WebThe tidal volume ( VT, TV) is the volume of gas which is inspired or expired during a respiratory cycle; although listed under static lung volumes, it is a dynamic lung volume, which varies with the level of physical activity. It is commonly measured at the mouth and varies with measuring conditions (rest, exercise, posture). WebThe spirometer—a device that measures movement of air—will provide us with a recording of a range of lung volumes. Residual Volume (RV) is the air that is left in the lungs after a maximal exhalation, so RV will be estimated today as 1.2 Liters. Capacities, such as Total Lung Capacity (TLC), refer to two or more volumes combined (Figure 7.1).
