Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Proportion of patients requiring at least one minor airway intervention during ERCP (chin lift, secretion suctioning, oropharyngeal airway insertion, or conversion from conventional nasal cannula to high-flow nasal cannula). The outcome was assessed prospectively during the procedure and documented on a standardized data collection form by the attending anesthesiology team. | — |
Secondary
| Measure | Time frame |
|---|---|
| Distribution of airway intervention types (chin lift, secretion suctioning, oropharyngeal airway insertion, conversion CNC?HFNC) and their associations with demographic and clinical variables (age, sex, ASA status). Episodes of oxygen desaturation (SpO2 < 90%) were additionally recorded as a secondary safety parameter. | — |
