Invasive Blood
Pressure Functions The invasive blood pressure (BP) test procedure requires the use of the
following patient simulator: Multifunction Microsimulator
(pn. MARQII). If you need to use a different patient simulator, adjust the
procedure steps/readings accordingly.
Setup BP1 Connect the BLOOD PRESSURE 1 output of the patient simulator to the
P1 patient connector on the side panel of the monitor.
Setup BP2 Connect the BLOOD PRESSURE 2 output of the patient simulator to the
P2 patient connector on the side panel of the monitor.
Zero-Reference Both
BP’s
Properly zero-reference each BP input:
• Set the patient simulator BP output to 0 mmHg
• Press the ZERO ALL front panel control on the monitor.
Generate Dynamic BP
Waveforms Set the patient simulator BP output to WAVE.
Setup the BP scales on the monitor for auto gain:
• Select AR1 from the main menu of the monitor
• Select ART SCALES from the AR1 menu
• Select AUTO gain from the ART SCALES menu
• Return to the main menu of the monitor and setup auto gain for the
PA2 waveform as you did for AR1.
Verify Dynamic BP
Results Once the BP waveforms are setup as described above verify the following:
• Both the AR1 and PA2 BP waveforms are noise-free, as shown in the
figure at the left.
• BP displayed parameters are within tolerance as indicated in the
following list:
NOTE: These tests are designed for use with a Multifunction
Microsimulator, pn. MARQII. 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.
