3.1 Dosing Units and Dose Rate Calculation (Overview)
The following list shows the units used in the pump:
Gram family: ng, mcg, mg, g
Unit family: mIU, IU, kIU, MIU
Equivalents family: mEq
Mole family: mmol
Kilocalorie family: kcal
Millitliter family: ml, ml/kg
In addition to these dosing units the user can choose:
• Feeding: kcal, mEq, mmol
• Surface related amount units: m

The pump is calculating the body surface area with the “Dubois” formula
(DuBois D, DuBois EF. A formula. Arch Intern Med 1916; 17: 863):
BSA(m2) = 0.007184 x weight(kg)0.425 x height(cm)0.725.
Check plausibility of calculated body surface area value and resulting delivery
rate before starting the infusion, also, if body surface area related dose rate is
set by Barcode. The dose rate calculation enables a calculation of the rate in
ml/h based on the entered dose parameters.
Setting parameters:
1. Concentration as the amount of the active ingredient per volume.
- Amount of the active ingredient
- Volume in ml
2. Where necessary: Patient weight or Patient height
Note: - Patient weight can be entered in kg, lbs or grams.
- Patient hight is entered in m (is used to calculate BSA)
3. Dose prescription:
- time related as the amount of the active ingredient per min, h or 24h.
- time and patient weight related as the amount of the active
ingredient per kg per min, h or 24h or BSA.
4. Where necessary: VTBI in ml.
