Cooked?

So I’ve been exercising with my sisters-in-law at night to try to lose some weight and get “fit” before vacation next month. Last night, we went walking (2.8 miles!! yay!) and for a 1/4 mile, I ran {yes, me, I finally ran 1/4 mile straight!}. The only thing is, my pump (the t:slim) was right next to my body.

Today, I’ve been having issues with highs. Like, spikey ones and ones that make me sick to my stomach. I haven’t had this in a while, and I’m worried about if the heat cooked my insulin? I know others can’t use Apidra in the t:slim because of how much heat the little pump gives off anyway, and now I’m wondering if out in exposed settings, it can overheat even Novolog (which has the highest temperature tolerance of the three RA insulins). Which would be bad, because with summer comes heat and we go to the beach every year for vacation and spend a lot of time outside playing there.

I only had switched back to the t:slim to be able to study my reports (because I can’t stand Diasend), but I’m thinking maybe if it can’t handle heat too, then what’s the point? I certainly don’t want to be switching out every two days either. And my reports? Well, they’re all screwed up to heck and back.. and what’s worse is I think it is because I put the pump to “sleep” back in March when I went on break from it and it messed up the pump memory (Tandem is looking into this).

I’m just baffled by this. I never had this issue with my Animas pump (which I’m strongly thinking of going back to and not looking back at all ever again).  I have plenty of stocked up supplies for my Ping, so I may as well switch back. I just hate how picky this t:slim pump is seeming to be for me. It’s really cool and I think they have  a great product, but it’s just not working out for me the more and more I use it. (Oh, and did you know the smallest basal rate you can set on it is 0.1? Not great for those who need tiny basals like 0.025u/hr.)

Have any of you other Tandem t:slim users had this problem??

One response to “Cooked?

  1. My son has the t:slim and uses Novolog. I have also wondered about the supposed heat that the pump puts out because we have, on occasion, had some unexplained bad numbers. I started believing that the higher numbers had followed us leaving the pump to charge for a couple of hours and that we cooked the insulin since a new cartridge resolved the issue. On the other hand, we have also had some bad numbers even though it was winter and the pump had not been charged. Again a new cartridge (and site – we do both) resolved things. Go figure!

    Most recently, we have had very hot weather and my son practiced lacrosse from noon to 2pm in the heat on Saturday. No problems to report on that cartridge. In fact we got an additional 18 hours from that cartridge due to the reduced basal (changed it yesterday instead of Sunday).

    Maybe your spike there is related to the effects of yesterday’s exercise finally wearing off.
