Insulin pump Flashcards
Correction insulin –
TDD - Total Daily Dose
ISF - Insulin Sensitivity factor
ISF = 1500 / TDD
1 unit of novolog will decrease ISF
—– example
TDD of a patient is 50
1500 / 50 = 30
Correction will look like this
- < 150 no insulin
- 150150-179 1 unit extra
- 180-209 2 units
- 210-239 3 units
- 240-269 4 units
Meal time insulin
ONE time correction calculation
ICR = Insulin to Carb ratio
ICR = 450 /TDD = (1 unit insulin per gram Carb)
One time correction = Glucose - 150 / ISF
Starting Insulin in DM Type 1
Starting Insulin in DM Type 1 Depends on various factors; coming off an insulin drip or not Usually:
- ( body wt in kg ) x ( 0.5 ) = TDD of insulin
- (100 kg) * .5 = 50 TDD
Basal amount
- ( TDD ) x ( 0.5 ) = starting Lantus dose
- 50 * .5 = 25 units of lantus
Correction amount
- 1500 / TDD = ISF (insulin sensitivity factor) to setup novolog correction
- 1500 / 50 = 10 (everu 1unit to correct 10 Glucose levels)
Novolog with meals ICR
- 450 / TDD = ICR (carb ratio) to set Novolog mealtime insulin
- 450 / 50 = Insuline to carb ratio of 9
Converting to U 500 insulin
it is 5 X more concentrated.
TDD = 220
Convert to U 500 = 220 / 5 = 44
Will reduce to dose by 30%
44* 0.70 = 30 units U 500 TDD
