Alarms
SIGMA Manual Number 41018
Revision AR
■
Do not use effervescent, foamy or frothy solutions.
■
Invert (do not shake) IV bags that need to be mixed.
■
Fill drip chambers half way.
■
Do not load pumped on IV set tubing in the pumping channel or in the air and occlusion
detector areas.
■
Follow prompts and HELP (operating software 6.02.00 and earlier) screens.
■
Use only compatible IV sets as labeled and identified on the SIGMA pump.
■
Keep the tubing channel clean and dry.
■
Avoid empty IV containers by properly setting VTBI values.
■
Plugin pump’s AC power adaptor to maintain battery charge.
■
Using the Low Downstream pressure setting at flow rate setting above 500 mL/Hr may
cause Downstream nuisance alarms that are created by IV set pulsation.
Managing Bolus before Occlusion (Downstream) Release
Managing unintended small bolus releases when clearing downstream occlusions
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” site of the
IV set and eliminate the source of the occlusion.
Battery Warning Levels
The pump provides three warning levels as the battery capacity decreases while operating on battery
power. These levels are:
■
Low Battery
■
Very Low Battery
■
Battery Depleted
There is ample time between the alarms for the pump to be plugged into main power. The trouble-
shooting tutorial also automatically pops up on the pump screen to guide the user through the pro-
cess. See “APPENDIX F - Low / Very Low Battery Tutorial” section, beginning on page 89.
If the pump is not plugged in, the battery continues to slowly discharge even if the pump is turned
off.
Low Battery
When the battery is low, the pump sounds a triple-beep audio alarm every 5 seconds. Press
OK
to
temporarily suspend this alarm.
