I wanted to jump in with perspective on the closed loop systems, as that seems to be a big part of your issues. I also have a 670g, and run auto mode. The need for calibrations and BG requests are really maddening! I call this pump my ‘baby’ because it wakes me up, and cries, on a regular basis. The only assistance I can offer is there is a setting, under options, smartguard, auto mode, then auto mode bg alert. I have that turned off so the the BG required message doesn’t wake me up.
As of last Wed, my 10 yo son, also a T1D, started the Tandem Tslim w/Control IQ using the Dexcom…so much better!! We are still learning it, but there are less issues and the system seems much easier. If you have any way to switch, I do think you will have more success.
I would see what the return policy is for Medtronic, or what your options are with insurance for switching, since you are having so many problems. My understanding is, insurance companies are getting numerous requests to switch - but without a real reason, they won’t budge. Your doctor should be able to prove your need to switch…
There are some but not many people on the forum who can share first-hand experience having used both devices, and that is always particularly enlightening. Yours isn’t quite did- hand🤔 but I look forward to reading your input. It sounds like you’ll want to make the switch when your warranty runs out. How much longer are you locked in if you’re not able to make a case with insurance to change sooner?
Wishing you and your son all the best.
Yes. I looked into switching as we were getting approval for my son’s pump. Im locked in for 4 years…only 1.5 yrs in right now, so it will be a while. My doctor, who is a Medtronic pump trainer, has even said he is way more impressed with the Tandem option.
I have been trying to understand how the 2 systems work, compare/contrast. My understanding is Medtronic is more AI based. The pump is learning you and your rhythms. Thats why starting is much harder, as the system is learning about you and not always getting it right.
Control IQ is using basal settings, but reading the cgm, 30 min predictive, and changing basal rates accordingly. It can also give boluses for highs. For my son, we are just starting, and there are tweaks. But, it has kept him much steadier. One thing we deal with, and other parents may be dealing with, is his active hormones at bedtime. Growth hormone is very active and creates insulin resistance, so he shoots up to 300. With the right settings, Control IQ should be able to smooth that out.
You’re right, it is like having a baby! That thing goes off half the night asking for a bg but it doesn’t want my bg from the glucose meter but the sg reading. Of course, at night I don’t have my glasses on and and half asleep when it goes off so it doesn’t always register in my brain. It’s maddening for sure!!
Karen @T1Dx2, I haven’t used the 670G so I won’t comment on that system. I have used the Tandem Dexcom system with CIQ for ten months with positive results.
Your understanding of CIQ is pretty good, in general, and you should be able to offer guidance to your son. There are many little things besides hormones that could cause BGL readings above 300 in the evening-look at the bigger picture. In order for CIQ to work well, it needs him to accurately input all data, including the extra snack. I was once a team living with diabetes.
Consider too the supper foods that have delayed glucose release.
