The residual volume (RV) is the volume remaining in the lungs after expelling as much air from your lungs as possible. Residual Volume (RV) is the amount of air an individual never physiologically expires. Functional residual capacity (FRC) cannot be estimated through spirometry, since it includes the residual volume (RV). At functional residual capacity, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles. Functional residual capacity (FRC) is the sum of Expiratory Reserve Volume (ERV) and Residual Volume (RV) and measures approximately 2400 mL in an average sized person with no lung pathology. However, there is still air left in your lungs 1.

This test allows the health care provider to estimate how well the lungs move oxygen from the air into the bloodstream.Ī.D.A.M., Inc. The difference in the amount of gas inhaled and exhaled measures how effectively gas travels from the lungs into the blood. The concentration of the gas in the air you breathe out is measured. To measure diffusion capacity, you breathe a harmless gas, called a tracer gas, for a very short time, often for only one breath. The concentration of the gas in a chamber attached to the tube is measured to estimate the lung volume.
