【 摘 要 】

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.
