The forced oscillation technique (FOT) is a noninvasive method to measure the mechanical properties of the lung and airways during tidal breathing. In addition to measuring total impedance (resistance and reactance) the Resmon Pro can measure expiratory flow limitation which is a key index of respiratory obstruction. Restech developed patented technology to determine the breath-by-breath presence and severity of expiratory flow limitation (EFL) during quiet breathing. Using the Resmon Pro, a physician can detect the presence, severity and reversibility of EFL, and evaluate the degree of airflow obstruction and shortness-of-breath experienced by the patient.
