In patients with chronic respiratory failure, pulmonary rehabilitation is recognized as an evidence-based treatment in improving exercise capacity, muscle strength, dyspnea, and quality of life. However, optimal SpO2 value during pulmonary rehabilitation in patients with chronic respiratory failure receiving long-term oxygen therapy is unclear.~The present study is randomized to compare the effect of exercise capacity between high SpO2 (Minimum SpO2 94-96%) value during pulmonary rehabilitation and low SpO2 (Minimum SpO2 84-86%) value during pulmonary rehabilitation for the patients with chronic respiratory failure receiving long-term oxygen therapy.
The purpose of this study is to compare the exercise capacity between high SpO2 (Minimum SpO2 94-96%) value during pulmonary rehabilitation and low SpO2 (Minimum SpO2 84-86%) value during pulmonary rehabilitation for the patients with chronic respiratory failure receiving long-term oxygen therapy.
