RESUMO
BACKGROUND: Adults with cystic fibrosis (CF) suffer from abnormally thick mucus that is difficult to clear from the airways. Different airway clearance techniques (ACTs) can be used to clear secretions and non-invasive ventilation (NIV) can be used as an adjunct to these techniques. ACTs are ideally introduced at the time of diagnosis and thereafter modified throughout the patient's lifespan and disease progress. PURPOSE: The research aim was to describe adult patients' views and experiences with using NIV as an adjunct to ACT. METHOD: Eighteen adults with CF were interviewed about their experiences with using NIV during ACT. Semi-structured interviews were conducted and analyzed in accordance with qualitative content analysis. RESULTS: The results gave rise to the overall theme 'Becoming Friends with NIV' and six associated categories: 1) getting a sense of control and feedback; 2) getting support; 3) dealing with doubt; 4) finding the rhythm; 5) feeling the effects; and 6) finding their own motivation. The findings represent a learning process for adults during the implementation stages of NIV; the physiotherapist was found to play a key role in this process. CONCLUSION: 'Becoming Friends with NIV' involves a learning process for adults with CF. To facilitate this learning process, different aspects should be taken into account so as to promote independence and self-management, which in turn allows the patient to experience the treatment as meaningful. The findings are relevant to physiotherapists working with adults and NIV, as improved insight into and understanding of the relationship may have a positive influence on the outcome and success of NIV usage.
