PEP devices have been wildly used to reduce breathing frequency and expiratory flow limitation, change breathing patterns, improve gas exchange, as well as result in less airway collapse and air-trapping in patients with COPD.
Increasing COPD disease severity promotes a negative impact on exercise tolerance and magnifies the level of disability. Physical activity programs appear to safely ameliorate these COPD consequences, conferring beneficial effects on dyspnea and health-related quality of life.
The combination of PEP during aerobic exercise helps to get the most benefits from the exercise for a longer time and little dyspnea and fatigue.
