New oxygen sensor could give earlier warning for elderly and obese patients under anesthesia
NCT ID NCT07679724
First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study tests whether a device called the oxygen reserve index (ORi) can warn doctors earlier than standard pulse oximetry when an older patient's oxygen level starts to drop during surgery. Researchers are comparing obese and non-obese patients aged 65 and older to see if ORi provides extra warning time. The goal is to improve safety by giving anesthesiologists more time to respond before oxygen reaches dangerously low 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 reserve index (ORi) monitoring device
- What this could lead to
- If ORi provides earlier warnings, it could help anesthesiologists prevent dangerous oxygen drops in elderly and obese patients during surgery.
- What could go wrong
- This is a small observational study, not a treatment trial. The device may not improve outcomes in real-world settings, and results may not apply to all patients.
