13 Monitoring Invasive Pressure

Adjusting the Calibration Factor
Each time you use a reusable transducer, compare the calibration factor written on your transducer
with the calibration factor shown on the monitor. To ensure accurate measurement, they must be the
same.
1 In the Setup <Press Label> menu, select Cal. Factor.
If the value here does not match that on the transducer, select the corresponding value from the
list, in accordance with your hospital's procedure.
2 To confirm you want to use the new calibration factor, select the Confirm pop-up key.
Displaying a Mean Pressure Value Only
Use this when you want to see only the mean pressure.
In the pressure's setup menu, select
Mean only. Toggle between On to display mean pressure value only,
and
Off to display all pressure values (systolic, diastolic and mean).
Changing the Pressure Wave Scale
1 Select the label of the pressure wave whose scale you want to set to enter the Setup <Press Label>
menu.
2 In the Setup <Press Label> menu, (for example ABP) select Scale.
3 Select a value from the pop-up list:
– a positive value sets the top gridline. The bottom gridline is set at zero.
– a negative value sets the bottom gridline. The middle gridline is set at zero.
Optimizing the Waveform
In the Setup <Press Label> menu, select Optimum Scale to let the monitor select the best minimum and
maximum scales for the current wave.
Non-Physiological Artifact Suppression
Some clinical procedures may affect blood pressure, for example, a flush procedure or a blood sample.
Your monitor may be configured to suppress these non-physiological artifacts for a specified duration
(
Artifact Suppr. is configured to 30 sec, 60 sec, or 90 sec). During artifact suppression, the monitor
shows the INOP message
<Press Label> Artifact, and a question mark is shown beside the pressure
numerics. Pressure alarms and the
<Press Label> No Pulse INOP are suppressed during the configured
period. The CPP alarms are not suppressed.
<Press Label> can't cal.; unstable

Make sure there are no disturbances to the transducer, and
repeat the calibration.
<Press Label> can't calibr.;do zero

No valid zero. Zero the transducer.
