  • Benefit of pump + CGM (not just CGM)This is the foundation for an artificial pancreas
  • Here’s how the feature works:User settable: On/OffLGS setting range: 40-110 mg/dL, default: 60 mg/dLWhen triggered, the feature suspends insulin infusion for up to 2 hours:Continuous audible alarm and continuous display of an emergency messageCan resume insulin delivery and cancel LGS at any timeCannot deliver a bolus when suspendedAfter 2 hours, pump resumes basal insulin delivery for 4 hours The 6-hour cycle will continue until LGS is cancelled or current calibration expires(Note: if asked about the 2 hour resume, it came from 23 million pump days analyzed in CareLink from 1/1/04-8/23/09. This was equal to 9,634,009 suspends with (281,270 for 2-3 hours and 270,454 for 3-5+ hours)

    4. 4. More Information – MORE DATA with Continuous Glucose Monitoring NUMBER OF CONTINUOUS GLUCOSE READINGS PER105,120 YEAR (288 per day x 365 days) NUMBER OF FINGERSTICK MEASUREMENTS PER1,460 YEAR (4 per day x 365 days) •Medtronic 4 Diabetes
    5. 5. Continuous Glucose Monitoring Technology: Personal Use Personal CGM Paradigm and Guardian • For use by people with insulin-dependent diabetes • Real time displays of glucose values and trend graphs Allows You to Proactively • Retrospective data through CareLink Respond to Changes in Your Glucose Levels to Improve Control Real time CGM reveals fluctuations in your glucose levels that you can’t see through A1C tests alone*. •Medtronic 5Levetan C, et al.

    12. 12. Step 2: Set High Sensor Glucose Alert Turn on High SG Alert30060 •Range between High and Low Alerts is WIDE. •Focus on safety, while learning how to understand CGM trends. •Medtronic 12 Diabetes
    13. 13. Step 3: Tighten the Sensor Glucose Alerts Low SG Alert is 70 mg/dl High SG Alert is 250 mg/dl25070 • High and Low Sensor Glucose Alert thresholds are now closer to target range. • Adjust based on individual needs. •Medtronic 13 Diabetes
    14. 14. Step #4: Add High and Low Predictive Alerts Predictive Alerts occur BEFORE the threshold.25070 • Optional Alert setting. 1:33P HIGH PREDICTED • Start with 10 minutes for Predictive Alerts, then adjust as needed. •Medtronic 14 Diabetes
