NCT ID NCT03835741
First seen Nov 01, 2025 · Last updated Jun 21, 2026 · Updated 36 times
Summary
This study tested whether an automated oxygen device (FreeO2) could reduce hospital stays for people with sudden worsening of COPD, compared to standard manual oxygen adjustment. Only 17 people took part before the study was stopped early. The goal was to see if the device could safely keep oxygen levels in a healthy range and speed up recovery.

What this could lead to
If it works, this could reduce hospital stays for COPD patients by automatically adjusting oxygen levels, freeing up hospital resources.
What could go wrong
The trial was terminated early with only 17 participants, so results are limited. Automated oxygen may not work for all patients or settings.
