Interventions

High-flow nasal oxygenPROCEDURE

High-flow nasal oxygen will be applied to the patients using Optiflow system through nasal openings during sleep endoscopy. Pulse oximetry will be monitored continuously. Otorhinolaryngologist will observe the degree of upper airway obstruction during sleep endoscopy.

Low-flow nasal oxygenPROCEDURE

Low-flow nasal oxygen will be applied to the patients through nasal openings using conventional nasal cannula during sleep endoscopy. Pulse oximetry will be monitored continuously. Otorhinolaryngologist will observe the degree of upper airway obstruction during sleep endoscopy.
