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.
