The forced vital capacity (FVC) measurement requires the person to exhale the vital capacity (VC) as forcefully and rapidly as possible. The FVC is the most frequently performed pulmonary function test because it provides much information about large and small airway function. It is an effort-dependent test, requiring thorough patient instruction, understanding, and maximal effort. A test is assumed valid if the person can repeat three FVC maneuvers with a variation no greater than 5%.
