Notes about the Easy Option:
•
The calculator estimates the amount of rapid-acting insulin still in the
body and how much longer it may be active (if the correction factor is
set to "no correction insulin", active insulin is not calculated) . The active
insulin estimate is based on a 4-hour insulin duration calculated from
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 2-4 hours after a previously logged dose will
have active insulin subtracted from the suggested dose .
•
All previously injected rapid-acting insulin should be logged to ensure
accurate active insulin tracking and calculations .
