Technology in Diabetes Flashcards

A patient reports their CGM consistently reads high during exercise compared to fingerstick results. What is the most likely physiological explanation?

Answer: Blood glucose rises faster than interstitial glucose during exercise-induced glucose spikes

During rapid glucose rises from exercise-induced hepatic glucose output, blood glucose can increase faster than interstitial fluid glucose, causing CGM to lag behind.

Which technology is used in the Omnipod 5 hybrid closed-loop system to wirelessly communicate between the CGM and the pod?

Answer: Bluetooth

The Omnipod 5 uses Bluetooth to communicate between the compatible CGM (Dexcom G6) and the pod controller for automated insulin adjustments.

According to ADA standards of care, what Time in Range (TIR) target is recommended for most adults with type 1 or type 2 diabetes?

Answer: >70%

The ADA recommends a TIR target of greater than 70% (glucose 70–180 mg/dL) for most non-pregnant adults with diabetes.

A patient calls stating their pump has an 'E1' or 'motor error' alarm. What is the appropriate educator response?

Answer: Advise the patient to contact the pump manufacturer and use injection therapy in the interim

A motor error indicates a mechanical pump failure; the patient should switch to injection therapy and contact the manufacturer for device replacement.

When using telemedicine visits for diabetes technology management, which CGM data-sharing method is most commonly used to review patient glucose trends before or during a visit?

Answer: Provider remotely accesses the patient's CGM app via cloud-based clinic software (e.g., Dexcom Clarity, LibreView)

Cloud-based clinic platforms like Dexcom Clarity and Abbott LibreView allow providers to view comprehensive CGM reports before or during telehealth appointments.

A patient on a sensor-augmented pump (SAP) needs MRI imaging. What is the standard recommendation regarding their devices?

Answer: Both the pump and CGM must be removed before entering the MRI suite

Both insulin pumps and CGM transmitters/sensors must be removed before MRI imaging because the magnetic field can damage devices and the metal components pose safety risks.

A CDE is educating a patient about interpreting the GMI (Glucose Management Indicator) from their CGM report. What does GMI represent?

Answer: An estimated A1C calculated from average CGM glucose over the reporting period

GMI is a formula-derived estimate of A1C based on average glucose from CGM data and provides a timely approximation without a laboratory blood draw.
