High-flow nasal oxygen versus breathing mask support for severe COPD flare-ups

This trial is testing whether nasal high flow—a newer breathing support method that delivers warm, humidified oxygen through nose prongs—works as well as non-invasive ventilation (a breathing mask attached to a ventilator) for treating severe COPD flare-ups in the emergency department. Both methods help your lungs remove carbon dioxide and improve your blood oxygen levels. The study will compare how quickly each treatment helps patients breathe easier and stabilize.

When COPD gets severely worse, patients need breathing support urgently, but the standard mask-based ventilation can be uncomfortable and hard to tolerate. This medication offers a gentler alternative that might be easier to use while being just as effective, potentially helping more patients get the care they need.
