Summary

This study compares giving 30% versus 100% oxygen to patients just before they wake up from abdominal surgery. The goal is to see if a lower oxygen level reduces the chance of low blood oxygen after the breathing tube is removed. About 590 adults will take part, and the results could help improve recovery in the hospital.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: oxygen
What this could lead to: If 30% oxygen works better, it could lead to a safer, standard way to wake patients after surgery, reducing breathing problems.
What could go wrong: This is an early-stage study with no phase, so results may not change practice. The benefit may be small or not apply to all patients.
