Summary

This study tests whether a new monitoring tool called Oxygen Reserve Index (ORi) can detect low oxygen levels earlier than the standard method during throat surgery. Eighty adults having elective endolaryngeal surgery will be randomly assigned to ORi or standard monitoring. The goal is to see if ORi gives doctors more time to respond before oxygen drops to unsafe levels.

What this could mean

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

Active substance: oxygen monitoring techniques
What this could lead to: If successful, this could lead to a safer way to monitor oxygen levels during surgeries where the airway is shared, reducing the risk of dangerously low oxygen.
What could go wrong: This is a small, early-stage study with only 80 participants, so results may not apply to all patients or surgeries. The new monitoring method may not provide a meaningful advantage over current practice.
