| | | Wow, I'll bet that not many users follow these recommendations. It is interesting to see in this article how different the usage profiles are by pump manufacturer.
My duration is set to 3 hours and I am a Cozmo user. According to this article, I should have the duration set to at LEAST 4.5 hours. I am willing to give this a try, but I'm wondering how this will impact my carb ratio. Certainly I will need more insulin per carb if I am to maintain my 2-hour post-prandial reading, right?

Unless of course you eat more often and always have active insulin on board during a meal. Then yes, they may change it slightly.

| | | My endo recommeded 3.5 hr duration and I fell into the trap detailed in the article referenced by xMenace. I did 1.5 years of insulin stacking which always seemed to hit exactly at 3:00 every afternoon. After asking DF for their best pump tips I reset my duration to 5 hrs and my 3:00 lows have disappeared. I consulted with a pharmacist and a book Called Pumping Insulin 4th edition. I had to reset my basal rates but now my BG readings are very consistent and hopefully my A1C will show it next month. Hang in there, experiment and ask. |

If I bolus every 3-4 hours for something and I am not experiencing hypos from this stacking with an artificailly short duration, don't you think my correction factor might actually be different?

| | | Sleepy: I got the Minimed 522. I had several to chose from, but ended up chosing between the animas 1250 something and this one. Looking back i think i should have chosen the animas, it seems a bit sharper, but then again i can always switch later on.
I am very happy with the pump though, just to be able to shut it off is awesome, since my basal is 0.20 and 0.10 units. haha, honeymooooon.
