19. Calculation of dobutamine infusion in mL/hr
Step 1:
Desired dose = 20mcg/kg/min
Patient weighs = 155kg
Volume = 250mL
time min/hr = 60
Available strength of dobutamine = 500mg
To convert into microgram divide by 1000
Available strength of dobutamine = 500000
Step 2:
By substituting the values in the above formula,
Infusion rate = 93mL/hr.
The dobutamine should be infused at a rate of 93mL/hr.
20. Levophed Dose calculation
Step 1:
Levophed Dose strength = 4mg
To convert microgram, divide by 1000 = 4000mcg
Rate = 25mL/hr
weight = 136.4lbs.
To convert the weight into kg, divide by 2.2
then weight = 136.4/2.2 = 62kg
Time (hr to be converted into min) = 60
Step 2:
By substituting the values, in the above formula
Dose = 26.88 mcg/kg/min
The patient is receiving Levphed of 26.88mcg/kg/min.
