Clinical Presentation And Diagnosis Diagnosis

A suspected diagnosis of COPD should be based on the patient's symptoms and/or history of exposure to risk factors. Spirometry is required to confirm the diagnosis. The presence of a postbronchodilator FEV1/FVC ratio less than 70% (the ratio of forced expiratory volume in 1 second [FEV1 to forced vital capacity [FVC]) confirms the presence of airflow limitation that is not fully reversible. 1 Spirometry results can further be used to classify COPD severity (Table 15-1). Full pulmonary function tests (PFTs) with lung volumes and diffusion capacity and arterial blood gases (ABGs) are not necessary to establish the diagnosis or severity of COPD.
