NCT ID NCT04136717
First seen Nov 01, 2025 · Last updated Jun 19, 2026 · Updated 34 times
Summary
This study tests a device called FreeO2 that automatically adjusts oxygen levels during noninvasive breathing support. It includes 10 patients with COPD flare-ups or after weight-loss surgery. The goal is to see if the device keeps oxygen saturation in a safe range better than manual adjustments.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
FreeO2 automatic oxygen titration device
What this could lead to
If it works, this could improve oxygen management during breathing support, reducing risks from too little or too much oxygen.
What could go wrong
This is a very small early study with only 10 participants, so results may not apply widely. The device may not work better than standard care.
