One math prob that could help please regarding infusion rate

Sorry my maths equation didn't save very well, but I think you know how I mean to set it out! Also round up/down your answers to the nearest whole number.

There is really not a whole lot of need to memorize anything but the formula to figure out flow rate, in this situation. If you have 500 cc going in over 4 hours,

you will follow the formula to figure out flow rate which is:

Volume to be infused divided by time in hours. (That is your key... So 50 cc divided by 30 minutes would be 50/0.5, or 100cc/hr)

Then, once you have flow rate, as a previous poster alluded to,

use the appropriate equivelant to divide into your volume..i.e.

If your tubing is a macro gtt tubing and allows for 10 gtts to infuse per ml, then think of a clock.

How many 10 second increments are their in a minute? The answer is 6. Divide your flow rate by 6 and you'll get gtts per minute.

If your tubing is 15gtt/ml. There are 4, 15 second increments in a minute, so divide your flow rate by 4.

20 gtts/ml tubing = divide by 3

And mini, or micro gtt tubing (60gtts/ml), divide your flow rate by 1.

Hope that makes things clearer.

i have been using google but just wanted help getting on track with one math problem, i don't appreciate you being so condescending

it would be a little nicer to use the quote feature so as to clarify who you are addressing this entry to as the majority of responses seem to be trying to help.

Formula is always:

Volume to be infused

_________________ X Drop factor (gtts)

Hours (into minutes)

So your equation would be

500 divided by 240 (there 240 minutes in 4 hours) multiplied by your drop factor of 15.

It comes out to 31.25, but you obviously can't have "quarter of a drop" so you round it down to 31.

If you meant me.......?

I did not mean it as being condescending...........sorry you took it that way I think the LMGTFY is a riot........no sarcasm meant xo:)

I love it! Had no idea that URL existed, how funny.

What does LMGTFY mean?

:hhmth: I am currently studying for my NCLEX... I soooooooo needed that laugh!!

I am literally bent over in hysterics!! Too funny!!

=)

It's the link to Let Me Goggle That For You http://lmgtfy.com/ It's hysterical!

Oh yeaaaah. I didn't know about it, but I am planning to wear it out.

I used the dimensional analysis. For me it never goes wrong.

gtt/min= 15gtt/mL X 500ml/4hrs X 1 hr/60mins= 31 gtt/min

Everything cancels out and your only left with gtt/min and that how you know that you set it up right. Hope this helps.
