I don't know over what time frame you are doing the testing, but you
need to get data every hour or so. It can be on different nights but
you must stagger the test times so you can develop an overlapping
data set. The finer data set must be collected using the same basal
rates on each collection run. The purpose is to make sure there are
no hidden lows/highs and to provide enough data to accurately set the
basal. The data set should be normalized to the starting bg of the
first data set. Make sure that she has fasted for at least 5 hours
and no boluses prior to starting the test period. Don't try to do it
2 days in a row, it is to hard on the 'victim' and will mess up the
data collection. Allow at least 1 or 2 days of rest. The basal rate
will probably not be flat as you have set it. Try to keep within the
not less than 70, not more than 170
70, you are headed too low. However, if you know her carb/bg ratio
fairly accurately, you can still get meaningful data by bring her
bg's up into the 120-150 range with glucose tabs and adjust the
subsequent readings by the shift produced by the glucose.
Over 160 or so, healthy kidneys spill glucose easily and will lower
the bg's more than you might expect, thus perturbing the readings.
This can take a while for a child. They don't necessarily tell you
when they are too tired or don't feel well enough to do it. I allow 2
to 3 weeks to get a pair of good data readings from Lily and she is
14 and communicates her physical feelings/wellness tjo me fairly
well. Profiles for days are a snap and can usually be collected in a
day or two unless the bg's stray.
Be patient, get good data. I will help you with the data reduction if
you wish, just copy the data to me.
Need to collect.
Kind of insulin and mix ratios if applicable
Time of last food
Time of last bolus
All basal rates from at least 2 hours prior to bg test start time
until test end time.
Bg's every 2 hours max (may be taken over several days)
With this info, you can make a reasonable prediction of where the
basal rates should be set.
I am cautious. I have checked Lily every night between 2 and 3 for
almost 4 years with only a few misses. It is our 'midnight meeting'
It is necessary as her basal rate triples at 1:00 am and a timing
mishap usually puts her bg's over the edge (usually a little high
thankfully). She's rock solid from 2:00 until anytime in the morning.
As her body changes and she matures, you can expect little suprises
like this from your daughter as well. They are nice and stable for
the longest time then bang, everything changes, then is settles down
My guess is that you need to shift 1 or more times during the night
between 0.2 and 0.3.
Try the basal projection tool on the HOWTO web page
This will assist you in estimating the necessary basal rates.
Use the tool to produce flat bg's, don't worry about the absolute bg
reading, only the flatness of the curve.
If you like, I will be happy to assist you with the data reduction
but will be away on vacation next week. Email me the data if you
