Interface with flow meters, fluid-filled balloon-tipped catheters and pressure-tipped catheters to monitor flow rates and left ventricular pressure. Perform a variety of LVP measurements, both on- and off-line. Use the built-in stimulator to pace the heart. Record continuously for short- and long-term studies, or pre-program to record for specific time periods and dosing events. AcqKnowledge® includes automated analysis routines for blood pressure and left ventricular pressure and will display the results as new channels and export them to a spreadsheet for further analysis.

Register NowRecent studies in Psychophysiology, EMG, ECG and PPG measurement utilizing BIOPAC software and hardware: Fight or Flight (Reflex Response Time) “Fight or flight” is a physiological response that occurs due to a perceived threat to survival. It can physiologically be observed through an increase in heart rate, respiratory rate, blood pressure, oxygen availability, and other mechanisms. In […]
HRV, EMG, and EEG studies using BIOPAC hardware and software include: DON’T STRESS Humans encounter various stressful situations everyday at work, home, and school. Such stress when experienced at high degrees and/or for a long duration of time could lead to cardiovascular diseases, cognitive dysfunctions, and psychological disorders. This study examined the validity of a novel physiological measurement […]
