The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty. There is always some air left in the lungs after a maximal exhalation. ...Residual volume is also important for preventing large fluctuations in respiratory gases (O2 and CO2).
