    The study compared conventional oxygen therapy, high-flow nasal cannula, and supraglottic jet oxygenation during bronchoscopic procedures under deep sedation.

  • 2

    A total of 150 patients with mild-to-moderate airway stenosis were randomly assigned to one of the three oxygenation strategies.

  • 3

    Supraglottic jet oxygenation significantly reduced the incidence of hypoxemia and severe hypoxemia compared to conventional oxygen therapy.

  • 4

    The SJOV group had higher arterial oxygen levels and lower lactic acid levels than both the conventional oxygen therapy and high-flow nasal cannula groups.

  • 5

    No significant differences were found in endotracheal intubation rates, hemodynamic stability, or procedure duration among the three groups.
