How it Works

It reads the blood glucose level (BG) from the Navigator CGM. The goal level = 100.

Insulin starts at .5 units per hour. As the algorithm gets data from the CGM, it “learns” how successful it has been.

If the BG is less than 100, then Glucagon is administered. For adults, the general dosing is 10-15 units to raise BG 50 points. It uses this baseline to calculate glucagon dosing for how much below 100.

The other CGM’s are being used to document their accuracy so that the FDA and the manufacturers of those CGM’s can see how accurate they are. This information will be used to validate, or improve the systems.

Day 1 – Post Lunch

T – 5 minutes until the pods go on. One for Humalog and one for glucagon.

T – 65 minutes until the study officially starts.

Here’s how the numbers read right now, 1.5 hrs post lunch (116 g carbs and 11 units of insulin. Pizza too)

My Dexcom – 115
GlucoScout – 98 (Actual blood test)
Study Navigator – 129

All I can say is, I can calculate a bolus!
