Anesthesia for Endobronchial Ultrasound (EBUS) may be range from routine bronchoscopy sedation to general anesthesia. During sedation to EBUS increased duration of anesthesia and sedative dosing put patients at increased risk for hypoxic events. To avoid this, oxygen supplementation is mandatory. There are different techniques for oxygen supplementation during the procedure. At this study we will compare to nasal and buccal oxygen supplementations during EBUS.
The purpose of this study is to compare to nasal and buccal oxygen administration in patients undergoing Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration .
