First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study looked at whether giving extra oxygen during heart surgery (when a heart-lung machine is used) affects kidney function afterward. 104 adults having elective heart surgery were randomly assigned to receive either high or normal oxygen levels. The main goal was to see if extra oxygen could reduce kidney problems. The study is complete, but because it's a small pilot, the results are not definitive.

extra oxygen (hyperoxia)
What this could lead to
If it works, this could point toward safer oxygen levels during heart surgery to protect the kidneys.
