Compare noninvasive breathing supports for breathing failure
Part of Lungs & breathing clinical trials.
This trial compares different ways to help you breathe without a breathing tube: helmet NIV, CPAP, or high-flow nasal oxygen. It aims to see which support works best for people who have sudden (acute) low oxygen levels.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a sudden episode of breathing failure with low oxygen (PaO2/FiO2 ratio 200 or less)
- Your carbon dioxide level is not too high (PaCO2 45 mmHg or less)
- You do not have long-term lung failure or need long-term home oxygen
- You are able to give consent (or a legal representative can)
- You have not already had CPAP or NIV nonstop for more than 24 hours before the screening visit
- You are not pregnant and you do not have certain high-risk conditions (like pneumothorax or cardiogenic pulmonary edema)

This trial tests whether high-flow oxygen delivered through the nose, combined with non-invasive breathing support (a mask that helps you breathe without a tube down your throat), can help patients with sudden severe breathing problems. The goal is to improve oxygen levels and avoid the need for a breathing tube.
This trial tests two ways to measure if non-invasive breathing support (a high-flow nasal cannula or a face mask) will work for patients with respiratory failure. The goal is to help doctors choose the right treatment sooner.
This trial compares two ways to help people with high carbon dioxide levels breathe better using a mask. It aims to find which method works best in the emergency department.
This study compares two ways to help breathing in adults with pneumonia who have low oxygen levels: a noninvasive breathing machine versus high-flow oxygen. It aims to see which option helps patients breathe better and avoid getting worse.
This study is looking at ways to improve non-invasive ventilation, which is breathing support given without a breathing tube. You may be invited if you’re already receiving this kind of support and you agree to take part.
This trial tests different types of noninvasive breathing support (like masks or high-flow nasal oxygen) to see which works best for patients with low oxygen levels. It may be helpful if you are in the hospital, need extra oxygen, and are not already on a breathing tube.
