Brief Summary
In addition to pharmacological treatment, nonpharmacological treatment with high-flow nasal cannula (HFNC) may play a vital role in the treatment of patients with chronic obstructive pulmonary disease (COPD). The impulse oscillation system (IOS) is new noninvasive technique to measure the impedance of different portions of the airway with higher sensitivity than that of the conventional pulmonary function test (PFT). However, whether IOS is an appropriate technique to evaluate the efficacy of HFNC in improving the impedance of peripheral small airways in patients with COPD is unclear.

Interventions
HFNC was administered using the MyAIRVO 2 device (Fisher \& Paykel Healthcare, Auckland, New Zealand), which provides humidification and high-flow medical gas through an Optiflow NC interface (Fisher \& Paykel Healthcare, Auckland, New Zealand) is administered for 10 min.. NC is administered for 10 min.
Eligibility Criteria
You may qualify if:

- provision of written informed consent.
You may not qualify if:
- severe and unstable comorbidities or active malignancy
- history of obstructive sleep apnoea syndrome
- COPD exacerbation within the 4 weeks prior
- current use of long-term oxygen therapy or noninvasive ventilation or use within the 6 weeks prior
- cognitive impairment or a psychiatric disorder
- pregnancy
