So all the literature..and lectures says to change sets no longer than every 3 days 1, 2,, day three it comes out and a new one does this mean:


If I put an infusion set in on Tuesday--that it comes out and a new one goes in on Thursday---or do you count 3 days?

I'll go 4 days, counting each 24 hour period as one day, as long as the site is not hurting and numbers are good.
Fist of all, day 1 ends when the first 24 hours of pumping through the site ends and day 3 ends and set change would occur when 72 hours have past since inserting the set. So in on Tuesday out sometime of Friday - does not have to be exactly 72 hours.

Secondly, there is no rule that says you must change your set when your reservor is empty. I try and change my insertion set every 72 hours - do not always wait that long as sometimes I find the set leaking at about 60 hours as a result of tunneling. Due to my insulin use I need to change the reservor about every 50 - 56 hours. So I do not change both at the same time.
I count mine as hours. As I use Sure-T's the recommended is 2 days. I count 48 hours from the time of insertion, to the next change.
I go 3 days only b/c my skin is sensitive and will get a rash, and I find the Humalog really poops out after a few days, so its better to change before that happens. I end up wasting a lot of insulin. Your time scale was right, if you put a set in Tues, you would best change it Friday.
Good luck!
Since I am on CGMS, I usually change my infusion site when I change my sensor. Anywhere from 3-6 days usually. If I put a new one in on a Monday, I count 3 days ahead (which would be Thursday) and that is 3 days for me.
Good luck and much success in managing your diabetes:)
A day is 24 hours. So if you put the infusion set in on Tuesday afternoon, day 1 ends on Wednesday afternoon, day 2 on Thursday afternoon and day 3 on Friday afternoon. To me, it doesn't make sense to count a couple of hours as a whole day. When I first received my pump back in August 09, the diabetes educator helped guide me through my first infusion application and told me to come back in three days so she could help guide me through the change. I received it on Monday morning; the appointment she made for me to come back was Thursday morning-- 24 hours X 3 = 72 hours. Putting it in on Tuesday evening and taking it out on Thursday evening is only 48 hours, hence only two days. I sometimes keep the set in for 4 days if all is well-- i.e.-- no itching or pain or redness. I change reservoirs when my insulin is low-- down to 6 - 10 units and simply reuse the tubing, which I attach to the new reservoir. Again, my diabetes educator told me to do that. It's worked well for me. Luckily, my Humalogue has never lost its strength, either in my pump, or in my cupboard when I was on MDI for years. If I get highs, it's because I've miscalculated carbs, I'm coming down with something or I'm already sick, or my infusion set isn't in properly. (That's only happened a couple of times, now that I'm much better at using the inserts.)
