MPVS-400 Signal Conditioning Hardware
Animal Use Only

MPVS-400 Signal Conditioning Hardware
The MPVS signal conditioning hardware provides digital and/or analog outputs of the time-varying left ventricular pressure and volume signals for data acquisition. The combined pressure and volume signals generate pressure-volume loops that allow calculation and analysis of a wide array of hemodynamic parameters in small animals.

MPVS Signal Conditioning Hardware Features and Benefits

• Combined pressure and volume signal conditioning provides increased ease of use.
• High signal-to-noise ratio allows use of low excitation currents significantly below fibrillation thresholds.
• Built-in Pressure and Relative Volume Unit (RVU) calibration provides quick and easy-to-use calibration reference points.
• Compact and stackable design saves laboratory space.
• Two pressure sensor channels.
• Compatible with six-electrode "selectable segment" catheters.
• Universal power supply.
• High-resolution signal output.
• Fixed signal gain and frequency preserve calibration accuracy and data integrity.
• Compatible with commercially available data acquisition systems.
• Universally compatible with all single- and dual-sensor Millar pressure catheters (with appropriate interface cables).
• Integrated acquisition with digital USB output (MPVS-400 only).
• Additional channel of analog signal input to accommodate peripheral measuring devices, i.e., temperature, flow, pH, etc. (MPVS-400 only).

Data Acquisition System
Integral parts of the complete MPVS package are the data acquisition hardware and software, which are standard with the MPVS-400 system. Key features include:

• Customizable graphical user interface
• Four to eight channels of analog input (stand-alone DAQ hardware only)
• USB output
• Compatible with peripheral measuring devices
• Scrolling strip chart display of pressure and volume waveforms
• Real-time display of P-V loops
• Real-time calculations using raw data (mean, max, min, derivatives, etc.)
• Digital indicators (pressure, volume, heart rate, etc.)
• Multi-point calibration
• Adjustable sampling rates
• Event marking
