Vital capacity is the maximum volume of air that a person can inspire after forcefully and maximally exhaling, while residual volume is the volume of air remaining in the lungs after such a forceful exhalation. Pulmonary function testing generally includes measurements of airflow, lung volume, and diffusion capacity, or the ability of the lungs to move oxygen from the air into the bloodstream and to move carbon dioxide from the bloodstream into the lungs.
