Lung or Pulmonary Capacities [Click Here for Sample Questions] Inspiratory Capacity (IC): It is the maximum volume of air that can be inspired from the end-expiration position and thus it is the sum total of tidal volume and inspiratory reserve volume.It is nearly 3500 ml. Lung capacity is a measure of lung volume inferred from the exhaled during the various cycles of breathing. Note that lung volumes are measurable gas-filled spaces in the lung, whereas capacities are combinations of two or more volumes (where the definition of capacity is the measure of the lungs' ability to hold a gas). During respiration, there occurs the movement of air in and out of the pulmonary system. It is about 80 percent of total capacity, or 4.8 liters, because some air remains in your lungs after you exhale. Four types 1. Contraction of the diaphragm causes it to flatten downward. Total Lung Capacity. This results in a decline in the total lung capacity due to a reduction in the residual volume, inspiratory reserve volume and the expiratory reserve volume, sparing the tidal volume.
