Summary

This study tested whether using a device called the Oxygen Reserve Index (ORI) to guide oxygen levels during rhinoplasty (nose job) surgery could reduce oxidative stress, a type of cell damage. Sixty healthy adults having rhinoplasty were split into two groups: one received standard oxygen levels, while the other had oxygen adjusted based on ORI readings. Researchers measured blood markers of oxidative stress to see if the ORI-guided approach was gentler on the body.

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 device
What this could lead to: If successful, this approach could help reduce oxidative stress during surgeries, potentially improving recovery and reducing complications.
What could go wrong: This is a small, completed trial focused on a specific surgery. The results may not apply to other procedures or patient groups, and the benefits for long-term outcomes are not yet proven.
