Hyperoxia effects on brain blood flow in ICU patients
Part of Eyes & vision, Genetic & congenital clinical trials.
This trial studies how giving extra oxygen (hyperoxia) affects blood flow in the brain for patients on a breathing machine in the intensive care unit. The goal is to see if short bursts of higher oxygen levels are safe and how they change brain activity.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older and in the intensive care unit.
- You are on a breathing machine (ventilator) for less than 72 hours.
- You have a small tube in your artery to monitor blood pressure continuously.
- Your carbon dioxide level in the blood is between 35 and 45 mmHg (a normal range).
- You are able to get a clear ultrasound signal through your temple to measure brain blood flow.
- Your doctor thinks it's safe for you to receive a short increase in oxygen.

This trial tests two ways of using a breathing machine (ventilator) in the ICU. One method is more gentle on the lungs, and the goal is to see if it helps patients recover faster.
This study checks how much oxygen is in your body during anesthesia for a planned brain or spine procedure. It aims to see if a new monitor can safely track oxygen levels without extra blood tests.
This trial compares three ways of giving extra oxygen to people with low blood oxygen levels: a face mask with continuous pressure, a noninvasive ventilator, or high-flow oxygen through the nose. The goal is to see which method helps people avoid needing a breathing tube.
This trial tests whether giving extra oxygen (called hyperoxia) to people who may be having a stroke, right in the ambulance on the way to the hospital, can help protect their brain and improve recovery. The goal is to start treatment as early as possible after stroke symptoms begin.
This trial looks at how the lung and brain communicate during serious breathing problems. If you are in the ICU with a new breathing issue and need high-flow oxygen therapy, researchers want to study your brain and lung activity together.
This trial tests a closed-loop system that automatically adjusts the oxygen level in your breathing tube, aiming to keep your oxygen levels in a safe range with less need for manual changes. It may help if you are in the ICU, need a breathing machine, and have low blood oxygen despite receiving extra oxygen.
