Domiciliary Nasal High Flow and Patient Outcomes in Chronic Hypercapnic Respiratory Failure in the United Kingdom

This study is an investigator-initiated, unblinded, multi-centre, one arm pre and post interventional study evaluating the use of nasal high flow over twelve weeks, upon self-reported quality of life in adults aged 18 and above, with COPD or OHS and CHRF. This is not a comparator trial and will provide preliminary information on the intervention in a group of individuals who cannot comply with current guideline recommended therapy (with all strategies used to address any barriers to current treatment usage). This study will therefore aim to evaluate if this treatment offers effective outcomes in this difficult to treat population thus reflecting the variations in practice and choices that occur for this group of individuals in real practice. Ethical approval will be obtained from the research ethical committee of Brighton and Sussex. Informed consent will be obtained from all willing participants.
