Summary:
In patients with obesity or obstructive sleep apnea (OSA) undergoing gastroscopy under deep sedation, nasal mask oxygenation significantly reduced the incidences of hypoxemia, subclinical respiratory depression, and severe hypoxemia compared to standard nasal cannula oxygenation, though it was associated with no increase in other sedation-related adverse events.
| PICO | Description |
|---|---|
| Population | Adults aged 18–70 years with obesity or obstructive sleep apnea (OSA) undergoing gastroscopy under deep propofol sedation. |
| Intervention | Nasal mask oxygenation administered during the sedated gastroscopy procedure. |
| Comparison | Standard nasal cannula oxygenation during the same procedure. |
| Outcome | Nasal mask oxygenation significantly reduced:
There were no significant differences in other sedation-related adverse events between groups. |
