RecruitingDevice studyProspective Study to Evaluate High Flow Nasal Cannula With Monitored Anesthesia Care During EBUS BronchoscopyOur objective is to assess whether the use of high flow nasal cannula (Vapotherm, Exeter, NH) with monitored anesthesia care (MAC) during an endobronchial ultrasound (EBUS) bronchoscopy procedure will lead to less procedure interruptions, less hypoxic episodes, shorter duration of hypoxic episodes and shorter procedural durations when compared to regular MAC using a regular nasal canula.
