Revision B Operator’s Manual
UPSTREAM
OCCLUSION
Displays when the Pump detects an occlusion above the Pump.
To eliminate the occlusion or flow restriction:
1. Check and open any of the following:
Closed slide clamp
Closed burette vent
Closed vent on drip chambers with rigid or semi rigid containers
2. Check and eliminate kinked or collapsed IV tubing outside the Pump.
3. Verify the occlusion has been eliminated.
4. Press RUN to start the infusion.
5. Verify the drop rate is consistent with the programmed rate.
NOTE: If unable to locate an occlusion, see “Troubleshooting Alarm Causes” on
page 114.
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:
All clamps are open.
There are no kinks or collapses in the
tubing outside of the Pump.
Drops are flowing in the drip chamber.
Note, at very low rates, it may take
several minutes to see drops.
Vents are open (if applicable).
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.
