COPD
Conditions
Brief summary
Comparison of a conventional non-invasive ventilation to a non-invasive pursed-lip breathing ventilation (PLBV) ventilation in advanced COPD
Detailed description
Intervention: Non-invasive ventilation with dynamic positive pressure during expiration (pursed-lip breathing ventilation, PLBV) Control Conventional bi-level non-invasive ventilation (NIV) with static positive pressures Duration of intervention per patient 3 months as randomized (1:1) followed by 9 months as chosen by patient
Interventions
A non-invasive ventilation device mimicking the pursed lip breathing in COPD patients will be used.
Standard non-invasive ventilation
