AB  - Patients with advanced lung disease, especially patients with COPD, suffer from dyspnea at rest that worsens during the performance of even limited physical activities. The causes of dyspnea are multifactorial and are related to structural changes found in the parenchymal compartment of the lung as well as the airway and pulmonary vasculature. Alterations in any of the lung compartments may have negative consequences for the physiological performance of exercise. Respiratory assist devices that attenuate the pathophysiological derangements induced by the underlying lung disease, and/or unload the increased work of breathing, can enhance the performance of exercise, and help to produce more robust training effects in patients with lung disease. Herein we review the data that examines these approaches using respiratory assist devices to improve exercise outcomes in patients with COPD.
