I don’t really understand your question. Really your settings shouldn’t change because your weight is already in there. I assume your carb ratio is also in there.
The only difference is that it will bolus when you are high.
But I never let it get that far because I correct before the software does.
I run in sleep mode most of the time.
I reduced my insulin sensitivity and carb ratio just so I could get a little tighter control.
I use a little more insulin than on my last pump. I was 45 per day now I’m more like 50, but it varies more some days it’s 42 some days it’s 60. And thats because it changes my basal as needed
I read that to maintain tight control I should put my weight and TDD settings to max. When I enter my settings to start off, should I start off with my real weight and TDD and slowly raise them or start off right away with weight and TDD maxed out.
Weight is one of the many factors that puts limitations on the Control-IQ algorithm. It’s a choice only you can make for yourself, but using the max weight removes that one factor, giving Control-IQ a little more freedom to dose for you.
TDD is another one of those limiting factors, but that setting is moot after the first day or so. The pump will use your actual data, rather than the setting you enter, once it has accumulated enough.
These are small safety measures, though. They just determine the maximum amount of extra insulin the system can deliver. They don’t in any way define how much is given at a particular moment. They’re not the basis of operation. The key to tight control will come with tweaking your basal rate(s) and correction factor(s) (which determines how aggressive Control-IQ works).
Control-IQ works fine for me at my correct weight. I would start with normal settings and adjust gradually from there to fine tune. For me this technology allows me to sleep without giving insulin or eating carbs two or three time a night. A true gift! I have always been a fan of trying things out on myself so you can be bold as long as you are watching your BG. Experiment but be safe.
Thanks for the comments, that is what I was looking for. When starting with BIQ, I thought a good strategy was to be aggressive with basal settings to take advantage suspending delivery when going low, which is not what my diabetes specialist believes, who feels it is a sign that basal settings are wrong whenever there is a suspension.
This mindset irks the heck out of me. The whole medical field is terrified of hypos, and they use a random benchmark to determine this which isn’t even considered a hypo in non-diabetics. But it’s how they’re trained.
The suspension is an incredible tool for overcoming the shortcomings of our insulin. That darned tail that keeps you falling 3-5 hours after you bolus. That “suspension means your settings are wrong” mindset essentially equals “you HAVE to be high post-prandial if you eat carbs, to leave room to fall 3-5 hours later.”. That’s exactly why the 70% TIR goal is so low. There is zero reason to abide by that mentality if you can do better safely.
I think the ability to “super bolus” is the single greatest advantage of these automated systems. It let’s you give extra insulin up front where you need it, and redirect that annoying lingering tail to be basal insulin instead, by suspending the programmed basal.
Thank goodness my doctor knows better than to try and interfere with my management techniques!
The only caveat with Fiasp is that it is not FDA approved for use in pumps and I find that the insulin crystalizes and occludes my entire set up during day 3
The additive taht makes it absorb faster interacts with the plastic in the tubing and cartridge and crystallizes.
Happens more in tubing because there is less insulin in the tubing.
That’s why tandem will tell you to only use humalog or novolog.
I know that if you want to use it anyway. Use 80 percent and 20 percent humalog. So if you are loading 100 units. Just put in 80 of fiaspand 20 of humalog. It’s enough to prevent crystallizing. While giving almost the same action as fiasp alone.
Have you tried Lyumjev? Do you know if it has the same crystallization issues?
I’m going to ask my doctor about getting a tandem pump with control iq. My insurance covers Lyumjev. I’m currently on MDI and like Lyumjev’s action profile a lot.
Nope I’ve used fiasp and it clogged so I diluted it 80 percent to 20 percent humalog.
I’ve also used novolog and currently using humalog because my insurance pays for it. I would try lyumejev tho if I had some.
What’s the worst that can happen?
