The role of positive expiratory pressure (PEP) in physiotherapy of patients with cystic fibrosis. Comparison with oscillating positive expiratory pressure (OPEP)
Languages of publication
Physiotherapy plays a very important role in cystic fibrosis. Its basic aim is to regularly clear bronchial passages of mucus which is responsible for exacerbation of bronchoalveolar symptoms. Positive Expiratory Pressure (PEP) and Oscillating Positive Expiratory Pressure (OPEP) are among the most commonly used bronchi clearance methods. It is not entirely clear which technique should be applied in what situations and whether these techniques are similar to other drainage techniques in terms of effectiveness. The aim of this study is to review the literature and analyse the effectiveness of both techniques, to summarise the existing evidence and to point to gaps in the knowledge about this issue.
