Severe exercise-induced hypoxemia.

Exercise training is an essential component of pulmonary rehabilitation and is associated with improved function and other important outcomes in persons with chronic lung disease. A subset of pulmonary rehabilitation patients experience hypoxemia that may occur or worsen with exercise. For the purpose of this review, severe exercise-induced hypoxemia is defined as an S(pO(2)) of < 89% during exercise, despite use of supplemental oxygen delivered at up to 6 L/min. There is a paucity of evidence and clinical guidelines that address assessment and management of this important manifestation of chronic lung disease. This review presents background of this topic and suggests strategies for assessment, management, and safety measures for patients with severe exercise-induced hypoxemia.

Pulmonary rehabilitation: WHAT WE KNOW AND WHAT WE NEED TO KNOW.

The multidisciplinary treatment of pulmonary rehabilitation (PR), which includes exercise training, self-management education, and psychosocial and nutritional intervention, is now a standard of care for chronic obstructive pulmonary disease (COPD) and has been incorporated into major guidelines. We must now focus efforts on improving its impact and widening its applicability. What is the direction of PR; where does it fit in the comprehensive care of the COPD patient; and how can clinicians best apply this important intervention? This was the charge of the roundtable discussion, Pulmonary Rehabilitation: Moving Forward, involving 20 experts from North America and Europe, which was convened in Fort Lauderdale, Florida, in early 2008. It is not meant to be an exhaustive review; rather, this report summarizes the roundtable proceedings, while providing direction to best position PR into the continuum of COPD care. By consensus, it was agreed upon that although PR is effective for other chronic respiratory diseases, the discussion focus was COPD since most of the evidence base and patient referral are for this disease. These proceedings provide insight into 3 broad areas appropriate for investigation or implementation: positioning PR in an integrated care model for COPD patients; improving the effectiveness of this intervention; and expanding the recognition, application, and accessibility to PR. It is the hope that this document will provide a catalyst for clinicians, investigators, and healthcare policy makers to help realize these goals as well as serve to suggest important areas for future research and development in PR.
