Changes in Oxygen Saturation During Fiberoptic Bronchoscopy: High-Flow Nasal Cannula versus Standard Oxygen Therapy

BACKGROUND: Hypoxemia is a relatively common complication in stable patients during fiberoptic bronchoscopy (FOB). To prevent this complication, high-flow nasal cannula (HFNC) has been described as an alternative to standard oxygen therapy. However, the advantages of HFNC over standard oxygen therapy in acute care patients receiving supplemental oxygen before FOB performed with an oral approach are unknown. METHODS: was set at 0.40. Hemodynamic, respiratory dynamics, and gas exchange data were collected at baseline, before, during, and 24 h after FOB. RESULTS: = .01, respectively). CONCLUSIONS: compared with standard oxygen therapy.
