Tidal volume represents a normal volume of air that is inhaled and exhaled during relaxed breathing. This value is usually around 500 mL.
Total Lung Capacity (TLC) represents the total amount of air that the lungs can hold at a given time.
Inspiratory Reserve Volume (IRV) represents the amount of air that can be inhaled, or inspired, in excess of the normal amount of inhaled air (tidal volume).
Residual Volume (RV) represents the amount of air remaining in the lungs after forced exhalation. This volume always remains in the lungs in order to prevent lung collapse.
Use the diagram below as a visual reference for the different volumes associated with a breath.
