Comparison of Several Oxygenation Targets With Different Oxygen Interfaces - Impact on Oxygen Flow Rates

ClinConnect Summary

This clinical trial is studying how different types of oxygen delivery methods, called interfaces, affect the amount of oxygen flow in patients with respiratory issues like COPD, bronchitis, and respiratory failure. Researchers want to understand how these methods can influence oxygen flow rates and the level of carbon dioxide in the blood, especially when using certain types of oxygen masks that can lead to rebreathing.

To participate in this trial, you need to be an adult aged 18 or older who is currently receiving oxygen therapy and has a specific oxygen saturation level (between 88% and 100% with the usual device). However, if you have certain conditions, like severe anemia or if your oxygen flow is very high (over 6 liters per minute), you may not be eligible. If you take part, you can expect to help researchers learn more about how to improve oxygen therapy for patients like you, which could lead to better care in the future. The trial is not yet recruiting participants, so it will start accepting volunteers soon.
