Preventing Nuisance Alarms
Check the following items to prevent nuisance alarms:
■
Remove all air from IV sets and Y sites.
■
Do not administer extremely cold or hot solutions. Warm solutions to room temperature
before use to help prevent nuisance upstream occlusion or air-in-line alarms caused by out-
gassing of micro bubbles.
Upstream Occlusion
Suspension
If a drug has been checked as an Effervescent Drug in the MDL
(Drug Configurations / Upstream Occlusion Alarm), once flow
has been confirmed (check flow display), if the operator
considers the occlusion alarm to be a nuisance, they may choose
to suspend the alarm until the next
STOP
key press.
After
YES
is pressed to check flow, the operator may select to
suspend the upstream occlusion alarm temporarily on the
Occlusion Alarm screen. If
YES
is selected, the upstream
occlusion alarm “OFF” icon displays on the
RUN
screen. With
the next
STOP
key press, or after the door is opened, the alarm
will again become enabled.
This alarm applies to operating software versions 6.03.01 and
later.
Very Low Battery
Less than ½ of the low battery capacity remains. The AC Power
Adaptor should be plugged in immediately. The tutorial to
check the AC Power Adaptor will automatically begin (see
“APPENDIX F - Low / Very Low Battery Tutorial” section,
beginning on page 89).
