An interventional study of High-flow nasal oxygen and Low-flow nasal oxygen in Obstructive Sleep Apnea, sponsored by Yonsei University. Completed at 1 site in South Korea. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2022-07-05.
Sponsored by Yonsei University · Not applicable, Interventional, and Treatment
The purpose of this study is to investigate the utility of high-flow nasal oxygen during sleep endoscopy in obstructive sleep apnea patients.
2,263 studies on the registry are indexed under Sleep Apnea, Obstructive; 465 are open to participants now.
This study's enrollment of 24 is below the median of 53 across 1,490 interventional studies indexed under Sleep Apnea, Obstructive.

Exclusion Criteria:
High-flow nasal oxygen will be applied to the patients through nasal openings using Optiflow system during sleep endoscopy. Pulse oximetry will be monitored continuously. Otorhinolaryngologist will observe the degree of upper airway obstruction during sleep endoscopy.
Procedure: High-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.
Procedure: Low-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.
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.
oxygen saturation value
Pulse oximetry will be monitored continuously during sleep endoscopy. Oxygen saturation value will be recorded during the procedure.
Time frame: For 15 minutes during sleep endoscopy. At Day 0.
Ran from Jul 2020 to primary completion in Mar 2022, 20 months.
Of 511 non-industry interventional studies with no phase under Sleep Apnea, Obstructive, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 53. This study's 20 months is below that.
Counting every sponsor, half of 621 studies reached it within 26 months; a quarter within 12 and three quarters within 50.
