The relationship between ventilation and oxygen uptake becomes non-linear above the anaerobic threshold. This threshold can be determined by establishing a ratio of inspired volume and VO2 consumption. Anaerobic threshold also known as lactate threshold (LT) or lactate inflection point (LIP) is the point when lactic acid starts to amass in the blood stream. Use […]
Use the powerful Epoch Analysis data reduction function to reduce large (24-hour) data files to manageable sizes. Analyze both primary signals (such as arterial blood pressure) and derived data (such as Systolic BP). Extract basic measurements from fixed width segments of data. Set “epoch” width to any time interval and key off of scored event […]
The AcqKnowledge® Compliance and Resistance analysis is part of a suite of three automated respiration routines. The other two are Pulmonary Air Flow Analysis and Full Body Plethysmograph Penh. Each routine provides breath-by-breath analysis, event marking and exporting of the values to excel. Compliance and Resistance This analysis requires an air flow signal and a […]
To measure end-tidal CO2 on a breath-by-breath basis, use the AFT20 gas sampling interface kit to connect the CO2100C module directly to the sampling port on the AFT25 facemask. Use AcqKnowledge’s rate detector to find the peak of the cyclic CO2 concentration signal. The running peak value represents the breath-by-breath end-tidal CO2.
Measure the average flow over specified portions of the spirometry curve. The spirometry maneuver requires the subject to inhale to total lung capacity and then exhale forcefully to residual volume. Integrate forced expiratory flow (FEF) to obtain forced expiratory volume (FEV). AcqKnowledge generates the spirometry curve via an X/Y plot of expired volume versus expired […]
The AcqKnowledge® Full Body Plethysmograph – Penh analysis is part of a suite of three automated respiration routines. The other two are Compliance and Resistance and Pulmonary Air Flow. Each routine provides breath-by-breath analysis, event marking and exporting of the values to excel.
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 oxygen consumption measurements nominally incorporate the use of a mixing chamber (AFT15A/B), facemask with non-rebreathing T valve (AFT25) and an air flow transducer (TSD107B). Typically, air flow measurements are performed on the inspiration side of the AFT25. The expiration side is directed to the AFT15, where O2 and CO2 concentrations are monitored using the […]
The Pulmonary Air Flow analysis is part of a suite of three automated respiration routines that are included in AcqKnowledge®. The other two are Compliance and Resistance and Full Body Plethysmograph – Penh. Each routine provides breath-by-breath analysis, event marking and exporting of the values to excel.
The Respiratory Exchange Ratio (RER) is determined by dividing VCO2 produced by VO2 consumed. The measurement is very similar to the setup required for VO2 consumption, except that the produced CO2 flow is integrated simultaneously with the consumed O2 flow. The RER can be presented in real time, with values representing the running average of […]

Discovering and understanding what motivates humans to produce better results has intrigued many researchers. Many researchers have explored the psychophysiological processes that drive our behavior. Here are some recent studies that have used BIOPAC systems to research motivation… Motivation and Pleasure Deficits Undermine the Benefits of Social Affiliation in Psychosis. Blanchard, J. J., Smith, J. […]
