Pressure Features
A
• The interpretation of in-line pressure readings and occlusion alarms is the responsibility of the clinician and is
dependent on the specific application.
• Default downstream occlusion alarm limits for the Pump are configured in the Alaris Editor by profile and by
drug.
In-Line Pressure Monitoring
The infusion set pressure sensing disc enables the measurement of in-line pressure and in conjunction with trending graphs, can
support early clinical assessment and intervention which may assist in reducing the risk of IV complications .
The downstream occlusion alarm limit set through the Auto Pressure or manual functions can assist in optimizing the time to alarm .
A
Despite the benefits provided by early detection of occlusions and reduced time to alarm, the Pump is not designed
to provide protection from or detection of extravasation nor infiltration. Therefore, the clinician, while monitoring
the pressure trend graphs, must also check the infusion site on a regular basis and follow hospital protocols when
IV complications occur.

To check and adjust the downstream occlusion alarm limit press the
e
button . The display
will change to show a 20 minute pressure trend graph displaying the current patient in-line
pressure and the downstream occlusion alarm limit .
The downstream occlusion alarm limit can be adjusted either manually or automatically .
Manual
The downstream occlusion alarm limit can be set manually by pressing the
f
keys to increase or
decrease the pressure alarm limits followed by the
OK
softkey . The new limit will be indicated numerically on the
display screen .
Auto Pressure
The Auto Pressure feature may be used when a stable line pressure has been achieved over a short period of
infusion . If Auto Pressure has been enabled in the editor, the Auto Offset value (XX)mmHg set in the profile will
be used to calculate a new downstream occlusion alarm limit by pressing the
AUTO
softkey followed by the
OK
softkey .
Auto Set Pressure
If the Auto Set Pressure option is enabled, in the editor, the Pump automatically adjusts the downstream
occlusion alarm limit . This occurs once, 15 minutes after the start of the infusion . The Pump automatically adjusts
the downstream occlusion alarm limit to the Auto Set Value (XX) mmHg above the average infusion pressure,
taken from the average of the last 5 minutes of the infusion .
Note:
XX is the
AUTO OFFSET
pressure and is determined by the user . This adjustment,
AUTO OFFSET
value 15-100mmHg, is
configurable by profile within the data set . At pressures up to 100mmHg the
AUTO OFFSET
value is added . For pressures
above 100mmHg the downstream occlusion alarm limit is set to whatever the
AUTO OFFSET
value is as a percentage above
the average infusion line pressure up to the maximum occlusion alarm limit defined within the profile .
