convert mcg/kg/min to ml/hr
Dr. Smith wants a dopamine drip started at 20mcg/kg/min on John Doe in Bed 7. John Doe's weight is 70 kilograms. He wants an 800mg vial of dopamine mixed in 500 mL of D5W. Plug in the amounts in the calculator as shown below.

Using the calculator, John Doe's IV pump is set to deliver 53 cc/hr of Dopamine.
|(mcg x kg)||X 60|
First, convert mcg/kg/min into mg/hr.
In the example above, the dose would be 84 mg/hr.
|(20mcg x 70kg)||X 60||= 84|
Next, use the IV dosage formula to solve the rest of the problem.
|dose ordered||X volume available|
In the example, 84 mg is the dose ordered,
800 mg is the dose available,
500 mL is the volume.
|84mg||X 500ml = 52.5 ml/hr|
If you're lucky enough to have new IV pumps that accept mcg/kg/min, obviously this entire process is unnecessary.
