An interventional study of HFNOT in Hypoxia, sponsored by Seoul National University Hospital. Completed at 1 site in Korea, Republic of. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2019-04-19.

The purpose of this study is to determine the efficacy and safety of nasal high flow oxygen therapy during diagnostic bronchoscopy.
Hypoxemia is frequently seen during diagnostic bronchoscopy. Nasal prong or other existing oxygen supply methods are often difficult to maintain adequate oxygenation during bronchoscopy. In particular, bronchoscopy to patients already showing hypoxemia can be dangerous even though applying conventional oxygen therapy. Thus, we want to elucidate the usefulness of nasal high flow oxygen therapy to hypoxemic patients undergoing diagnostic bronchoscopy.

Success rate of bronchoscopy
Success is defined as completion of planned diagnostic procedure with the oxygen saturation or partial pressure of oxygen in arterial blood was similar to the level of before the procedure. Failure is defined as incompletion of planned diagnostic procedure due to sustained hypoxemia or else. Furthermore failure is defined as hypoxemia(SaO2 \<88%) was developed more than 2 times even though planned procedure was completed.
