SIGMA Manual Number 41018
Revision AR
Compatible Baxter IV Sets – WARNINGS
The numbers reference the description listing table.
WARNING:
1. Minidrip chambers should not be used for flow rate settings greater
than 200 mL/hr. Doing so may influence flow rate accuracy and cause
nuisance upstream air or upstream occlusion alarms.
2. When using sets with backcheck valves flow rate settings should not
exceed 500 mL/hr. Doing so may influence flow rate accuracy or cause
nuisance upstream air or upstream occlusion alarms. Flow rates above
300 mL/hr may cause fluid to be siphoned from the primary container
during piggyback operation.
3. Partially occluded filters can cause nuisance upstream air, upstream
occlusion or downstream alarms and influence flow rate accuracy.
4. Burettes with closed vents, or shutoff valves will cause upstream
occlusions that may not be detected by the infusion pump.
5. Ball Valve operation may not be detected as an alarm condition when
using the SIGMA Spectrum Pump.
6. Rigid polyethylene lined tubing, as is often used in nitroglycerine sets,
may produce as much as 10 PSI downstream occlusion pressure above
the lower limit of the SIGMA Spectrum Pump specification.
7. Some Sets contain two or more slide clamps. Only the slide clamp on
the pumping section or on the section with the main roller clamp should
be used for pumping operation and clamp detection. Other slide clamps
associated with the set need to be observed and controlled by the user.
8. Blood sets with both clamps closed above the blood filter will cause
upstream occlusions conditions that may not be detected by the pump.

release information.
