Summary

This study compares two ways of giving oxygen during surgery when patients are in the beach chair position (sitting up). One method uses standard pulse oximetry, the other adds a new monitor called the Oxygen Reserve Index (ORi). The goal is to see if ORi guidance reduces the chance of giving too much oxygen, which can be harmful. Eighty adults having elective orthopedic surgery will take part.

What this could mean

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

Active substance: Oxygen Reserve Index (ORi) monitoring
What this could lead to: If successful, this could lead to safer oxygen management during surgery, reducing risks from too much oxygen.
What could go wrong: This is a small, early-stage study with only 80 participants. The new monitoring method may not show clear benefits over standard care.
