"PURPOSE: Yoga-derived breathing has been reported to improve gas exchange in patients with chronic heart failure and in participants exposed to high-altitude hypoxia. We investigated the tolerability and effect of yoga breathing on ventilatory pattern and oxygenation in patients with chronic obstructive pulmonary disease (COPD). . . . CONCLUSION: We conclude that short-term training in yoga is well tolerated and induces favorable respiratory changes in patients with COPD."
