during maximally forced exhalation (ERV). This is the residual volume (volume of air remaining even after a forced exhalation) of about 1.0-1.5 liters which cannot be measured by spirometry. Volumes that include the residual volume (i.e. functional residual capacity of about 2.5-3.0 liters, and total lung capacity of about 6 liters) can therefore
