Brief summary
Hypoxia is the most common adverse event in gastrointestinal endoscopes sedated with propofol. The nasal mask oxygen kit has good sealing to ensure an adequate oxygen supply and is convenient and economical.The aim of this randomized study was to determine whether the nasal mask oxygen kit reduces the incidence of hypoxia in gastrointestinal endoscopes procedures.
Interventions
Using the nasal mask oxygen kit for oxygenation.
Using nasal cannula for oxygenation.

Secondary
| Measure | Time frame | Description |
