Independent clinical research


A number of papers have investigated the benefits of bi-level pressure therapy on dyspnea in COPD patients. We’ve summarized this work in a discussion paper you can download and review.

clinical info dyspnea

Dyspnea and its treatment with positive airway pressure during simulated activities of daily living in COPD patients

Activities of Daily Living (ADL) may be limited by exertional dyspnea in patients with advanced COPD. To obtain relief from episodes of dyspnea accompanying these ADL, patients may use bronchodilators or adjuncts such as pursed lip breathing. When symptoms are severe, the ADL may be abandoned altogether. In our study, we evaluated dyspnea and its treatment with Positive Airway Pressure (PAP) given by noninvasive ventilation in seventeen subjects during the Glittre ADL-test, a field test consisting of standardized ADL-like activities.

Impact of positive airway pressure in post-exercise recovery from dyspnea in COPD patients

Dyspnea is the most common symptom limiting the ability of COPD patients to perform activities of daily living. Although there has been research involving the benefit of providing Non Invasive Ventilation (NIV) during exercise, there is little research specifically looking at shortening dyspnea recovery times post exercise only. We evaluated the effect of positive airway pressure (PAP) administered via a NIV device as an adjunct to shortening the duration of dyspnea post-exercise.
