Pressure Baseline
The Pressure Baseline feature, when enabled through the hospital data set profile configuration settings, provides a real-time bar
graph and numeric display of line pressure.
The pressure limit may be reduced if the pressure in the set is high or changing. This results in the pressure limit being lowered
from the selected setting. If this occurs, first try to remove or reduce the downstream pressure. Following that, try to reload the
set, wait 15 to 30 seconds and then perform a Set Pressure Baseline operation. The pressure baseline may need to be set a second
time, after the pressure readings have stabilized.
For dual channel pumps, select the desired channel as necessary. The pressure bar graph is not shown when the split screen
display is active.
For optimal results, set the baseline 15 minutes after starting an infusion. The pressure baseline can be optimised, particularly
at low flow rates (less than 3 ml/h), by resetting the pressure baseline when the readings are negative. Check periodically for
negative readings; for example, when programming VTBI. This allows the pressure baseline to calibrate based on current system
pressure.
1. To place channel on hold, press channel’s
RUN/HOLD
key. (All infusions connected to channel being baselined must be
on hold.)
2. Press
OPTIONS
key.
3. Press
Set Pressure Baseline
soft key.
4. Verify no pressure, due to occlusion or other infusions through a common set, is present in infusion set at this time.
5. For best results, verify set outlet (for example, stopcock) is located at patient’s heart level before continuing with next step.
6. Press
ok
soft key.
7. Verify pressure readout is 0 (zero) mmHg.
8. To start infusion, press
RUN/HOLD
key.

•
To return to the normal screen without setting the baseline, press return soft key.
•
True baseline pressure will be zero or within a few mmHg of zero. If not, and the pressure is
unstable, allow the pressure to drop to the lowest level and then repeat the Set Pressure Baseline
process.
•
The pressure baseline calibration remains in effect until the pump is turned off, the latch is opened,
the set is reloaded, or the set Pressure Baseline function is performed again.
•
Setting the manual baseline overrides the auto baseline until the pump is turned off, the latch is
opened, set is loaded, or another manual baseline is set.
•
Setting a manual Pressure Baseline displays a horizontal real-time bar graph and numeric pressure
readings. The vertical line on the pressure bar graph visually indicates the pressure alarm limit.
