Can High-Flow oxygen make it easier to breathe without a ventilator?
NCT ID NCT07724392
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This study compares three methods of supporting breathing during a spontaneous breathing trial — the test used to see if a patient can be safely taken off a ventilator. The methods are a standard T-piece, pressure support ventilation, and high-flow humidified oxygen. The goal is to measure how much energy patients expend to breathe with each method. The trial enrolls 30 adults in the ICU who have been on a ventilator for more than 48 hours and are at high risk of extubation failure.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- high-flow humidified oxygen delivered via a device normally used for tracheostomies
- What this could lead to
- If high-flow oxygen reduces the work of breathing during weaning, it could lead to a better method for deciding when to remove the breathing tube, potentially reducing complications.
- What could go wrong
- This is a small, early physiological study in 30 people, not a large trial. It measures breathing effort, not patient outcomes, so even positive results may not translate to real-world benefits.
