Lung Volume Measurement

AcqKnowledge airflow and lung volume data

To record inspired and expired airflow, choose an airflow transducer appropriate to the flow rates expected from the subject and connect the transducer to the DA100C amplifier.

BIOPAC offers a wide variety of air flow transducers to cover applications ranging from high-flow exercise physiology measurements to low-flow animal studies.

Integrate the airflow associated with a maximal inspiration and expiration to obtain the Forced Vital Capacity (FVC) measurement. Determine Tidal Volume (TV) on a breath-by-breath basis by using the AcqKnowledge® rate detector.

To determine the inspiratory capacity (IC), inspiratory reserve volume (IRV) and expiratory reserve volume (ERV) in the same recording, use the Equation Generator to derive them from the FVC and TV measurements.
