IV Drip Rate Formula


Feb 5, '05Quote from mel82To calculate drops per minute:Does anyone have a simple Iv drip rate they would care to share?
Thanks
total volume x drop factor(on the tubing)
__________________________________
total time in minutes
Calculate ml/hr:
total voume in ML's
________________
total time in hours
To calculate ml\hr when infusion time is less than one hour:
total volume x (mL/h)
________________ = __________
total time(minutes) 60 minutes
I hope this helps 

Feb 6, '05Drops over time times ml = gtt/min
I always think of a drunk to remember this, like a drunk with DT's 
Feb 6, '05vd/t (volume x drop factor/ time)
That's how I remember it! At the same time we were learning this formula I had to prepare a presentation for my clinical site on STDs and a lot of patients still referred to them as VDs. So that formula REALLY stuck in my head after that. :chuckle 
Feb 6, '05To get drips per a mininue first find out what it is for ml/hr:
1.) volume/given hours
2.) hourly volume/60 x drop factor 
Feb 6, '05If the worst happens and you can't remember the formulas, you can set up a ratio & proportion to solve most anything;can go from total ml, to ml/hr,to gtts, if all else fails.

Aug 14, '08I'M WORKING ON A PROBLEM. How to U calculate the total ml's if U only have gtt/min gtt factor, and # OF HOURS TO RUN?
