MODEL RELEASED. Lung function test. A young man exhaling into a spirometer at a doctor's office. The spirometer derives measurements of vital capacity, peak flow rate and forced expiratory volume of the lungs. Vital capacity is the maximum amount of air that a person can exhale after maximal inhalation. These values can be used to diagnose asthma or other lung problems. | |
