This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial compares two different nasal oxygen delivery devices for people experiencing a flare-up of COPD (chronic obstructive pulmonary disease) with high carbon dioxide levels in their blood. The new device being tested is called the DUET asymmetric nasal high flow interface. Researchers believe this new device may help your lungs clear carbon dioxide more effectively than the standard nasal oxygen cannula, which could make breathing easier and reduce the work your lungs have to do.
When COPD flares up and carbon dioxide builds up in your blood, it can be serious and hard to treat. The new treatment may offer a better way to help your body remove this harmful carbon dioxide without needing to go on a breathing machine.

You will receive oxygen therapy through one nasal device first, then cross over to receive oxygen through the other device — researchers will randomly decide which one you try first. During your time in the emergency department, doctors will monitor your breathing, blood oxygen levels, and carbon dioxide levels to see how well each device works for you. The study is designed so you experience both treatments, allowing researchers to compare which one helps you breathe better.
