Meter accuracy (or lack thereof).
I think I speak for the entire DOC when I say it makes our collective butts itch. It still makes me want to scream that a 20% accuracy is acceptable.
The problem for those of us that have wee ones is that when a high number pops up on that ol' inaccurate meter, there is a greater margin of error.
Take, for example, what happened the other night. It was 1 am. Elise was 352. I decided to check again. This time 305. That's almost a 50 point difference!
And what does 50 points mean to Elise? Well, just for chuckles, I popped both numbers into the PDM, and there was a difference of .2o units of insulin. Not a big deal if you're an adult.
Kind of a big deal if you're 4 years old. When I did the math, I figured out that .20 units of insulin drops Elise by 50. Elise's target at night is 140. That means that if I corrected for the 352, Elise could end up at 90. Not a good number for the overnight. Me no likey.
And I'm not even taking into account the fact that Elise tends to drop at about 6:00 am, especially when she has received any sort of correction in the night (we're still fiddling with the numbers and trying to find what works). She has been in the 50s a number of times in the 6-8am time period after a correction that has taken place over four hours prior. If we don't have to correct her, it's pretty smooth sailing.
The problem as I see it is this; the higher the blood sugar, the more insulin you give. And the higher the number on the meter, the bigger the margin of error. To me, that's just dangerous when it comes to our tiny kiddos with D.
When I get a high reading, I shouldn't have to check again (as we all know, those suckers are expensive). And I shouldn't be worried that I'm giving Elise too much insulin, causing me to lie awake all night, fighting the urge to check her every 30 minutes. Shouldn't we be able to trust our technology?
For the record, I corrected using 305. And she woke up just fine.
