Drug Calculation Definitions and Formulas
The Pump and Syringe Modules use the following parameters,
entered during the drug calculation setup procedure:
Bolus dose duration: Time period over which bolus dose
•
is to be administered.
Bolus dose units: Units used in calculating bolus dose.
•
Bolus dose units are selected from alternatives provided.
Diluent volume: Volume of fluid used as diluent for drug
•
(mL).
Dosing units: Units used to calculate continuous infusion
•
drug dose. Dosing Units are selected from alternatives
provided.
Drug amount: Amount of drug in
•
mcg, mEq, or units).
Patient weight: Weight of patient (kg); this is an optional
•
parameter that is not needed unless drug dose is
normalized for patient weight.
Time units: Time base for all calculations (minute, hour,
•
or day).
The bolus dose, drug dose, and flow rate parameters are
calculated using the above parameters, as follows:
•
Bolus dose = bolus dose x patient weight (if used).
•
Bolus dose administration rate (
When duration is entered = total dose / duration in minutes.
When Max Rate is used = Max Rate /
•
Bolus dose duration = bolus
•
Bolus dose
= bolus dose / drug concentration.
VTBI
•
Bolus rate = bolus
•
Continuous drug dose = flow rate x drug concentration
(normalized for patient weight if specified by entering a
patient weight).
•
Continuous flow rate = drug dose / drug concentration
(normalized for patient weight if specified by entering a
patient weight).
•
Duration =
/ rate.
VTBI
•
Drug concentration = drug amount / diluent volume.
•
Rate =
/ duration.

WARNING
The Drug Calculation feature is to be
used only by personnel properly
trained in the administration of
continuously infused medications.
Extreme caution should be exercised
to ensure the correct entry of the
