CHRONIC OBSTRUCTIVE PULMONARY DISEASE - CRITERIA FOR DIAGNOSIS

Abstract

The tests used to diagnose chronic obstructive pulmonary disease (COPD) can be divided into three groups. These a functional examination, imaging examinations and other tests helpful in the assessment of the disease's advancement. The basic test for suspicion of COPD is spirometry. It can be used to assess lung function noninvasively and quickly. Spirometry allows evaluation of volume components and components of air flow velocity in the lungs. Blood gas measurement is also helpful. Imaging examinations used in the diagnosis of COPD include chest radiograph and computed tomography. The results of these studies show above all the advancement of emphysema and the location of airspace. Additional tests to help diagnose COPD include electrocardiography, echocardiography, morphology and sputum culture. Their results, even though they do not give a clear diagnosis of COPD, can facilitate to make a correct diagnosis.
