PEP Buddy Impact on Breathing, Exercise, and Sleep Quality in COPD Patients
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.
