NCT01553812

Brief Summary

The study hypothesize that parameters of new function machine---'forced oscillation technique' (FOT) can correlate well with the conventional lung function data for measurement of airway resistance and airtrapping in elderly COPD patients.

Sampling MethodNon-Probability Sample
Study Population

COPD patients from both 'in-patient' and 'outpatient clinic' in Kwong Wah Hospital, Hong Kong, China

You may qualify if:

  • COPD patients with previous lung function tests confirming irreversible obstructive pattern

You may not qualify if:

  • Lung function test failed to show any obstructive pattern
  • Paitents with co-existing pulmonary diseases including asthma, interstitial lung diseases, lung malignancy etc.
  • Patients with active infectious diseases like tuberculosis
