Exercise limitation is a characteristic feature of chronic respiratory diseases such as COPD and is associated with poor outcomes including decreased functional status and health-related quality of life and increased mortality. The mechanisms responsible for exercise limitation are complex and include ventilatory limitation, cardiovascular impairment, and skeletal muscle dysfunction. ⋯ Exercise training, a core component of pulmonary rehabilitation, improves exercise capacity by addressing many of these mechanisms that, in turn, can potentially slow the decline of lung function, reduce the frequency of exacerbations, and decrease mortality. This article will discuss the mechanisms of exercise limitation in individuals with chronic respiratory disease, primarily focusing on COPD, and provide an overview of exercise training and its benefits in this patient population.

Pulmonary rehabilitation (PR) is a highly effective intervention for persons with chronic respiratory diseases, resulting in improvement in exercise capacity, dyspnea, health-related quality of life, mood, reduced hospitalization, and improved survival and cost savings post-COPD hospitalization. Despite demonstrated effectiveness, PR is underutilized in part due to lack of awareness, limited access, and inadequate PR reimbursement. Poor payment is a long-standing barrier to PR's financial stability and access. ⋯ There is an important need to address inadequate PR access in rural settings. Potential opportunities to improve PR referrals and access include exploration of PR synergies with value-based care models that emphasize high-quality care and cost savings. Development and use of effective PR provider tools and resources may help address the above challenges as well as financially benefit PR programs.

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. ⋯ 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.

Pulmonary Rehabilitation: A Look Back, a Look Forward.
Pulmonary rehabilitation (PR) is a comprehensive approach to the management of patients with chronic lung disease that encompasses exercise, education, and psychosocial support. The development of PR programs began in the mid-20th century with the appreciation that exercise provided real benefit in chronic lung disease and that effective disease management involved patient education focused on medications, lifestyle changes, and lifelong regular exercise. Initially PR was primarily facility-based, but today PR is extending into the home with telemedicine, and this is encouraging a real partnership of patients and professionals supporting self-management. ⋯ Access is still very limited for a variety of reason (logistics, financial, patient motivation) that need to be addressed. More focused and personalized exercise programs and monitoring strategies that encourage a patient's lifetime commitment to the principles of PR need to be developed and refined. The opportunity to really impact important clinical outcomes exists with PR, and this needs to be exploited.

Pulmonary rehabilitation (PR) is one of the most effective therapies for chronic respiratory diseases, yet it is significantly underutilized. There are several patient-related, geographic, societal, and health system-related barriers to PR. People with chronic respiratory disease face a collectively high burden of treatments including health care provider visits, medications, oxygen and other durable medical equipment, and providers' recommendation to undertake PR may be considered an added burden more than a likely benefit. ⋯ A limited number of multidisciplinary HCPs trained in PR likely also contributes to limited access to PR for patients. Collectively, these multifaceted barriers to PR create unacceptable health care disparities. Strategies to address barriers to PR are urgently needed in order to enable individuals who need to receive it.
