question about hourly rate of infusion
by Paula
(PA)
A bag of saline with an infusion apparatus is labeled 15 gtt/ml. The flow rate is 60 gtt/min. What is the hourly rate of infusion?
Help! Is this the formula to use? F = V/T Then solve 15/60 ? I am really stuck on this one. Thanks so much.
Reply (keith) : I'm not sure what formula you're trying to use there? I have a feeling that trying to put a formula on it may be getting in your way. Let's just look at it in practical terms...
O.K., so in this case:
You know that every minute 60 drips will drop
You also know that each time 15 drops fall = 1mL
So, how many mL are infused in one minute?
60 Ã· 15 = 4mL per minute
How many minutes in 1 hour?
60 (min) X 4 (mL) = 240ml
Formulas are great and you need to learn them eventually, but sometimes while learning it's better to just work it out on paper. Thanks for the question.
