117CHAPTER 9 System Alarms and Messages The Medtronic MiniMed 2007C Implantable Insulin Pump System isequipped with various alarms and messages that ensure the correct func-tion of the system.The Implantable Insulin Pump alarm system will “beep” when certainconditions occur. The beeps are designed to be audible through the skinand 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, 4double tones each minute for 10 minutes and repeat the pattern. Uponhearing the alarm, the patient must communicate with the PPC, to deter-mine the alarm condition. The alarm can be cleared by pressing SEL thenACT. The following descriptions explain the alarm conditions the systemmay encounter.The PPC has three types of alarms: audible, vibrate and visual alarms.The chapter will describe for each alarm condition, which screen messageappears 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 secondsevery minute for 30 minutes. If the PPC is set to “audible”, the PPC will beep 6 times every minute for30 minutes. If the alarm is not cleared in 30 minutes, the PPC will beep 6alternating tones. The PPC will continue to do so every minute.Dmp9196021-011_c.book Page 117 Wednesday, April 3, 2002 5:06 PM
System Alarms and Messages118Alarm Type 2:If the PPC is set to “vibrate”, the vibrator will be turned on for 3 secondsevery 30 minutes while the condition exists. If the PPC is set to “audible”, the PPC will beep 3 times every 30 minuteswhile the condition exists.Some alarms can be cleared by pressing SEL then ACT.Pump alarmsAlarm feedbackThe Alarm Feedback function allows the user to verify the Pump andPump 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”, thePump will beep on each of the first five Pump strokes:• Following a change in the delivery regimen, for example whencompleting a meal Bolus and then changing to a Basal Rate, or atthe start of a bolus.• After the Alarm Feedback function is programmed “YES.”Alarm Feedback will stay on until programmed back to “NO.”Pump low batteryThe Implantable Insulin Pump battery is designed to last approximatelyten years during conditions of normal use (see Chapter 11, TechnicalSpecifications). Battery life may vary somewhat depending upon a user’sinsulin delivery requirements. When battery energy becomes low, a volt-age sensor in the Pump will trigger the Pump Low Battery Alarm. APump Low Battery Alarm indicates there is approximately eight weeks ofbattery energy remaining. Dmp9196021-011_c.book Page 118 Wednesday, April 3, 2002 5:06 PM
Pump alarms 119The Pump Low Battery alarm can be cleared and the Pump will continueto operate normally. However, users should be instructed to report thealarm immediately to their physician. A Pump replacement or resumptionof conventional insulin therapy should then be scheduled. Depleted pump batteryWhen there is no longer sufficient battery energy to power the Pump, thePump Low Battery Alarm will cease and insulin delivery will stop. Alter-nate insulin therapy must be initiated.System errorThe Implantable Insulin Pump has a sophisticated self-monitoring systemthat periodically checks for circuit faults. If a fault should occur in thePump electronics, insulin delivery will stop. Conventional insulin therapymust be initiated immediately. Using the PPC Supervisor Mode, the phy-sician should use the “DOWNLOAD SOFTWARE” feature to reprogramthe Pump from software in the PPC memory. Notify MiniMed immedi-ately.PPC Display Type of Alarm Pump AlarmPUMP LOW BATTERY1 In 24 hours if no PPC communicationPPC Display Type of Alarm Pump AlarmPUMP STOPPED1 or 2 or 3 or 4 or 5 or 61 In 5 minutes if no PPC communicationDmp9196021-011_c.book Page 119 Wednesday, April 3, 2002 5:06 PM

NotifyMiniMed immediately. PPC alarmsThe PPC offers a choice of two alarms, audible and vibrate. In addition, ascreen message appears indicating the type of alarm condition thatoccurred. PPC low batteryIf 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 batteryshould 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 PumpCommunicator).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.PPC Display Type of AlarmPUMP SELF TEST FAIL1PPC Display Type of AlarmPPCLOW BATTERY1!WARNINGDmp9196021-011_c.book Page 120 Wednesday, April 3, 2002 5:06 PM

131CHAPTER 10 Troubleshooting Pump System Under-deliveryPotential under-delivery of insulin by the Medtronic MiniMed 2007CImplantable Insulin Pump System may result in an increase in daily pro-grammed insulin usage, difficulty maintaining euglycemia, occasionalhyperglycemia, and problems calculating refill accuracy. This chapterdescribes how to diagnose potential Pump System problems that maycause insulin under-delivery, and offers potential Pump and Catheter solu-tions to correct for under-delivery.Diagnostic proceduresWhen refill procedures reveal the possibility of a Pump System under-delivery problem, diagnostic procedures must be performed to verify ifthere is a problem with either the Pump or Catheter. The Stroke VolumeMeasurement Procedure tests Pump function, while the Pressure Mea-surement Procedure tests Catheter patency. These diagnostic proceduresshould be performed according to the steps outlined in Appendix G andAppendix H, respectively.Under-delivery caused by backflowBackflow 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 insulinback into the reservoir. To compensate for this under-delivery, the usercan 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-delivery132Backflow conditions are characterized by increases in daily programmedinsulin usage, difficulty in maintaining euglycemia, increasingly negativerefill accuracy and sometimes hyperglycemia. Conform a backflow con-dition by performing the Stroke Volume Measurement Procedure. Thenrinse the Pump System with NaOH solution to dissolve insulin deposits,following the Pump Rinse Procedure outlined in Appendix E.Under-delivery caused by catheter occlusionUnder-delivery caused by Catheter occlusion can occur either abruptly orgradually. The insulin usage and clinical symptoms are identical to thoseof Pump under-delivery. Confirm a Catheter occlusion condition by per-forming a Pressure Measurement Procedure. Then perform the followingprocedures to clear the occlusion:• First, flush the Catheter by using the Side Port Catheter FlushProcedure outlined in Appendix F.• If the Flush Procedure is unsuccessful, replace the Catheter.Catheter replacement surgery should be performed in a manner similar tothe initial Pump System implantation. PPC initialization will not be nec-essary. However, after the Catheter replacement, Pump function anddelivery verifications must be performed.Dmp9196021-011_c.book Page 132 Wednesday, April 3, 2002 5:06 PM
