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.
• Uncontrolled flow may result if the Infusion set is not properly isolated from the patient i.e. closing a tap in
j
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
Alaris® GW Volumetric Pumps
Operating Precautions
^
%;
$
• 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.

Alaris® GW Volumetric Pumps
Operating Precautions
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 local vascular system by such pumps. Typical examples of those pumps are used
during dialysis, bypass or cardiac assist applications.
• This 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 qualified service personnel or CareFusion for further information).
• This pump is not intended to be used in the presence of a flammable anaesthetic mixture with air or oxygen
or nitrous oxide.
Electromagnetic Compatibility and Interference
• This pump is protected against the effects of external interference, including high energy radio frequency
emissions, magnetic fields and electrostatic discharge (for example, as generated by electrosurgical and
cauterising equipment, large motors, portable radios, cellular telephones etc.) and is designed to remain safe
when unreasonable levels of interference are encountered.
• Therapeutic Radiation Equipment: Do not use the pump in the vicinity of any Therapeutic Radiation
Equipment. Levels of radiation generated by the radiation therapy equipment such as Linear Accelerator,
may severely affect functioning of the pump. Please consult manufacturer’s recommendations for safe
distance and other precautionary requirements. For further information, please contact your local CareFusion
representative.
• Magnetic Resonance Imaging (MRI): The pump contains ferromagnetic materials which are susceptible to
interference with magnetic field generated by the MRI devices. Therefore, the pump is not considered an MRI
compatible pump as such. If use of the pump within an MRI environment is unavoidable, then CareFusion
highly recommends securing the pump at a safe distance from the magnetic field outside the identified
Controlled Access Area in order to evade any magnetic interference to the pump; or MRI image distortion.
This safe distance should be established in accordance with the manufacturers’ recommendations regarding
electromagnetic interference (EMI). For further information, please refer to the product technical service
manual (TSM). Alternatively, contact your local CareFusion representative for further guidance.
• Accessories: Do not use any non-recommended accessory with the pump. The pump is tested and compliant
with the relevant EMC claims only with the recommended accessories. Use of any accessory, transducer
or cable other than those specified by CareFusion may result in increased emissions or decreased pump
immunity.
• In some circumstances the pump may be affected by an electrostatic discharge through air at levels close
to or above 15kv; or by radio frequency radiation close to or above 10v/m. If the pump is affected by this
external interference the pump will remain in a safe mode; the pump will duly stop the infusion and alert
the user by generating a combination of visual and audible alarms. Should any encountered alarm condition
persist even after user intervention, it is recommended to replace that particular pump and quarantine the
pump for the attention of appropriately trained qualified service personnel.
• This pump is a CISPR 11 Group 1 Class B device and uses RF energy only for its internal function in the normal
product offering. Therefore, its RF emissions are very low and are not likely to cause any interference with the
nearby electronic equipment. However, this pump emits a certain level of electromagnetic radiation which
is within the levels specified by IEC/EN60601-1-2 and IEC/EN60601-2-24. If the pump interacts with other
equipment, measures should be taken to minimise the effects, for instance by repositioning or relocation.
• For further information on electromagnetic compatibility, please consult Technical Service Manual,
1000SM00006.

a button is released during the countdown the pump will not power down and it will return to its previous state.
If the pump alarms, segments / indicators do not light up correctly or 2 audible sounds are not heard, then the pump
must be powered down immediately, and qualified service personnel contacted. If transportation to an engineer is
necessary, it is recommended to use the original protective packaging.
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. Infusion sets with an anti-siphon valve
can only be primed when loaded in the pump.
When using infusion sets without an anti-siphon valve eg. 273-004, 273-007 and 273-008, the infusion set can be
primed without using the pump. Use of a flow sensor is recommended when using an infusion set without an antisiphon valve. The flow sensor will cause the pump to alarm if a significant deviation from the set infusion rate occurs.
Getting Started
1. Ensure the pump is switched on and in-line clamp is open.
2. Load the Infusion set (see 'Loading the Infusion Set').

The prime (
E) volume delivered will not be subtracted from the VTBI, or added to the total volume infused.
Automatic Set Detection
The pump automatically tests that a compatible CareFusion Infusion set has been loaded correctly (refer to 'Compatible Infusion Sets'
section of this DFU). The test will occur at the start of the first infusion after the pump is switched on or after the door has been opened;
the pump will run in reverse for 10 seconds and then forward for 10 seconds, the test takes a maximum of 20 seconds to complete.
During this operation the clinician may observe a blood return that will be more evident if using a small catheter.
If the pump fails to detect a correct CareFusion Infusion set or detects a possible set misload, then the pump will alarm and display
