It requires that the subject make a maximal inspiration to TLC, then make a maximal forced expiratory effort, leaving only the RV. In a normal subject, the FEV 1 /FVC is greater than 0.8; patients with obstructive lung disease, such as asthma or COPD, show a decreased FEV 1 /FVC.

This is the classic definition of restriction as measured by spirometry. (Reduced FVC and FEV 1 values with normal FEV 1 /FVC ratio.) Restriction is further classified as mild, moderate, or severe based on how stiff the lungs have become.
