Start an infusion of nitroglycerin at 10 mcg/min, then
titrate to chest pain. The nitroglycerin is to be
mixed as 50 mg in 250cc of D5W. Use the
example below to see how to plug the numbers into the calculator.
In this example, the nitroglycerine infusion
will be set to 3 mL/hr.
Formula
First, convert mcg/min to mg/hr.
For example, 10 mcg/min becomes 0.6 mg/hr.
Next, solve the rest by using the IV
dosage formula.
In the example given, 0.6mg is the dose ordered,
50 mg is the dose available,
and 250 mL is the volume available.
If you're lucky enough to have new IV pumps
that accept mcg/min, obviously this entire process is unecessary.
