Notes about the Advanced Option:
•
The calculator estimates the amount of rapid-acting insulin still in
the body and how much longer it may be active . The active insulin
estimate is calculated from the set insulin duration, the time, and
amount of the last logged rapid-acting insulin dose .
•
Both meal and correction doses are included in the active insulin
tracking .
•
Insulin doses calculated 0-2 hours after a previously logged dose
will only include a meal dose . Active insulin will not be subtracted
from the meal or carbohydrate dose, and a correction dose will not
be included even if the blood glucose is outside the target . During
this time period, the previous dose has not reached peak action and
additional correction doses, referred to as `insulin stacking' , may result
in hypoglycaemia .
•
Insulin doses calculated between 2 hours and the set insulin duration
will have active insulin subtracted from the suggested dose (for
example if insulin duration is set at 5 hours, active insulin will be
subtracted from doses calculated between 2-5 hours) .
•
All previously injected rapid-acting insulin should be logged to ensure
accurate active insulin tracking and calculations .
