Revision B Operator’s Manual
Troubleshooting Alarm Causes
Check the following items to prevent alarms:
■ Use only compatible IV sets as labeled and identified on the SIGMA Spectrum Infusion Pump.
See “Compatible IV Sets” on page 123.
■ Remove all air from IV sets. Slowly prime the IV line while inverting and tapping air from all Y
injection sites and backcheck valves.
■ Do not administer extremely cold or hot solutions.
■ Warm solutions to room temperature before use to help prevent upstream occlusion or
air in line alarms caused by out-gassing of micro bubbles.
■ Effervescent, foamy, or frothy solutions can result in upstream occlusion alarms.
■ Invert (do not shake) IV bags that need to be mixed.
■ Fill drip chambers half way.
■ Do not reload pumped-on tubing (the tubing segment previously used in the pumping channel)
into the pumping channel.
■ Keep the pumping channel clean, dry and free of dirt and debris.
■ Avoid empty IV containers by properly setting VTBI values.
■ Plug in the Pump’s AC Power Adaptor to maintain battery charge.
■ Use the medium or high DS Pressure Limit (Downstream Occlusion Pressure Limit) setting at
flow rate settings above 500 mL/hr to avoid downstream occlusion alarms that are created by
IV set pulsation.
Managing Bolus before Occlusion (Downstream)
Release
When a downstream occlusion alarm occurs, pressure and a small volume of <0.98 mL of fluid
(the “bolus”) builds up between the Pump and the point of occlusion. When it might be harmful to
infuse the bolus into the patient, simultaneously withdraw 0.9 mL of fluid from the lower Y injection
site of the IV set and eliminate the source of the occlusion.
Value Entry Timeout Displays when entered value is not confirmed within ten seconds of entering value.
The previous value is restored.
1. Re-enter desired value.
2. Press OK to confirm entered value.
VERY LOW BATTERY Displays when less than half of the low battery capacity remains.
1. Plug the AC Power Adaptor in immediately.
2. Follow the tutorial to check the AC Power Adaptor will automatically begin. See
Appendix F: “Low / Very Low Battery Alarm Instructions” on page 157.
