Clinical Trial Summary

Early PR is thought to be effective in COPD patients recovering from acute exacerbation, while the effect of HFNC during exercise training in these patients remains unclear. The study may provide evidence of early PR in COPD patients recovering from acute exacerbation.

Description:

We hypothesize that HFNC may increases exercise time in COPD patients recovering from acute exacerbation compare to VM. A randomized, cross-over clinical trial in which either HFNC or VM may be used as an adjunct in 10-MST in random order, respectively, will be performed to compare the endurance time. The physiological effect of HFNC and VM during exercise will also be measured to explore the mechanism.

Related Conditions & MeSH terms

• COPD

Intervention

Device:
• high flow nasal cannula
HFNC provides humidified, heated, oxygen-enriched air at constant concentration with a flow up to 60L/min through a nasal cannula. It washouts the anatomical dead space and decreases the work of breathing.
• Venturi mask
VM is commonly used by COPD patients during exercise training.
