Abstract：As an important auxiliary treatment equipment for chronic obstructive pulmonary disease (COPD), respiratory training and
airway clearance techniques are widely used in patients with COPD. At present, oscillatory positive expiratory pressure (OPEP) devices
are convenient, and have both respiratory training and airway cleaning function, which can benefit patients, but its application is used
relatively less. Firstly, this paper introduced the basic function of OPEP devices, which is respiratory training and airway clearance
techniques. After that, the basic principle of OPEP devices was described and the classic devices were introduced. The advantages
and disadvantages of different devices were compared. Finally, the application value of OPEP devices was expounded from the
aspects of symptoms, pulmonary function, quality of life, acute exacerbation and so on. In this paper, we summarized the advantages
and clinical value of OPEP devices in order to benefit the patients with COPD. It is also expected that there will be extensive and indepth
researches in the future to make the devices more optimized and better used in clinical practice.
