Clinical Trial Summary

Although non-invasive positive pressure ventilation (NPPV) shows the good curative effect of treating the patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), some patients do not tolerate NPPV or do not benefit from it. High-flow nasal cannula (HFNC) is well tolerated and may be used to patients with AECOPD who are intolerant to NPPV treatment. This study is to evaluate the physiological effect of HFNC and compare it with NPPV.
