Omnipod Insulin Management System

Omnipod 5 dexcom integration

Features

  • Automated Insulin Delivery Pump (SmartAdjust algorithm) uses Dexcom G6 and G7. 
  • Tubeless; small waterproof pods adhere to skin, contain the algorithm, have self-inserting angled cannula and communicate wirelessly to a Personal Diabetes Manager (PDM, that looks like an Android phone). The Omnipod 5 in Canada does not yet operate from a cell phone. 
  • Omnipod 5 PDM comes with an Insulet SIM card to automatically upload results to Glooko.  (The PDM cannot be used as a cell phone. No cell phone plan is required for the PDM to function.)  All insulin programming and new pod changes are done via the "app" in the PDM.  Future upgrades will be done through the PDM SIM card.
  • The user requires a separate phone to activate each Dexcom glucose sensor. However, after activiting each new sensor, the phone is not needed until the sensor is deactivated and a new one inserted. The sensor communicates directly with the Pod. Pods communicate directly with the PDM.
  • Different glucose targets can be preset for up to 8 different times of the day. 

 Omnipod SmartAdjust Algorithm

  • The algorithm determines the "Adaptive Basal Rate". When in "Automated" mode, the algorithm does not use the programmed manual basal rates. "Adaptive Basal Rate" is based on Total Daily Insulin for the past 4-5 pods. 
  • Pods contain the algorithm. The algorithm is updated every 2-3 days with a pod change.
  • Basal insulin is assessed every 5 minutes based on the current sensor glucose value, trend, predicted value 60 minutes out and the target chosen. The pod then increases, decreases, or pauses basal insulin. 
  • The algorithm may increase the automated basal by up to 4 X the "Adaptive Basal Rate".
  • Only basal modulation is provided based on the algorithm's determination of basal needs. 
  • The bolus calculator uses the following information:
    • Inputted carbohydrate
    • Manually programmed carb ratios
    • Manually programmed correction factors
    • Sensor trends
    • Insulin on board (past bolus + any basal delivered "above" the Adaptive Basal Rate)
  • Initial Setup
    • POD #1: For this limited time, the algorithm uses the active manual basal program (and parameter that 50% of total daily insulin is basal) to determine the first "Adaptive Basal Rate". Expect the first 2-3 days' time in range to be lower than desired.
    • POD #2 (at least 48 hrs after pod 1): The algorithm adjusts using total daily insulin from first pod. 
    • With each new pod: The algorithm adjusts according to total daily insulin, with the past 4-5 pods having the greatest impact.
  • More Setup Information
    • More agressive carb ratios may be required compared to multiple daily injections.
    • Most will disable the "Reverse Correction" setting. 
    • Active insulin time often set to 3-4 hour 
  • Features NOT availagble in Automated Mode
    • No extended bolus in "Auto"
    • No temp basal in "Auto"

FYI & Misc

  • Omnipod 5 vs Omnipod use in Loop DIY AID (video, Loop & Learn)
  • Pods can only be purchased via Diabetes Express or Richmond Square Pharmacy in Calgary.
  • Advise to change set if notice tunneling or corrections that are not returning glucose to target. Tunneling is the wetting of the material of the pod (insulin travels back up after delivery). It often occurs with movement of the pod (laying on or just day to day movement after a few days) or bigger boluses. Consider extended boluses, different sites, more frequent pod changes,
