Abstract

This study aimed to assess the effect of BiPAP®, by nasal mask, on exercise tolerance and respiratory muscle strength in patients with a clinical and spirometric diagnosis of moderate/severe COPD (FEV1 < 60% of predicted). Ten patients of 59.4±8.9 years old, with FEV1/FVC <70% of predicted level, were treated with 30 minutes of BiPAP® (IPAP:10 and 15 cmH2O; EPAP:4 cmH2O), three days per week, during two months. Before and after the treatment, spirometry, inspiratory (MIP) and expiratory (MEP) muscle strength and the distance walked in six minutes (6MWT) were measured. We observed a significant increase (Wilcoxon, p<0.05) in the mean values of MIP (from -55±17 to -77±19, respectively), MEP (from 75±20 to 109±36, respectively) and walking distance (from 349±67 to 448±75). Based on these results, we concluded that BiPAP® improves respiratory muscle strength and exercise tolerance in these COPD patients.

RLAE’s authorship concept is based on the substantial contribution by each of the individuals listed as authors, mainly in terms of conceiving and planning the research project, collecting or analyzing and interpreting data, writing and critical review. Indication of authors’ names under the article title is limited to six. If more, authors are listed on the online submission form under Acknowledgements. The possibility of including more than six authors will only be examined on multicenter studies, considering the explanations presented by the authors.
Including names of authors whose contribution does not fit into the above criteria cannot be justified. Those names can be included in the Acknowledgements section.
 Authors are fully responsible for the concepts disseminated in their manuscripts, which do not necessarily reflect the editors’ and editorial board’s opinion.
