    High-flow nasal oxygen (HFNO) demonstrated a 0% desaturation rate during ERCP, outperforming standard mask oxygenation (SM) which had a 59.7% desaturation rate.

  • 2

    In elderly patients, desaturation was 81% in the SM group compared to 0% in both HFNO and general anesthesia (GA) groups.

  • 3

    Minimum SpO₂ levels were significantly lower in the SM group (90%) compared to HFNO and GA groups (both 99%).

  • 4

    Airway interventions were necessary in 31.4% of SM patients, while only 5.4% of HFNO patients required such interventions.

  • 5

    HFNO had the highest volumetric oxygen consumption at 500 L, compared to 175 L for SM and 34.5 L for GA, indicating its resource intensity.
