Since having my pump my active insulin time has changed from 6 to 4 hrs - my DSN was sceptical at first but I have convinced her that 6 hours, which is my hosp default, is too long for me personally. I''ve stuck with 4 for a while but I'm almost convinced that it should be changed to 3hrs (wish I could change it to 3.5). So many times I find that the pump will suggest no insulin correction as there is active insulin on-board but almost every time I have to overide this as I know that I will need additional insulin to bring my sugars down. Does anyone else have their active insulin time set to 3 hours?
 
Hi
I had exactly the same problem as you and often had to override the suggested correction doses as the amount of insulin on board was too high. I do think though that I seem to have a kind of sixth sense about the amount of correction needed and also It seems to vary according to the time of day.
I have set my active insulin time to 3.5 and it works much better.
 
Thanks for reply. Will see how it goes for a few days now. Don't know about everybody else, but my blood sugars at the moment are very random. I often find this going into nov and dec - frustrating thing is they're not consistently random!! :crazy: Highs during the night sun and mond and then low during last night - all over the blinkin place.
 
I'm sure that the 4hrs that is set as the active time on my pump isn't correct either, but haven't been able to convince them of this yet. It almost feels like the active time should be different at different times of day as it is only in the evening that I don't trust what it is saying about the amount of insulin on board and I then have to make some random guestimates in my head about the correction required.
 
Hmmmm

Combo pump hasn't got IOB feature so I think it relies soley on the bg test being done in order to calculate correctly.

Am wondering if it might pay to change the target levels at different times in order to get the pump to bolus correctly or change the basal rate down so that bg levels are a tiny bit higher and then that should prompt the pump to do the correction.
 
I've been on the Animas Vibe for about 8 months and I didn't know about changing the active insulin time. I'd prefer to do this, I find that quite often, I have to add an extra bolus as the pump won't let me have enough insulin. I'm going to check my manual and change the time length, or will doing this mean my Star DSN won't talk to me anymore!?!?!?!?
 
Well it's hard to say if the 3 hours works or not as my Blood sugars have been randomly horrible for the last week so very difficult to gauge what's happening :crazy: and no, there seems to be no rhyme or reason for the higher blood sugars. When do I permanently change the basal rates is the question, as using a temporary basal for now. I have been doing corrections based on 3 hrs active insulin time and not a hypo in site but, as I say, that maybe due to the increased insulin I'm needing at the moment.
 
Type 1 would be so much easier to manage if everything about it wasn't so random :roll: :roll: Just start to think boluses are right and it all goes out of the window :problem:
 
Soooo agree. It's the curve balls that get me and they are impossible to predict and even harder to manage sometimes. I think I've listed elsewhere to say that I always seem to have issued with my diabetes in Nov and Dec. Someone up there is trying to spoil Christmas I think!! On saying that we somehow manage and it's when I feel sorry for myself I sit back and look at the horrors going on in the world that I realise things could be so much worse. :thumbup:
 
Dont forget if bg levels over 12 then correction bolus's are advised to be doubled up..

I had this recentlywhen two lueur locks on the combo pump managed to start working themselves undone without me realising... And my bg levels shot up to something quite extreme...I remembered being told to double up correction bolus in these instances... And yes it did work, and no.. I didntgo hypo.

Two of my lueur locks from a new box were working loose.. 1st time this has ever happened to me. I changed to use a different batch and these lueurs are back to normal.....
