Summary

This trial tests whether giving high-concentration oxygen during a clot-removal procedure can improve recovery for people having a major stroke who arrive at the hospital 6 to 24 hours after symptoms began. Participants are randomly assigned to receive either the oxygen therapy or standard care alongside the procedure. The goal is to see if the extra oxygen protects brain tissue and leads to better function 90 days later.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
high-concentration oxygen (normobaric hyperoxia) delivered through a mask or ventilator
What this could lead to
If it works, this could offer a simple, low-cost way to improve recovery for stroke patients who miss the early treatment window.
What could go wrong
This is a mid-stage trial, and earlier results may not hold up. Oxygen therapy could also cause side effects like lung irritation or worsen outcomes in some patients.
