ABSTRACT
The volume of air inhaled or exhaled during each respiratory cycle is the tidal volume (VT). The amount of air that can be inspired maximally from the end-inspiratory level during tidal breathing is termed the inspiratory reserve volume (IRV). The volume of air that can be expired maximally from the end-expiratory level during tidal breathing is the expiratory reserve volume (ERV). At rest, the IRV and ERV are usually in the range
