Overview
BDDF00558 Issue 5 5/72
Overview
Introduction
The BD Alaris™ neXus GP Volumetric Pump is a small lightweight volumetric infusion pump that provides accurate and
reliable infusions over a range of rates.
The BD Alaris™ neXus GP Volumetric Pump can be programmed to deliver fluids utilising rate, volume over time, dose rate
calculation, and pre-programmed drug dosing protocols containing drug concentration values, and Guardrails™ dosing
safety limits.
The BD Alaris™ neXus Editor software is a medical device accessory which allows the hospital to develop a best-practice
data set of IV medication dosing guidelines for patients-specific care areas referred to as profiles. Each profile contains a
specific library of drugs, as well as an appropriate Pump configuration.
A profile also contains Guardrails™ Soft and Hard Limits, based on clinical requirements. Soft Limits may be overridden
during infusion programming and Hard Limits may not be overridden.
The BD Alaris™ neXus GP Volumetric Pump with a data set loaded, provides automatic alerts when a dosing limit, bolus
limit or weight limit has been exceeded. These safety alerts are provided without the need for the Pump to be connected
to a PC or network.
The hospital defined data set is developed and approved through pharmacy and clinical input, and then transferred into
the Pump by Qualified Service Personnel, either manually using BD Alaris™ neXus Transfer Tool or automatically via BD
Alaris™ Communication Engine.
The BD Alaris™ neXus GP Volumetric Pump can connect to the BD Alaris™ Communication Engine, if one is deployed at
the medical facility. When connected, either by docking to a connected Alaris™ Gateway Workstation or via hospital Wi-Fi,
Pump infusion data, logs and configuration information will be automatically collected.
Note: Any serious incident that occurs in relation to this Pump should be reported to the manufacturer, and to the
relevant local regulatory authority.

BDDF00558 Issue 5 18/72
Operating Precautions
Infusion Sets
• To ensure correct and accurate operation, only use BD single use 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
aected 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.
• BD infusion sets are fitted with an in-line clamp, which can be used to occlude tubing in case
it is required to stop fluid flow.
• The 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 Pump sets 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 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.
Note: Ensure that the air vent is
closed prior to filling the drip
chamber.

Operating Environment
• Intended environments include general wards, critical and intensive care, operating rooms,
accident and emergency rooms. The Pump may be used in an ambulance environment.
Ensure that the Pump is appropriately attached using the provided pole clamp. The Pump
is designed to withstand possible bumps and vibrations whilst being used in an ambulance,
complying with the standard EN 1789. If the Pump is dropped or experiences any severe
physical disturbances, arrange a thorough inspection by Qualified Service Personnel as soon
as is practically possible.
• The Pump may also be used outside the ambulance as long as the temperature is within the
specified range as stated in the ‘Specifications’ section and on the Pump label.
• 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 that have access to single phase AC power supply.
• This 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.
• Alarm tone settings are preserved in the case of a power loss, however some system faults
will result in loss of alarm settings. The new alarm tone settings will be stored when powering
down from tech mode after a change. The settings will be lost if a cold-start is performed, but
should be saved for faults that don’t require a cold start.
