Prognosis

Home » Diseases » COPD » Prognosis

The overall prognosis for a patient with COPD depends on the severity of lung disease and whether the patient continues to smoke. An FEV1 (forced expiratory volume after 1 second) greater than 50% predicted carries a very good prognosis, with the survival of these patients being only slightly less than patients without COPD. Patients with an FEV1 less than 0.75 L (very severe obstruction, less than 30% predicted), have a 1-year mortality rate of 30% and a 10-year mortality rate of 95%. At any level of lung impairment, prognosis improves when the patient quits smoking.
