Ok pre meal ,say blood is 5.0 ,after 2 hours should it rise by 2.8 at the most ,and 4 hours later should be back to 5 ish is this correct ?
What if after 2 hours later bloods had dropped a little but still in normal levels ,is this ok or ratio wrong

Those figures seem about right, it's not an exact science. I wouldn't adjust ratio's with those levels. Well done.

If you come down to your pre-meal levels after 4 hours then your ratio is correct. Though the spike itself has little to do with your carb ratio and more to do with what carb you eat.
 
Your BG levels are up and down all the time so what you write is a 'rough guide'. If you were 5.0 before a meal and ate a meal of bacon, eggs, mushrooms and tomatoes and a first class proper meat sausage without cereal in it, you'd probably be less than 5.0 because the meal hasn't contributed any carbs.

However, if you did some exercise in that two hours and your BG fell to below 4.0 (approx), your body would give you a top up of glucose from its own sources such as fatty acids, and your BG would rise, possibly higher than 7.8. It depends on the time at which gluconeogenesis occured. But, that is a separate process and although your reading will reflect that process it would not actually tell you anything about your meal or your diabetes.

"Gluconeogenesis (abbreviated GNG) is a metabolic pathway that results in the generation of glucose from non-carbohydrate carbon substrates such as pyruvate, lactate, glycerol, glucogenic amino acids, and fatty acids (both even-chain and odd-chain) .... the process occurs during periods of fasting, starvation, low-carbohydrate diets, or intense exercise."
 
What target range is. Chloe using on the combo, is it 4 to 8mmol so.the target average is 6mmol. or is it different? By default the meal rise is set at 3mmol. 2.8. is a bit tight and will produce a lower bg before the 4hrs is up unless the target bg is also 5mmol when you do the basal testing and you set all the basal rates to keep bg at 5mmol. I use 6.5 as my targets

If blood lowers at 4 hours.. Then to me I would personally alter the basal rate so that you get a higher 4th hour result if on a pump.
As a general rule of thumb if on a pump if your levels rise 2-3?hours after a bolus then your bolus needs altering.
The only way to really check is to do a basal test and test every hour....

How do i do a basal test ?on the pump ? Theres a few times i feel i want to change basal but nurse is reluctant as for kids its programmed on a setting like a wave of what kids should be using at her age and so she lowers it all by a percent instead of individual hours

Basal testing is going without food basically for up to 5 hours and testing every hour to see what happens to bg levels.
However, its not as simple as that because any previous bolus must be out of blood as well, so that can effectivy be 10 hours without food.
You should not basal test if you have had a high or low in the previous 5 hours either.
With children, the HCP's may be reticent to do basal testing...,

Oh yes ok i understand now thats what We did it at night to test the night time one for weeks an thats spot on she stays between 4 and 8 all night .yes i cant imagine chloe fasting for 5 hours or more but could can imagine it would really help

Thats why it us imprtant for children (and parents) to know that it is 2-3 hors after a bolus that is bolus to amed, all others is basal rates to change.

You need to get to the point that blood levels change less than 2.8 ml 2hrs after a meal and during the night that they can remain between 5 and 7 ideally.

This isnt an instant thing. Can take months on a pump.. Then all of a sudden they'll be schoool hols!! Which can mean different rates.

It certainly isnt easy for a parent
