Can I ask a stupid question, ive been on the Medtronic 640g for 2 months now. when I go to the gym my bg always rises so today I decided to do a temp basal for 4 hours after, my problem is I didn't understand how to do it in percentages. I thought my pump would have a minus and plus at the side. I ended up doing it by rate but everyone does it by percent. Sorry for sounding so thick but can someone explain percentages please
 
Your basically increasing your current basal rate by the % that you enter, so say your post-exercise basal rate is 0.5u and you increase it by 20% this would make your basal rate 0.6u for the next 4 hours.
 
Hi. I had the same problem as you about setting the % and how to set TBR after 9 months on Pump. BUT yesterday went back to my Clinic and was gratefully shown. I was injecting Levimir by my pen when necessary.

It depends on the pump. My current one has a + and - so I can increase it by, say, +30% or decrease it by, say. -50%.

I found this confusing at first and had to keep double checking as my old pump did it a different way - eg on that one, if I wanted to double my basal rate I simply increased it to 200%. If I wanted to reduce it, I could have, say, 80%. I found that much easier.

If in any doubt, check your pump manual. You don't want to decrease when you meant to increase or vice versa.
 
Standard basal - i.e. your usual pattern - is 100%. This is shown on my pump as 100%, so if I want to take less basal, I reduce it to 90, or 80% of my standard dose.
If I want to take more basal, I increase it to 110 or 150, etc.

I don't need to think of it as 'reduce it by 10%' or 'increase it by half' - it's all done for me by percentages.

Some of the other pumps I've seen do it differently - I have the Insight, and the way it does this (in percentages) appeals to the way I do my maths.
