Correction bolus onlyCorrection bolus only
The mySugr Bolus Calculator always compares your blood
sugar result with the currently allowed target range, and not
just with the target value for the current time block.
Diagram 2 above shows an example: The first correction
bolus remains active during the acting time (the width of the
blue area). If a measured value falls within the currently
allowed blood sugar value (height of the blue area), no new
correction bolus is calculated.
55..77..22 Mathematical basis for bolus calculationsMathematical basis for bolus calculations
Below is a list of the most important formulas and principles
that the mySugr Bolus Calculator uses to calculate your
bolus.
Generally, a correction bolus is calculated only if your
current blood sugar value is above the hypo blood sugar
warning limit and outside of the target range. Additionally, it
must be above the currently allowed blood sugar value.
Only correction boluses greater than 0 will trigger an acting
time.
* Currently allowed blood sugar value = The blood sugar
value used in the calculation of a correction bolus, taking
into account time block settings (target range mean value),
currently active meals (meal rise), and currently acting
correction boluses (active insulin).
** Δ Blood sugar = The dierence between current blood
sugar level and target blood sugar level.
