To assess spirometry results, compare the patient's measured values of FEV1 (Forced Expiratory Volume in one second), FVC (Forced Vital Capacity), and the FEV1/FVC ratio to predicted normal values based on age, sex, height, and ethnicity. An FEV1/FVC ratio below 70% typically indicates obstructive lung disease, while a reduced FVC with a normal or high FEV1/FVC ratio suggests restrictive lung disease. Always consider clinical context and reference guidelines for a comprehensive evaluation.
