TROUBLESHOOTING: Data Acquisition Tests
4-10 DASH 2000 Patient Monitor Revision A
2000 412-001
Pace Detect Functions
Do Not Work Properly If the pacemaker detection test results are not correct, as described
above:
¥ Verify the patient simulator is functioning correctly by testing it on a
working monitor,
¥ The acquisition PCB is suspect. Swap a working acquisition PCB into
the monitor and perform these test to verify correct operation.
Invasive Blood
Pressure Functions
The invasive blood pressure (BP) test procedure requires the use of the
following patient simulator: MEI Multifunction Microsimulator, pn.
MARQ1. If use of a different patient simulator is necessary, adjust the
procedure steps/readings accordingly.
Setup BP Connect the BLOOD PRESSURE output of the patient simulator to the
patient connector on the monitor.
Zero-Reference
Properly zero-reference the BP input:
¥ Set the patient simulator BP output to 0 mmHg
¥ Press the ZERO ART softkey in the BP menu.
Generate Dynamic BP
Waveforms Set the patient simulator BP output to WAVE.
Setup the BP scale on the monitor for auto gain:
¥ Select ART from the main menu of the monitor
¥ Select ART SCALE from the ART menu
¥ Select AUTO gain from the ART SCALE menu
Verify Dynamic BP
Results
Once the BP waveforms are setup as described above verify the
following:
¥ The ART BP waveform is noise-free.
¥ BP displayed parameter is within tolerance as indicated in the
following list:
NOTE
These tests are designed for use with a MEI
Multifunction Microsimulator, pn. MARQ1. Accuracy
specifications of the patient simulator in combination
with the monitor (±2% or 1 mmHg, whichever is greater)
is how the parameter values listed above, were derived.
Use of any other manufacturer patient simulator and
associated specifications, can potentially change these
test results.
