after spontaneous respiration is restored.

A heated and humidified oxygen delivery system that provides high flow oxygen through nasal prongs. In this study, it is used throughout the ECT procedure to maintain oxygenation in obese patients without the need for invasive airway insertion.
