About

Exercise intolerance and sleeping problems are among the most common symptoms experienced by patients with chronic obstructive pulmonary disease (COPD), which is associated with lung dynamic hyperinflation (DH). There was evidence that positive expiratory pressure (PEP), which less costly devices could offer, could reduce DH.

A positive expiratory pressure device improved COPD-related symptoms in more than 70% of patients with COPD.

PEP buddy is an adjunct to current COPD therapies, such as inhalers and pulmonary rehabilitation. It provides a tool for self-management and breathing re-training, reducing dyspnea and improving quality of life.

Full description

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.
