The purpose of the CI-3 module/cable is:
• To facilitate the medSim 300B connection to the cardiac output measurement
device under test.
• To simulate the injectate temperature (IT) thermistor at 2 °C.
Of the two connectors on the CI-3 module/cable, the smaller 3-pin connector is for
catheter blood temperature (BT) and is standard on most monitors.
Note
This 3-pin catheter BT connector is compatible with the standard Baxter
(Edwards) BT catheter and similar catheters available from other
manufacturers such as Viggo-SpectraMed and Abbott (Sorenson).
The larger 4-pin connector supplies the simulated injectate temperature.
The 10-turn 100 ke potentiometer enables adjustment of the injectate temperature to
2 °C.
Although this 100 ke range of resistance has proven adequate to simulate the 2 °C
temperature for most brands of cardiac output measurement devices, the 4-pin IT
thermistor connector is not standard on all monitors. Therefore, a general purpose
connector that can be wired to the equipment under test (EUT) injectate cable is also
supplied.
Note
An illustration of the assembly and wiring of the general purpose connector
is located at the end of this chapter. Please note that the injectate
temperature thermistor will have to be cut off the EUT cable to install the
general purpose connector. In addition, an EUT cardiac output cable
modified for testing purposes should not be used for any clinical
application. If the EUT cardiac output cable incorporates an
interconnection (or plug-in) for the injectate temperature bath probe
assembly, modify that plug-in cable only.
Note
To facilitate the interface of the medSim 300B patient simulator to selected
brands of cardiac output measurement devices, optional adapter cables are
offered by Fluke Biomedical.
• To evaluate Hewlett Packard Merlin systems, a cardiac output
adapter and a temperature adapter are required.
• Gould/SpectraMed Models SP1445 and SP1465 cardiac output
devices each require a specific adapter.
See the current Fluke Biomedical Price List for availability, part number
information and price.
For cardiac output simulation, connect the medSim 300B to the EUT using the supplied
CI-3 module/cable and, if necessary, the general purpose connector.
Set up the EUT for the following simulated parameters:
Catheter Size:
7 F
Injectate Volume: 10 cc
Computational Constant: 0.542
