Oxygen showdown: tight vs. liberal targets in heart failure
NCT ID NCT05613218
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether giving heart failure patients with fluid in their lungs a lower oxygen target (90% oxygen saturation) or a higher one (96%) leads to better outcomes. 122 patients were randomly assigned to one of the two groups in the emergency department. The goal was to see which oxygen level reduces fluid in the lungs and improves recovery.

Active substance
Oxygen
What this could lead to
If it works, this could help doctors choose the best oxygen level for heart failure patients, potentially improving recovery and reducing hospital stays.
What could go wrong
This is a small pilot study with only 122 patients, so results may not apply to everyone. The oxygen targets are narrow, and the study may not find a clear benefit or harm.
