Optimizing the Waveform 14 Monitoring Invasive Pressure

Optimizing the Waveform
♦ In the Setup <Press> menu, select Optimum Scale to let the monitor select the best
minimum and maximum scales for the current wave.
Using the Wave Cursor
When the pressure wave is selected, you can display a cursor in the wave. It appears as a white
horizontal line in the wave. Using the pop-up keys you can move the cursor up or down to the required
position and store the corresponding value. The cursor value can be stored as a systolic, diastolic or
mean pressure value and if the pressure wave is a PAP wave it can also be stored as a PAWP value. The
stored value appears in the trend database as a manually entered value.
To display and position the cursor
1 Select the pressure wave.
2 Select Activate Cursor.
3 Use the pop-up arrow keys to position the cursor.
Using the pop-up keys you can also change the scale or the speed for the wave, freeze the wave or start
a printout or recording.
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 Suppression is configured to 30, 60, or 90 seconds). During artifact suppression,
the monitor shows the INOP message <Pressure label> ARTIFACT, and a question mark is
shown beside the pressure numerics. Pressure alarms and the Pulse NON-PULSATILE INOP are
suppressed during the configured period. The CPP high alarm is not suppressed.
Choosing the Pressure Alarm Source
WARNING Make sure you set alarm limits for the correct label. The alarm limits you set are stored for that
particular label only. Changing the label may change the alarm limits.
You can monitor for alarm conditions in systolic, diastolic and mean pressure, either singly or in
parallel. Only one alarm is given at a time, in this order of priority: mean, systolic, diastolic.
♦ In the Setup <Press> menu, select Alarms from and choose the source.
