DUET Versus Standard Interface for Hypercapnic COPD Patients
Sponsor: Larissa University Hospital
Summary
The goal of this clinical trial is to compare the new asymmetric nasal high flow interface with the conventional high flow nasal cannula in patients with COPD exacerbation. The main questions the study aims to answer are: • Does the use of the asymmetric interface lead to: 1. A greater decrease in the patients' carbon dioxide 2. A greater decrease in respiratory rate and less dyspnea 3. Less need for advanced oxygen therapy measures 4. Same tolerance and comfort 5. Lower heart rate and blood pressure Participants will be asked to: Wear the asymmetric and conventional cannulas for 3 hours each with a 30 minute gap in-between. Arterial blood samples and various clinical parameters will be collected throughout the study period. Researchers will compare the effect of asymmetric versus conventional cannulas to answer the aforementioned questions.

Conditions
Interventions
Asymmetric nasal cannula - DUET
DUET asymmetric nasal high flow interface that fits best to the patients' nostrils (size: one nostril of the patient should be fully occluded) Patients will be crossed-over between the 2 interventions
Conventional nasal high flow cannula
Well-established conventional nasal high flow cannula (size: medium) Patients will be crossed-over between the 2 interventions
