The
Medfusion3500
infusion pump has numerous alarms built into it. These are triggered by situations, as a means of
warning or advising you something is not functioning within normal parameters.
Alarms / Alerts
Below is a table of the alarms and alerts generated by the pump, including definitions and remedies:
Type
Definition and Remedy
High-priority
A
high-priority alarm
is initiated by either any condition that halts an ongoing infusion, or any pump
system fault, which effect infusion. High-priority alarms are signaled with a flashing red indicator, a
viewing screen backlight that oscillates between bright and dim, and an audible signal. Press the
Alarm
Silence
button to return the viewing screen backlight to bright, and silence the audible alarm for the
programmed alarm silence period.
If the front panel controls are locked when a high-priority alarm occurs, the pump controls
do
unlock.
A
high-priority alarm
that stops delivery during loading dose or bolus will not return to the pause
screen until the alarm is silenced – allowing the user to record the bolus volume delivered
Medium-priority
A
medium-priority alarm
indicates any condition requiring operator intervention but does not halt
infusion. Medium-priority alarms are signaled with a flashing yellow indicator, a viewing screen
backlight that oscillates between bright and dim, and an audible signal. Pressing the
Alarm Silence
button will return the viewing screen backlight to bright, and silence the audible alarm for the
programmed alarm silence period.
If the front panel controls are locked when a medium-priority alarm occurs, the pump controls
do not
unlock.
Low-priority
A
low-priority alarm
indicates any condition not requiring immediate operator intervention.
Low-priority alarms are announced with a continuous yellow indicator, a viewing screen backlight that
oscillates between bright and dim and an audible signal – 2 Medex “Bing-Bongs”, or three international
tones (on 1 sec – off 1 sec, on 1 sec – off 1 sec, on 1 sec – off) signal
If the front panel controls are locked when a low-priority alarm occurs, the pump controls
do not
unlock.
Limit Priority
A
limit-priority alarm
sounds a tone and displays an advisory message onscreen for 3 seconds.
If the front panel controls are locked when a low-priority alarm occurs, the pump controls
do not
unlock.
“Neglected Pump” Alarm
The “
Neglected Pump
” alarm is a medium priority alert. It is simply reminding you to finish what you started. Once
you begin programming any infusion delivery, the pump expects you to continue until setup is complete.
If you “forget” and leave the pump paused too long (30 seconds) on a data entry screen, then the pump initiates a
medium-priority “user callback” alarm.
There are several basic resolutions:
•
Press the
Alarm Silence
button “
” or ANY button to silence the alarm for another 30 seconds.
•
Go to the B
EGIN
I
NFUSION
screen. There the alarm silence interval is at least 2 minutes or longer
−
depending on custom configuration.
•
Press the
Start
button to begin the infusion.
•
You can cancel the infusion and return to the S
ELECT THE
M
ODE
screen, where no alarms sound.
•
You can press & hold the
Power
button and turn off the pump.
