Question about correction factor on MDI and when to adjust it.

My daughter who is usually extremely insulin resistant is suddenly not. The last 2 days she has gone low at 2 hours after receiving her insulin and is very hard to get up. I am certain she has gotten a unit to a unit and a half more than she needed.

I'm trying to learn to do these adjustments myself.

Right now her breakfast ratios are BS-150/50 + Carbs/12

This was working but is clearly to much now.

How I know when to adjust the correction factor. I usually just adjust the carb ratio. To get the change I need I would need to change the carb factor to carbs/30.

Her other doses are BS-150/120 + Carbs/30 Lunch
BS-150/90 + Carbs/36 Dinner

 

Just try changing it, see what happens. Think about how much you think each unit lowered her.
But first it's a good idea to be fairly certain about what's happening with the basal- would she drop if you didn't correct her?

 

I would suggest talking to her Endo about all of this.

 

This is an unusual way of expressing carb ratios.

So maybe help us out here if you can:

1) How much Lantus does she get, and when?

2) Breakfast carb ratio is 1 unit for 12 carbs?
Lunch carb ratio is 1 unit to 30 carbs?
Supper ratio is 1 unit to 36 carbs?

3) Correction factors are 1 unit for every 50 over target (150) at breakfast, 1 for every 120 over target at lunch, and 1 for every 90 over target at supper.

4) She is 3. How much does she weigh?

5) About how many carbs on a typical day for breakfast, lunch, and supper?
