High-Flow Nasal Oxygyen Therapy During Sedated Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration(EBUS-TBNA)

This study aims to evaluate the effects of high-flow nasal oxygen therapy on respiratory complications, blood gas parameters, and post-procedural recovery in patients undergoing sedated endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Participants will be assigned to receive either high-flow nasal oxygen therapy or conventional oxygen therapy during the procedure. The incidence of respiratory complications, blood gas changes, and recovery outcomes will be compared between the two groups.
