A system and method for determining FRC, TGV, TLC and RV includes a hand-held unit with a shutter assembly designed to minimize measured air displacement due to shuttering. Measurements of flow and pressure are used to derive the lung parameters.

System and methods for the measurement of lung volumes

A method for determining a pulmonary volume change includes: receiving a respiration event from a subject in an airflow chamber; interrupting the respiration event by an occlusion of the airflow chamber initiated at a first time instant and terminated at a second time instant subsequent to the first time instant; taking a plurality of measurements of airflow rate through the airflow chamber between the second time instant and a third time instant subsequent to the second time instant; and determining a pulmonary volume change substantially equal to a reduction of a pulmonary air volume by a pulmonary response air volume and a normal air volume, wherein the pulmonary volume change is related to a change in density of air in the airflow chamber.
