I use Dexcom G4, is it time to switch to G5?

[Terry4]

I use the do-it-youself automated insulin dosing system, Loop. The Dex G4 + Share is the CGM component of my system. Here are my initial notes when I started in November 2016.

Loop -- a dynamic answer to a dynamic problem

I recently started using Loop, a hybrid closed-loop artificial pancreas (AP) system. I encountered some start-up difficulties with two consecutive infusion site failures and miserable numbers. I put in another style infusion set yesterday and my metabolic world changed. I woke up this morning to this overnight CGM trace: [image] yellow line=140 mg/dL, red line=65 mg/dL Time in range = 100%, time hypo = 0%, standard deviation = 8 mg/dL, average BG = 103 mg/dL I have had success approaching thi…

This is a follow-up post one year later.

The one-year Loop milestone, how did it perform?

Today marks my first anniversary of closing the loop using the do-it-yourself automated insulin dosing system, Loop. This is a hybrid system in that one must announce meals and tell the system how many carbs I’m eating and when. Loop examines the blood glucose level, insulin on board, insulin sensitivity, and carbs on board every five minutes and then decides whether to increase, decrease, or maintain my pump’s basal rate. Here’s my post about Loop from one year ago. I am thrilled with the resu…

I love this system and wouldn’t choose to return to my former pump/CGM use. It’s not perfect and not quite as automatic as this tech promises to become. The system looks at my blood glucose level every five minutes and calculates whether to add, subtract, or stand pat with my pump’s programmed basal delivery. It then tells the pump what temporary basal rate or it remains on the pump’s programmed basal rate.
