38Pulmonary FunctionPulmonary FunctionLung Volume Measurement Q38To record inspired and expired air flow, choose an airflow transducer appropriate to the flow rates expectedfrom the subject and connect the transducer to theDA100C amplifier. BIOPAC offers a wide variety of airflow transducers to cover applications ranging fromhigh-flow exercise physiology measurements to low-flowanimal studies. Integrate the air flow associated with amaximal inspiration and expiration to obtain the ForcedVital Capacity (FVC) measurement. Determine TidalVolume (TV) on a breath-by-breath basis by using thePerform lung volume measurements to analyze respiratoryair flow. Investigate breathing mechanics by examiningpressure/air flow and pressure/volume relationships.Analyze respiratory gas consumption and production inreal time. For metabolic analysis, use the MP System as amoney-saving, flexible alternative to metabolic carts. UseAcqKnowledge to integrate air flow to obtain on-linebreath-by-breath volume. Multiply volume measurementsby gas concentration values to determine amounts of O 2consumed and CO 2 produced. Record airwave pressureand divide by air flow to obtain pulmonary resistance.Divide volume by pressure to derive pulmonary compliance.Features• Lung Volume Measurement• Forced Expiratory Flow & Volume• Volume/Flow Loop Relationships• Automatic Data Reduction• Animal StudiesAcqKnowledge rate detector. To determine the inspiratorycapacity (IC), inspiratory reserve volume (IRV) andexpiratory reserve volume (ERV) in the same recording,use the Equation Generator to derive them from theFCV and TV measurements.Forced Expiratory Flow & VolumeThe forced expiratory flow (FEF) is a measure of theaverage flow over specified portions of the spirometrycurve. The spirometry maneuver requires the subject to
