How is COPD diagnosed?

 

The presence of long term dyspnoea, coughing and mucus production complaints are accepted to be enough for diagnose of COPD but respiratory function test is necessary for exact diagnose. The respiratory function test which can be performed in a few minutes is realised by the patient to exhale after a deep breath into the respiratory apparatus.

Respiratory function test which makes it easy to know about the lung capacity and the stage of the Disease, if any, should be performed at least once a year especially to those over 40 and smoke.
