IV drip formula


0Dec 19, '12 by akulahawkRN, ASN, RN, EMTPQuote from SweetPEIThis is a great method... just make sure that you set the problem up correctly and it works, every time. I personally could never quite wrap my head around it, but I know how to do it. Everything I've had to do to date has been either a simple math problem or a ratio problem. There are lots of sites out there for med math. The one above "DosageHelp" is really a good site for that stuff.Dimensional analysis works great for me

1Dec 19, '12 by Roshni69A very simple formula that i use
Fluid divided by time multiplied by drop factor it will be as
Fluid'/. Time * drop factorpaigewhitten1991 likes this.

100ml/ over 60 minutes x drop rate (usually 1315) 
0Jan 1, '13 by BajanCherryOk I used the ml x gtt / time... Works great to get your gtt/min... now my question is how do I solve the units/hr, mLs/hr, and how many hours with the IV pump run for.... I've tried different equations and I am LOST!
I am trying on my own until class starts and I go to tutoring.... 
0Jan 2, '13 by Michaela, RNI still use the mlxgtt/time... then to find units/hr just multiply gtt/min x 60min. To find mls/hr just do ml/60min

0Jan 2, '13 by GrnTea, BSN, MSN, RNI always tell students that they can use whatever formula they like best (I'm not sharing mine here), but if you have a rough idea of what it ought to be, you can recognize a totally offthewall wrong answer.
To address this question: Your units or milligrams or widgets per hour you solve by first knowing how many units, milligrams, or widgets there are in a given volume. Your problem will always give you the information you need to figure that out.
For example, if you have a solution that is 500,000 widgets per liter, then you can figure out how many widgets per cc here are, right? 500,000 in a liter / 1000cc in a liter.... so 500,000/1000 will tell you that. So you have 500 widgets in a cc. If your problem asks you to give 25,000 widgets per hour, how many cc is that? That would be ... fifty cc.
