Lung Volumes and Capacity

Abstract Lung volumes are vital parameters in clinical medicine, and changes in lung volumes can give useful information about lung function. Lung volumes are measured with a spirometer. Lung capacities are a sum of two or more lung volumes. Furthermore, lung volumes are classified into dynamic and static lung volumes, depending on how the breaths are measured in a spirometer. Slow breaths measure static lung volumes, whereas fast breaths measure dynamic lung volumes . Static lung volumes are residual volume, expiratory reserve volume, inspiratory reserve volume, inspiratory capacity, tidal volume, vital capacity, forced residual capacity, and total lung capacity. Dynamic lung volumes are forced expiratory volume in one second and forced vital capacity.
