Each participant will receive both oxygenation strategies in a fixed alternating order during four consecutive ECT sessions. The procedures will follow standard anesthesia protocols.\n\nDuring the ECT procedures and the 30-minute recovery period in the post-anesthesia care unit, we will monitor the occurrence of hypoxia (SpO₂ \\\u003C92%), ventilator parameters, vital signs, postoperative confusion within 24 hours, and any reports of dental discomfort.
