HI Guys! I am so relieved - the pump is OK, it was actually a programming error. It's hard to explain, but the pump did change to the appropriate insulin to carb ratio - BUT - we have several preset buttons - that's the part that is hard to explain but here goes.
For example, when you dial in the number of carbohydrates that you eat, the pump goes up in increments of 5's. So if you ate 70 grams of carbs, you push a button that goes to 5, then you push it again and it goes to 10, again to 15, again to 20, again to 25, and so on all the way to 70. It is tiring to push the button all the way up to 70 and you can just imagine how annoying the button pushing is when you eat 150 carbs (which isn't very often, but if you have pancakes with syrup, it will be 150 carbs). So, there are some preset buttons on the pump. There is a 50 preset and a 75 preset - so that you go up from there, e.g., if you eat 75 carbs, you only push the one preset 75 carb button. If you eat 80 carbs, you push the 75 preset button and only have to push the button once more to go up from 75 to 80. He also has a "cookie" button, where you just hit cookie and it dials in 25 carbs, which is the average carbs in a regular sized cookie. There are a few other present buttons for other things. OK, so here's what happened.
We changed the insulin to carb ratio on the pump - but we didn't change the ratio on all the preset buttons. Now, I can plead ignorance, I thought if you changed the ratio on the overall pump settings, it changed it on the presets too - but it does not, you have to change the insulin to carb ratio on all the individual presets also. Yes, the nurse 3 months ago and the nurse yesterday should have done this - but they didn't. I'm glad I figured out the problem and I'm glad it is fixed now!
The moral to the story - don't rely exclusively on machines. If I had just once, in the last 3 months, hand calculated his insulin to carb ratio, I would have caught this error before yesterday.
Oh well, it's fixed now. YAY!
