Operating Precautions
Infusion Sets
•
To ensure correct and accurate operation, only use CareFusion single use infusion sets described in the
'Compatible Infusion Sets' section of this Directions for Use. Use an infusion set with an anti-siphon valve
whenever possible. The anti-siphon valve prevents free flow from occurring if an infusion set is incorrectly
loaded or removed from the pump.
•
It is recommended that Infusion sets are changed in accordance with the Directions for Use.
Carefully read the Directions For Use supplied with the Infusion set prior to use. Use of non-specified Infusion
sets may impair the operation of the pump and the accuracy of the infusion.
•
When combining several apparatus and/or instruments with Infusion sets and other tubing, for example via
a 3-way tap or multiple Infusion, the performance of the pump may be affected and should be monitored
closely.
j
•
Uncontrolled flow may result if the Infusion set is not properly isolated from the patient i.e. closing a tap in
the set or activating an in-line clamp/roller clamp.
•
The Infusion set may be fitted with an in-line clamp, which can be used to occlude tubing in case it is
required to stop fluid flow.
•
The Alaris® GW Volumetric Pump is a positive pressure pump, which should use Infusion sets fitted with Luer
lock fittings or equivalent locking connectors.
•
To infuse from a burette, close the roller clamp above the burette and open the clamp on the vent on top of
the burette.
•
Discard Infusion set if the packaging is not intact or the protector cap is detached. Ensure sets are not kinked
as this may occlude the tubing.
Mounting the Pump
^
•
The fluid height in the container must not be more than 1 metre above the patients heart.
%;
•
Do not mount the pump in a vertical position with the AC power inlet pointing upwards as this could affect
electrical safety, in the event of a fluid spill over the pump.
Operating Pressure
•
The pumping pressure alarm system is not designed to provide protection against, or detection of, IV
complications which can occur.
Alarm Conditions
•
Several alarm conditions detected by this pump will stop the infusion and generate visual and audible
$
alarms. Users must perform regular checks to ensure that the infusion is progressing correctly and no alarms
are operating.
Using Collapsable bags, Glass Bottles & Semi Rigid containers
•
It is recommended that the air vent be opened on the Alaris® GW Volumetric Pump set if using glass bottles
or semi-rigid containers, to reduce the partial vacuum formed as the fluid is infused from the container.
This action will ensure the pump can maintain volumetric accuracy whilst the container empties. The action
of opening the air vent for semi-rigid containers should take place after the spiking of the container and
priming of the drip chamber.
Steps for the Collapsable bags
Follow steps 1 to 3 as shown for
the semi-rigid containers, however
do not open vent as in step 4, but
prime the set as per step 5. Ensure
the bag outlet is fully pierced
before filling the drip chamber.
