Gina, you might want to call Medtronic and let them know. It seems like there should be a setting on the pump to alarm if it hasn't given insulin in a certain amount of time or stays in prime mode for too long. Even if not, they should know you experienced this problem as they could consider it for something to fix in the next pump! (Speaking as someone who works in the medical device industry, we WANT to know when patients have problems!)
Hi Gina I feel your pain, I just had something like that happened to me on Sunday, I had just been wearing the pump for 3 days, but I have been type I for over 16 years, and never felt as bad as this past sunday. I changed the site on Sunday afternoon then went to a game of golf but didn't take with me any supplies or even the glucose monitor, so between 5 and 10 I didnt receive any insulin at all, of course my pump didn't alert me of anything, it looked like it was getting delivered, there was no insulin coming out of the injection site and I could see the insulin moving on the tubing. Anyway by 12am I was at 600!!! It was impressive!!! I had to give myself a shot of Insulin with my syringe and figure out what was happening, changed the site and took almost all monday to get back to normal. It was terrible, I wish you could tell if the injection site is ok or not and not have to wait hours to find out.
