New oxygen device boosts COPD exercise capacity in small trial

This study tested whether a special high-flow oxygen device could help people with COPD exercise more during pulmonary rehab. Thirty patients were split into two groups: one did standard rehab, the other used the device during aerobic training. The device was safe and easy to use, and those who used it could walk at a steeper incline on the treadmill, showing a trend toward better exercise endurance. The results suggest a larger study is worth doing.
