Hardware Connections
Front Panel
1.
Lighted Power Indicator - The green indicator will be lit when the system is receiving
power and turned on.
2.
Cuvette Input – Rho Calibration Cuvette connects to the MPVS
Ultra
and provides
resistivity value for volume calibration (color-coded gray)
3.
ECG Input – External ECG electrodes can be connected to the MPVS
Ultra
(input color-
coded green) and the signal can be displayed real-time
4.
Pressure-Only Catheter Input (P2) – A second, pressure-only, Mikro-Tip
®
catheter can be
connected to the MPVS
Ultra
. The input to the second pressure channel can be through
the P2 connector (color-coded blue) or the P-V connector (color-coded black).
5.
Pressure-Volume Catheter Input (P-V) – The MPVS
Ultra
connects to all of Millar’s
Pressure-Volume catheters including the
Ultra
-miniature single segment P-V catheters
and the Multi-Segment P-V catheters with the appropriate cables. The system can accept
inputs from P-V transducers with one or two pressure sensors. When connecting to a
three-connector, dual-pressure P-V transducer, be sure to follow the labeling on the
connectors to ensure that the pressure sensor inputs are not swapped.
6.
Analog Pressure Outputs - The MPVS
Ultra
provides analog output for both pressure
channels at individual BNC connectors. The pressure signals (P1 and P2) are scaled to
1V/100mmHg.
7.
Analog Composite Volume Output – The MPVS
Ultra
provides an analog composite
volume channel that outputs the analog sum of the individual volume segments. This
signal is useful for viewing real-time P-V loops in the data acquisition software. The
volume signal compliance can be altered with the gain adjust function in the MPVS
Ultra
Control Interface.
8.
Analog Volume Segment Outputs – The MPVS
Ultra
provides an analog output for a
maximum of seven volume segments which can be displayed in real-time on a computer
through the data acquisition system. The pressure-volume analysis software PVAN
Ultra
will use these individual segments. The volume signal compliance can be altered with
the gain adjust function in the MPVS
Ultra
Control Interface.
