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 conditions 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 determine 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. Dmp9196021-011_c.book Page 118 Wednesday, April 3, 2002 5:06 PM 118 System Alarms and Messages 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 Feedback to measure the time intervals between Pump strokes to verify accurate 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 voltage 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 119 Wednesday, April 3, 2002 5:06 PM Pump alarms PPC Display Type of Alarm Pump Alarm PUMP LOW BATTERY In 24 hours if no PPC communication 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. Alternate 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 physician should use the “DOWNLOAD SOFTWARE” feature to reprogram the Pump from software in the PPC memory. Notify MiniMed immediately. PPC Display Type of Alarm Pump Alarm PUMP STOPPED 1 or 2 or 3 or 4 or 5 or 6 In 5 minutes if no PPC communication 119 Dmp9196021-011_c.book Page 120 Wednesday, April 3, 2002 5:06 PM 120 System Alarms and Messages 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 Display Type of Alarm PUMP SELF TEST FAIL 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 following alarm display appears each time a new function is programmed: PPC Display Type of Alarm PPC LOW BATTERY Clear this message by pressing SEL and then ACT. While the battery should have sufficient energy for a few additional programming commands, the battery should be changed as soon as possible. For instructions on changing the battery, (see Chapter 3, Personal Pump Communicator). WARNING If “VIBRATOR” is selected, the PPC battery should last about six weeks during normal use conditions. If the PPC determines that the vibrator is causing a low battery condition, it will automatically change the Alarm Mode to “LOW VOLUME” in order to extend battery life. Dmp9196021-011_c.book Page 121 Wednesday, April 3, 2002 5:06 PM Pump alarms NOTE: If while programming the PPC, the screen goes blank, the PPC beeps six times and then the “CHECK PUMP STATUS” message appears, the battery needs to be replaced. (See Chapter 3 for instructions, Install/Replace the Main Battery). PPC depleted battery When the PPC main battery (AA 1.5 volt alkaline) no longer has sufficient power to program the Pump, the following message will appear on the display: PPC Display Type of Alarm PPC DEPLETED BATTERY This message can only be cleared by replacing the PPC battery.

This chapter describes how to diagnose potential Pump System problems that may cause insulin under-delivery, and offers potential Pump and Catheter solutions to correct for under-delivery. Diagnostic procedures When refill procedures reveal the possibility of a Pump System underdelivery 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 Measurement 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 System. Backflow is caused by insulin deposits that compromise valve integrity, 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 132 Wednesday, April 3, 2002 5:06 PM 132 Troubleshooting Pump System Under-delivery 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 condition 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 performing 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 necessary. However, after the Catheter replacement, Pump function and delivery verifications must be performed.
