Overview
Other Diagnostic Studies
Spirometry
Obstruction can be measured using spirometry. A decreased FEV1/VC ratio (versus the normal of about 80%) is indicative of an airway obstruction, as the normal amount of air can no longer be exhaled in the first second of expiration. An airway restriction would not produce a reduced FEV1/VC ratio, would produce a reduced vital capacity.
