Test with Marq II or Marq III Simulator
Revision A
Maintenance: Checkout Procedures
5. Set the CO simulator to output injectate temperature (IT) readings,
as found in the following table:
Simulator IT Setting
0.0°C
8.0°C
15.0°C
24.0°C
29.6°C
6. Verify correct IT readings appear on the monitor display, as shown in
the table above.
7. Disconnect the CO cable adaptor from the TEMP/CO connector of the
monitor. This completes the CO tests.
1. Connect the cardiac output cable adapter to the TEMP/CO connector
of the Tram module.
2. Connect the cardiac output adapter to the cardiac output cable
adapter and to the Marq II or to the MarqIII simulator.
3. At the monitor, select MORE MENUS
4. Set up the monitor:
a. Set AUTO MODE: to ON
b. Set INJECT TEMP: to BATH
c. Set SIZE: to 7
d. Set INJECT VOL: to 10CC
e. Set COMPUTATIONAL CONSTANT: to 0.540
5. Set the adapter to 0°.
6. Turn the simulator ON. Select cardiac output menu corresponding to
the injectate temperature. (i.e. menu #92 for 0°, or #95 for 24°)
7. When the monitor screen displays the message, INJECT WHEN
READY, press Enter on the simulator.
8. When computing is complete, the CO reading should be
approximately 37°C at 5 liters of blood per minute ± 5%.
9. Repeat this test with the adapter set to 24° and the
COMPUTATIONAL CONSTANT: set to 0.595.
10. The output should be the same.
