This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether using a high-flow oxygen mask before general anesthesia helps obese patients stay safer during the early stages of surgery. The study compares how long patients can safely hold their breath after receiving this oxygen treatment, and whether smoking history affects how well it works.
Obese patients can have more difficulty maintaining safe oxygen levels during the early stages of anesthesia. This trial is exploring whether the new high-flow oxygen mask approach gives doctors more time to safely manage the airway before intubation.

If you join this study, you will receive standard anesthesia preparation for your scheduled surgery. Before anesthesia induction, you will receive high-flow oxygen through a nasal mask for 5 minutes. During anesthesia, doctors will carefully monitor how long you can safely hold your breath and measure oxygen levels. The study focuses on the anesthesia preparation phase of your surgery and does not change your actual surgical procedure.
