Oxygen levels after heart surgery linked to delirium in 1,000-Patient study
NCT ID NCT07548905
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at 1,000 patients who had heart surgery and were then moved to the ICU. Researchers tracked whether high or low oxygen levels increased the chance of developing delirium, a state of confusion. The goal was to understand how oxygen management might affect recovery after cardiac surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If the results show a clear link, it could lead to better oxygen management in ICUs to reduce delirium after heart surgery.
What could go wrong
This is an observational study, not a treatment trial. It can show a connection but cannot prove that changing oxygen levels prevents delirium.
