I don’t currently wear a pump. For the brief period that I did, I started with it set to 4 hours and later decreased it to 3 hours.
With Novolog, 4 hours. If someone knows a more accurate number, please let me and others know. Thanks. ʕ•́ᴥ•̀ʔっ
I think there is no ‘accurate’ number. It is all dependent on the individual’s response to the insulin they are using.
Using Aspart I have mine set to 3 hrs. I tried 2.5 and 4 and it really does not seem to make a lot of difference, but 3 hours, for me, seems to give the best results. Everyone is different in their insulin response.
From what I was told the algorithm only uses one setting and it has nothing to do with reality???
I believe my t-slim Tandem is preset for 4 hours
Tandem CIQ sets it at 5hrs as a default and you can’t change it unless you turn it off which I do sometimes. Previously, I had it set for 3.5 hrs for aspart.
Normally set at 4 hours, but throughout my pregnancies this shortens to 3 hours, then 2 hours by the end.
TSlim’s Constant for their Algorithim is 5 hours, I can not change this.
Tandem Control IQ sets it at 5 hours, otherwise I’d have it set at 3 hours.
There are a lot of factors involved in DIA. Is humalog or one of the ultra rapid insulins like fiasp or lyumjev? Looping or non looping? Then on top of that there’s the individual factor.
I’m a DIY Loop where 6 hours duration probably is the most common
Using Dexcom control IQ. It is preset to 5 hours
Not sure but I think this refers to Activity on Tandem pump. On a normal day i set activity from 9 to 5. As I am very busy most of the day. My CDE told me to. Lots of gardening, walking, cleaning, carrying things, I’m also the fix- it man’s ever present assistant when he’s working. Busy busy busy
I use Tandem CIQ so 5 hours, but before that used 3 hours, which worked for me.
Oh, oops. Didn’t understand the question Mine is set for 3.5. Control IQ. Humalog.
Not an adjustable feature when using CIQ with Tandem Insulin pumps.
If using tandem’s control IQ system, you’re required to use the 5 hour active time for insulin. You cannot adjust it. If you do want to adjust it, you have to turn off the control IQ feature.
I’m using Control-IQ on my Tandem pump and that’s set at 5 hours. If I could adjust it I’d use a 3 hour duration.
I’d have to change my answer from 4 to 5.
I have it set as 5 because of control iq, but without, I use 4
I’m sorry. But, I didn’t understand the question.
I said 3 hours because the specific setting at 12 pm I starts at that time and then switches at 3 pm to a different setting but don’t understand the meaning it goal of this question.
I have, like I’m sure everyone else has, different settings during the days.
Okay, now I understand. I have my insulin set at 4 hours of activity.
5 hours, I don’t have a choice using tslim CIQ. I believe my Medtronic pump was set to 3 hours.
Active insulin duration set at 5 hours via Tandem CIQ pump works for me. I trust it and TIR is ~ 88 to 92%. After nearly 60 years with T1D in my body, I am pretty happy with that. Why mess with what’s working?
I am on the t slim with CIQ. It is preset at 5 hours.
Wow, nothing confusing about the “Active Insulin Duration”, mixing the two Active Insulin Time and Insulin Duration Time, two different things!
Insulin Action Time = “Time that the insulin will continue to lower blood glucose” Active Time
Insulin Duration Time = “Length of time is take insulin to not impact blood glucose” Still detectable in your system.
After reading the answers and explanations I can answer that my Tandem tslimx2 pump is set for 4 hours active insulin time.
I don’t understand the question. I have Control IQ.
Gee. Results would have more useful info if it limited type to insulin aspart Novolog or Humalog only. I know an increasing number of ppl using fiasp & other fast-acting / fast uptake insulins **in their pump**. It baffles me on how their pump’s algorithm can handle that behavior with their active CGM controlling some aspect of their pump operation (i.e. Tandem X2 C-IQ).
I use Loop app algorithm, which I believe is set for 6 hour duration
As I am sure that others have commented on, if you use the Tandem Tslim:X2 pump and you have enabled Control IQ, you are fixed at a 5 hour duration. While I understand why they fix the duration at that amount, I don’t think it is appropriate for everyone. In some cases, you have to ‘tweak’ your boluses at bit to compensate.
Tandem pump with Control IQ has a set Active Insulin time that is not customizable (5 hrs if I recall).
When I go back to DIY loop soon, I will change from 4 hours to ~5.5
