This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
During a sedated stomach exam (gastroscopy), patients with obesity are at higher risk of low blood oxygen levels because extra belly fat can make breathing harder. This trial is testing whether high-flow nasal cannula oxygenation—a newer, more powerful way to deliver oxygen through the nose—works better than a standard oxygen mask at keeping oxygen levels stable during the procedure.
Patients with obesity, especially excess belly fat, have smaller lung capacity and are more vulnerable to breathing problems when sedated. Early evidence suggests that high-flow nasal cannula may be safer and more effective for these patients, but more research is needed to confirm this.

You would be randomly assigned to receive either high-flow nasal cannula oxygen or standard mask oxygen during your scheduled sedated stomach exam. Both groups receive sedation and have the gastroscopy procedure performed normally. The main difference is how oxygen is delivered to you during the procedure. Researchers will measure your blood oxygen levels at the end of the exam to compare how well each method works.
