Can somebody advise me what I'm doing wrong because I can't seem to get it right. At 5.40 today I was 14.3 so gave myself 3 units to get back in range. Then before breakfast at 7.20 I was 8.7 and slightly dropping. I had 30g of carbs so normally give myself 3 units but the pump was saying I still had 2.5 units on board so only gave myself 0.5 units instead to prevent going hypo. Have just scanned again now and I'm 12.6 and slowly rising. Did I do the right thing by not giving myself the full amount for breakfast or should I have done. I'm just getting so confused.
Hello - pumps aren't magical (well mine is as I've got a closed loop one) and are designed to take account of your active insulin when correcting a blood sugar. They will assume the life of this dosage to be 4 hours so your dose at 5.40 will have expired by 9.40 so your pump is designed to avoid panicked over stacking of correction doses which would lead you to a hypo.
Firstly I would say don't panic if you've gone to a 12 unless this persists for more than 2 hours?
If this happens then you'd need to look at 2 things:
Bolus to carb ratio
Correction dose ratio
If you've got the first thing right then the 2nd should not be necessary unless your background basal is off.
I am assuming that the ratio s etc were set up on your pump and that you know how to edit them if necessary?
At the end of the day the pump is a mechanical device and just does what you've told it to do and some days your body isn't going to behave as expected.
Also why did you wake up to test yourself at 5.40? If you've got an fsl alarm for highs it may be better to disable this at night time unless your blood sugars are very wild! Just the stress of waking up that early would spike me!!
