Normal values for FEV1 and FVC suggest a disturbance in respiratory control. A decrease in FEV1/FVC indicates airflow obstruction, whereas a reduction in both FEV1 and FVC and maintenance of FEV1/FVC suggest restrictive lung disease.

Respiratory failure is uncommon in obstructive diseases when FEV1 is >1 L and in restrictive diseases when FVC is >1 L.
