    Study Notes

    DEXCOM G7 Continuous Glucose Monitor

    • Designed for real-time glucose monitoring, offering faster readings, improved accuracy, and enhanced features compared to earlier versions like the G6.
    • Offers predictive alerts, allowing patients to make timely insulin adjustments.
    • Model Comparisons:
      • G7: 8.2% accuracy (lower percentage is better), 30-minute sensor warm-up time, usable with pregnancy, smaller and more discreet.
      • G6: 9.8% accuracy, 2-hour warm-up time, not usable with pregnancy, no grace period.

    Sensory Placements

    • Adults: Upper arm or abdomen.
    • Children: Typically placed on the back of the upper buttocks due to less fat.

    Avoid Areas

    • Areas patients lie on while sleeping.
    • 3 inches from infusion/injection sites.
    • Areas near waistbands, irritated skin (e.g., wounds, tattoos), or highly muscular areas (may cause inaccurate readings).

    Improved Size and Functionality

    • Wear Duration: 10-day sensor lifespan with a 12-hour grace period for replacement.
    • Faster Alerts & Alarms: Predicts low glucose levels 15-20 minutes in advance for timely intervention.

    Unique Canadian Approvals

    • Only CGM approved in Canada for pregnancy.
    • Only CGM that integrates with insulin pumps.

    Glucose Sharing

    • Data is shareable with up to 10 people via internet connection.
    • G7 is waterproof for up to 24 hours.

    Prescription Information

    • Dexcom provides prescription pads to doctors, simplifying the process.
    • Auto applicator for ease of use.
    • Only available through pharmacies in Canada.
    • Does not have coverage under the Ontario Drug Benefit (ODB) or Assistive Devices Program (ADP).
    • Private insurance coverage is possible; check with plans.

    Medication Interactions

    • Hydroxyurea (used for cancer and blood disorders) can interfere with Dexcom G7 sensor readings.

    Clinical Use

    • Particularly beneficial for Type 1 or Type 2 Diabetes patients needing consistent real-time glucose monitoring.
    • Predictive alerts and pump integration make it a valuable tool for proactive glucose management.

    INSULIN PUMPS

    • Cost: Approximately $7,000 for a new pump, with government funding available for every five years.

    • Annual supplies cost around $2,400.

    • Pump Features:

      • Tubing holds 200-300 units of insulin.
      • Reservoir filling requires refilling the pod reservoir every 3 days.

    • Insulin Delivery:

      • Pumps use fast-acting insulin.
      • Deliver small doses every few minutes to keep blood sugar within a desired range.

    • Insulin Sets: Available in various types for different body types, with alternatives for patients with Teflon allergies.

    • Integration: Can integrate with continuous glucose monitors (like Dexcom G6 or G7).

    • Insulin Pump BRANDS and features:

      • Tandem:
        • Originally dual-chamber (insulin and glucagon) but now only for insulin delivery.
        • Integrated with Dexcom G6 for glucose monitoring.
        • Infusion sets are rechargeable.
      • Medronic:
        • Manufactures everything in-house (including infusion sets).
        • Uses their own sensory monitoring system (Enlite), which is less accurate than Dexcom sensors.

    Key Considerations for Diabetes Devices

    • Pregnancy: Managing diabetes during pregnancy requires extra care and monitoring.
    • Infusion Sets/Teflon Concern: Ensure alternative infusion sets are available for patients with Teflon allergies.
    • Pump Maintenance: Regular checks and replacements (pod or infusion set) are necessary.
    • Age 65+ can apply for a grant that covers costs.

    CONTOUR NEXT GEN GLUCOSE METER

    • Brand: Ascensia.

      • Reusable test strips within 60 seconds if the blood sample is insufficient.
      • Can be affected by certain substances (like citrus).
      • Colorful lancets for easy identification.

    Usage Tips
