CHAPTER 9 System Alarms and
Messages
The Medtronic MiniMed 2007C Implantable Insulin Pump System is
equipped with various alarms and messages that ensure the correct func-
tion of the system.
The Implantable Insulin Pump alarm system will “beep” when certain
conditions occur. The beeps are designed to be audible through the skin
and alert the patient that the Pump needs attention. For severe alarm con-
ditions the Pump will alarm 4 tones each minute for 10 minutes then, 4
double tones each minute for 10 minutes and repeat the pattern. Upon
hearing the alarm, the patient must communicate with the PPC, to deter-
mine the alarm condition. The alarm can be cleared by pressing SEL then
ACT. The following descriptions explain the alarm conditions the system
may encounter.
The PPC has three types of alarms: audible, vibrate and visual alarms.
The chapter will describe for each alarm condition, which screen message
appears and the vibrate or audible alarm associated with it.
Two audible or vibrate alarm types are used:
Alarm Type 1:
If the PPC is set to “vibrate”, the vibrator will be turned on for 3 seconds
every minute for 30 minutes.
If the PPC is set to “audible”, the PPC will beep 6 times every minute for
30 minutes. If the alarm is not cleared in 30 minutes, the PPC will beep 6
alternating tones. The PPC will continue to do so every minute.

Alarm Type 2:
If the PPC is set to “vibrate”, the vibrator will be turned on for 3 seconds
every 30 minutes while the condition exists.
If the PPC is set to “audible”, the PPC will beep 3 times every 30 minutes
while the condition exists.
Some alarms can be cleared by pressing SEL then ACT.
Pump alarms
Alarm feedback
The Alarm Feedback function allows the user to verify the Pump and
Pump alarm are operating normally. Physicians can also use Alarm Feed-
back to measure the time intervals between Pump strokes to verify accu-
rate insulin delivery. When Alarm Feedback is programmed “YES”, the
Pump will beep on each of the first five Pump strokes:
• Following a change in the delivery regimen, for example when
completing a meal Bolus and then changing to a Basal Rate, or at
the start of a bolus.
• After the Alarm Feedback function is programmed “YES.”
Alarm Feedback will stay on until programmed back to “NO.”
Pump low battery
The Implantable Insulin Pump battery is designed to last approximately
ten years during conditions of normal use (see Chapter 11, Technical
Specifications). Battery life may vary somewhat depending upon a user’s
insulin delivery requirements. When battery energy becomes low, a volt-
age sensor in the Pump will trigger the Pump Low Battery Alarm. A
Pump Low Battery Alarm indicates there is approximately eight weeks of
battery energy remaining.
Dmp9196021-011_c.book Page 118 Wednesday, April 3, 2002 5:06 PM
Pump alarms 119
The Pump Low Battery alarm can be cleared and the Pump will continue
to operate normally. However, users should be instructed to report the
alarm immediately to their physician. A Pump replacement or resumption
of conventional insulin therapy should then be scheduled.
Depleted pump battery
When there is no longer sufficient battery energy to power the Pump, the
Pump Low Battery Alarm will cease and insulin delivery will stop. Alter-
nate insulin therapy must be initiated.
System error
The Implantable Insulin Pump has a sophisticated self-monitoring system
that periodically checks for circuit faults. If a fault should occur in the
Pump electronics, insulin delivery will stop. Conventional insulin therapy
must be initiated immediately. Using the PPC Supervisor Mode, the phy-
sician should use the “DOWNLOAD SOFTWARE” feature to reprogram
the Pump from software in the PPC memory. Notify MiniMed immedi-
ately.

Pump self test fail
If during a “SELF TEST” the Pump presents a malfunction, the insulin
delivery will stop. Clear the message by pressing SEL then ACT. Notify
MiniMed immediately.
PPC alarms
The PPC offers a choice of two alarms, audible and vibrate. In addition, a
screen message appears indicating the type of alarm condition that
occurred.
PPC low battery
If the PPC main battery (AA 1.5 volt alkaline) energy is low, the follow-
ing alarm display appears each time a new function is programmed:
Clear this message by pressing SEL and then ACT. While the battery
should have sufficient energy for a few additional programming com-
mands, the battery should be changed as soon as possible. For instruc-
tions on changing the battery, (see Chapter 3, Personal Pump
Communicator).
If “VIBRATOR” is selected, the PPC bat-
tery should last about six weeks during nor-
mal use conditions. If the PPC determines
that the vibrator is causing a low battery
condition, it will automatically change the
Alarm Mo d e to “LOW VOLUME” i n
order to extend battery life.

CHAPTER 10 Troubleshooting Pump
System Under-delivery
Potential under-delivery of insulin by the Medtronic MiniMed 2007C
Implantable Insulin Pump System may result in an increase in daily pro-
grammed insulin usage, difficulty maintaining euglycemia, occasional
hyperglycemia, and problems calculating refill accuracy. This chapter
describes how to diagnose potential Pump System problems that may
cause insulin under-delivery, and offers potential Pump and Catheter solu-
tions to correct for under-delivery.
Diagnostic procedures
When refill procedures reveal the possibility of a Pump System under-
delivery problem, diagnostic procedures must be performed to verify if
there is a problem with either the Pump or Catheter. The Stroke Volume
Measurement Procedure tests Pump function, while the Pressure Mea-
surement Procedure tests Catheter patency. These diagnostic procedures
should be performed according to the steps outlined in Appendix G and
Appendix H, respectively.
Under-delivery caused by backflow
Backflow results in the inverted flow of insulin through the Pump Sys-
tem. Backflow is caused by insulin deposits that compromise valve integ-
rity, and allow the negative reservoir pressure (vacuum) to pull insulin
back into the reservoir. To compensate for this under-delivery, the user
can program appropriate increases in their basal rates and bolus amounts.
Dmp9196021-011_c.book Page 131 Wednesday, April 3, 2002 5:06 PM
Troubleshooting Pump System Under-delivery
132
Backflow conditions are characterized by increases in daily programmed
insulin usage, difficulty in maintaining euglycemia, increasingly negative
refill accuracy and sometimes hyperglycemia. Conform a backflow con-
dition by performing the Stroke Volume Measurement Procedure. Then
rinse the Pump System with NaOH solution to dissolve insulin deposits,
following the Pump Rinse Procedure outlined in Appendix E.
Under-delivery caused by catheter occlusion
Under-delivery caused by Catheter occlusion can occur either abruptly or
gradually. The insulin usage and clinical symptoms are identical to those
of Pump under-delivery. Confirm a Catheter occlusion condition by per-
forming a Pressure Measurement Procedure. Then perform the following
procedures to clear the occlusion:
• First, flush the Catheter by using the Side Port Catheter Flush
Procedure outlined in Appendix F.
• If the Flush Procedure is unsuccessful, replace the Catheter.
Catheter replacement surgery should be performed in a manner similar to
the initial Pump System implantation. PPC initialization will not be nec-
essary. However, after the Catheter replacement, Pump function and
delivery verifications must be performed.
