Patients meeting the criteria of obstructive sleep apnea were included, and all patients signed informed consent, which met the requirements of the ethics Committee of our unit. All subjects were hospitalized patients. Subjects were randomly enrolled into High-flow Nasal Cannula Oxygen Therapy group or Continuos Positive Airway Pressure group for 1 month of treatment. Sleep respiration monitoring data including AHI, blood oxygen saturation decline index (ODI) and minimum blood oxygen saturation were recorded before and after treatment. After one month of the first stage of treatment, patients voluntarily continued to receive treatment and observers were included in the second stage of treatment. HFNC group and CPAP group continue to receive corresponding treatment for 6 months.Before and after the study, sleep respiratory monitoring datas,treatment failure rate，good compliance rate are recorded.

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
