Operating Precautions
Operating Precautions
Infusion Sets
• To ensure correct and accurate operation, only use BD single use infusion sets described in the 'Compatible
Dedicated 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 800 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 .
• BD recommends the use of the IVAC® Model 180 Flow Sensor when using sets without anti-siphon valves or
the mandatory use of the IVAC® Model 180 Flow Sensor whenever the Pump set detection mode is disabled .
The flow sensor automatically monitors the infusion flow rate through the drip chamber and will cause the
Pump to alarm if a significant deviation from the infusion rate occurs . The flow sensor will detect empty
containers .
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 .
• Alarm tone settings are preserved in the case of 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 .
