Inductive plethysmography is based on the principle that the respiratory system moves with 2 degrees of freedom.That is,it consists of two moving parts: the rib cage and the abdomen.During inspiration,the rib cage moves outward as the lungs expand in the thorax.Simultaneously,the abdomen is displaced outward by the downward movement of the diaphragm.
