Summary

This study tested whether using a special high-flow oxygen device during exercise training helps people with COPD breathe easier and exercise more. Thirty patients completed 12 rehab sessions, and those using the device could walk at a steeper incline on the treadmill. The approach was safe and well-tolerated, paving the way for a larger study.
