IV rate formula's any easy ways to remember?
- 0Jan 8, '08 by critical thinkerDoes anyone out there have any idea's on how to remember the IV rate formula's? Second semester starting on Monday, and these calculations will be our first test, I would like to find an easier way to remember them. Thanks.

is that the formula you are talking about?
It is just a matter of getting the end units to what the question is asking for, there isn't much to memorize. It is all just manipulating numbers to get the right units. And making sure it all makes sense!

there are iv calculation problems and tutorials on post #6 of this thread:

Once the equation is "built" you cross check to make sure all of your units cancel. If you end up with the units you are looking for (such as gtt/min) then you know you have built the equation correctly. Then...you are left with some simple multiplying and dividing. If you had your units correct in the set up...your pretty much assured to get the final correct answer.
Approach pharmacology math as a skill...the only memorization you should do is your unit conversion fractions.
