MODEL RELEASED. Lung function test. 11 year old boy exhaling into a spirometer at a hospital. The spirometer derives measurements of vital capacity, peak flow rate and forced expiratory volume. Vital capacity is the maximum amount of air that a person can exhale after maximal inhalation. These values can be used to diagnose asthma.
