CDE Technology in Diabetes 4

Question 1

Which statement best describes the role of a 'bolus calculator' or 'insulin-on-board' (IOB) feature on an insulin pump?

Accepted Answer

It estimates active insulin from recent boluses to prevent stacking

Answer

The IOB feature tracks insulin still active from recent boluses and subtracts it from correction calculations to prevent insulin stacking and hypoglycemia.

Question 2

A patient asks about implantable CGM options. Which device is an implantable CGM with a wear period of up to 180 days?

Accepted Answer

Senseonics Eversense E3

Answer

The Senseonics Eversense E3 is an implantable CGM worn subcutaneously for up to 180 days, requiring professional insertion and removal.

Question 3

Which technology allows patients to share real-time CGM data with caregivers or healthcare providers remotely?

Accepted Answer

CGM cloud-based sharing platforms (e.g., Dexcom Follow, LibreLinkUp)

Answer

Cloud-based sharing platforms like Dexcom Follow and Abbott LibreLinkUp allow real-time CGM data to be shared with followers across any distance via internet.

Question 4

When reviewing pump settings with a new insulin pump user, what does the 'carbohydrate ratio' (ICR) determine?

Accepted Answer

How many grams of carbohydrate one unit of insulin will cover

Answer

The insulin-to-carbohydrate ratio (ICR) specifies the number of grams of carbohydrate that one unit of insulin covers at mealtime.

Question 5

A diabetes educator is helping a patient interpret their CGM glucose variability. A coefficient of variation (CV) above what threshold is considered high glycemic variability?

Accepted Answer

36%

Answer

A CV above 36% is generally considered high glycemic variability and is associated with increased hypoglycemia risk regardless of mean glucose.
