Operating Precautions
Operating Precautions
Disposable Infusion Sets
To ensure correct and accurate operation, only use CareFusion dedicated infusion sets described in this
Directions For Use.
It is recommended that infusion sets are changed according to the instructions in the 'Changing the Infusion
Set' section. 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.
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 IVAC® 598 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.
Using Collapsible Bags, Glass Bottles and Semi Rigid Containers
It is recommended that the air vent be opened on the IVAC® 598 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 Collapsible 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.
Operating Environment
When using any infusion pump in conjunction with other pumps or devices requiring vascular access,
extra care is advised. Adverse delivery of medication or fluids can be caused by the substantial variation in
pressures created within the fluid channels of such pumps. Typical examples of those pumps are used during
dialysis, bypass or cardiac assist applications.
The Pump is suitable for use in hospital and clinical environments other than domestic establishments and
those directly connected to the public single phase AC mains power supply network that supplies buildings
used for domestic purposes. However, it may be used in domestic establishments under the supervision of
medical professionals with additional necessary appropriate measures. (Consult Technical Service Manual,
appropriately trained technical personnel or CareFusion for further information). Mains power quality should
be that of a typical commercial or hospital environment.
The Pump is not intended to be used in the presence of a flammable anaesthetic mixture with air or oxygen
or nitrous oxide.
Operating Pressure
The pumping pressure alarm system is not designed to provide protection against, or detection of,
extravasation or tissuing 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.
