Obstructive Sleep Apnea
Conditions
Brief summary
The purpose of this study is to investigate the utility of high-flow nasal oxygen during sleep endoscopy in obstructive sleep apnea patients.
Interventions
PROCEDUREHigh-flow nasal oxygen
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.
PROCEDURELow-flow nasal oxygen
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.
