I recently switched from a Paradigm 512 to a 522, and have noticed something weird with the temporary basal feature. I'm wondering if other users can confirm or deny my observations.

I set my temporary basal (TB) as a percentage of my "normal" basal, rather than in units/hour. If I set a TB using percentages, I cannot edit the percentage or duration once it has started. I must cancel the TB, and start a new one at the new percentage or duration. Now, it makes sense to me that I can't edit my normal basal, since that's what the TB is being calculated from. But I can't edit the TB duration?!?!

Minimed says that this is normal, but, for the life of me, I can't understand why they'd do this. FWIW, my 512 would let me edit the duration "on the fly", although IIRC, I couldn't change the percentage.

Has anyone else dealt with this or figured out a way around it? I'm hesitant to use units/hour for TB, simply because my rates change throughout the day, and I'd prefer to not have to reset the TB to account for every time my normal rate increases or decreases.

Thanks in advance!

I use the percentages for temp basals. Rarely do I go in and need to change it while its still running. Your right though, you can't go in and change it once it's going unless you cancel the first one. This isn't really a problem for me though. I suppose it could come up with a message saying "override current temp basal of x% for y minutes?" to which you'd have to accept and then continue.

Thanks for your reply. It's not often that I have to change the TB %, but I frequently find myself in situations where I need to extend the length of the TB.

I've found that also, but not having had the 512, with that feature, it hasn't bothered me to *not* have it. When I want to change either the % or the time, I just cancel and reset. Strange that they'd change it.

I have the 722 which I believe is identical to 522 apart from capacity. I can confirm that % temp basals are "uneditable" once set.

I didn't realise you did get more options if you set the rate rather than percentage, is that true? Although, like you I would only want to use percentage, especially considering my complex basal pattern.

I did have a few thoughts about how it was inconvenient to have to cancel and start again any basal change. But I suppose I shruggd that aside. If you previously had it better, it would be more frustrating.

Editing would be good. What I would also particularly like would be a DELAYED temp basal, for example if you are exercising and know you need one to start in 2 hours for a few hours (as I often do).

I also wish you could tell it to keep temp basal settings intact after pausing or other "interrupting" events. If there is a long term temp basal in place and you suddenly have to change your reservoir, I don't understand at all why it should be automatic to cancel the temp basal. This has caused serious interruption to my pump use at times, especially as it's easy to forget where you are up to in a longer temp basal, and once it's gone the info is gone.

Little niggles like this and more are making me start to think seriously about moving pump brand if/when I get the opportunity.

The 522 has a choice of Basal Patterns. A standard basal, "A" basal and "B" basal. You can set a pattern that is a % of your standard basal and go to Basal Patterns, use the alternate as long as you want. An open circle shows up on the screen to indicate you are in an alternate pattern.
Does this make sense?
