An abnormal FVC could be due to restrictive or obstructive lung disease, and other types of spirometry measurements are required to determine which type of lung disease is present. Physicians should use the Global Initiative for Chronic Obstructive Lung Disease criteria (FEV, Physicians should use the American Thoracic Society criteria (FEV, If an obstructive defect is present, the physician should determine if it is reversible based on the increase in FEV. These include respiratory illnesses such as influenza, measles, chicken pox, pneumonia, and tuberculosis. The first option is to follow the GOLD criteria, which use a cutoff of less than 70%.2 For patients five to 18 years of age, the National Asthma Education and Prevention Program guideline says that a ratio of less than 85% is consistent with an obstructive defect as long as the patient has symptoms consistent with obstructive lung disease.1.
