About this trial
The goal of this clinical trial is to compare the effects of home high-flow nasal cannula (HFNC) therapy and noninvasive ventilation (NIV) in patients with stable chronic hypercapnic respiratory failure. The main questions it aims to answer are:
* Does HFNC or NIV reduce blood carbon dioxide levels more effectively? * How well do patients tolerate and adhere to each therapy? * Are there differences in oxygen saturation, respiratory rate, and quality of life between the two treatments?
Participants Will:
* Use either HFNC (myAirvo2®) or NIV (Trilogy Evo®) every night for at least 4 hours over a 6-week period. * Visit the hospital for checkups and arterial blood gas tests at the end of each 6-week period. * Switch to the alternate device after six weeks as part of the crossover study design. * Have their device usage recorded and analyzed.

Treatments tested in this trial
High-Flow Nasal Cannula
DeviceTo compare the effects of NIV (Trilogy Evo®) and HFNC (myAirvo2®) in patients with chronic hypercapnic COPD.
Noninvasive Ventilation
Deviceto compare the effects of NIV (Trilogy Evo®) and HFNC (myAirvo2®) in patients with chronic hypercapnic COPD
Treatment groups
Trial outcomes
Primary outcomes
PaCO2
Arterial blood gas analysis will be performed three times to assess the improvement of hypercapnia, the primary outcome, by measuring pH, PaCO₂, PaO₂, HCO₃-, and SpO₂.
Secondary outcomes
TCO2
Transcutaneous CO₂ (SenTec V-Sign, SenTec AG, Switzerland) will be measured three times as a surrogate marker for hypercapnia.
Compliance
During the six-week application period of each device, the actual average daily usage time and the percentage of days with at least four hours of usage (number of days with ≥4 hours of use/ total number of applied days) ×100 will be assessed.
