WARNING
Air Bubbles.
Failure to prime/remove all air bubbles from backcheck valves in
primary sets may cause the valve to malfunction, resulting in
secondary fluid flow back up into the primary container.
WARNING
IV Set Loading.
Load tubing directly from the slide clamp to the top of the tubing
channel. Confirm the tubing from the IV container enters the back
of the slide clamp and exits the front of the slide clamp prior to
loading the tubing section into the Pump channel.
Improper or reverse IV set loading will result in a no flow condition
to the patient, as well as possible back flow of blood from the IV set
into the IV tubing and/or occlusion/air in line alarms.
Follow the Direction of Flow diagram and screen prompts to load
IV set tubing correctly.
WARNING
Do Not Allow Uncontrolled Gravity Flow.
Before loading a primed IV set, ensure the roller clamp below the
Pump is in the closed position.
To open the Pump door, the IV set’s slide clamp must first be
closed (thus providing “set-based anti-free flow” protection).
Do not open the slide clamp when the door is open or during and
after IV set unloading. This can cause dangerous, uncontrolled
free flow to occur.
During IV container changes, always close the set’s roller clamp.
When the set is in the Pump and the door is closed, the slide
clamp can safely be opened. If gravity flow is to be used, the Pump
door will be open or the set will be outside the Pump. Verify gravity
flow is maintained at the intended rate whenever the Pump door is
open and when the set is outside of the Pump.
WARNING
Bolus.
When an administration set is loaded, the door is closed and the slide
clamp is removed, a fluid bolus will occur (maximum of 0.1 mL).
WARNING
Proper Venting Required.
Upstream occlusions caused by improperly vented glass bottles or
burettes may not be detected because of the very slow-building
vacuums resulting from these situations.
WARNING
Time to Upstream Occlusion at Lower Flow Rates.
When infusing at flow rates below 5 mL/hr, the Pump may take an
extended period of time to detect an upstream occlusion and sound
an alarm.
Ensure the following:
