# how many gtts in a ml?

1. I am at work, and i have a pt with a chylis (doesn't happen often). I am alone (no other nurses) and i need to know jow many gtts in a ml, it is infusing at 16gtts per min, i want to write how many ml per hour. there is no set rate, it is palliative care.

thanks, i know this is a dumb question!

3. nurse_bride,
It all depends on your tubing. Most IV tubing is 10 gtts/ml, but peds is 60gtts/ml. Check your packaging and it should tell you.
Good luck, sorry you are working by yourself!

4. i know, but what is the formula? i am on night shift alone, sucks!
5. never mind, duh!!! i figured it out
drop factor is 10 per ml
6. 4-5gtt's = 1 ml 60gtt's = 5ml not agreed to accuracy-- 1 minim = 1gtt , not exact.
7. What is a gtt? I know a minim as an archaic unit of measurement.
8. Back in the 1980's when I went to school

1ml (or 1cc) = 15-16 minums.

0.06 ml = 1 minum = 1 gtt [gtt stands for "drop"]

:kiss
9. Thank you, I think! but how does "gtt" get to be "drop"? sorry to be so thick!
10. cheerful, I stand corrected-(-no use = forgetting) gtt= gutta, a drop.God I hate to be misstaken in calc's--one of my strong areas---well , the memory is the 2nd thing to go!!!!

I've heard that, too. But I never quote it, because some jerk ALWAYS asks what the first thing to go was, and I can't remember!!!! I mean, that's a joke, isn't it? But I really can't. It was either close vision or knees.

12. ok, here's the rule, imho the simplest way to remember.

first, what is cc/hr? if you are using micro-tubing, you're in luck--cc/hr = drops/min with micro-tubing (tubing with drop factor of 60).
(drop factor is the number of drops from this tubing that = 1 cc.)
if drop factor is 15, divide cc/hr by 4 for drop/min.
if drop factor is 10, divide cc/hr by 6 for drop/min.
:spin: yer home free! :spin:
13. If you set it on a pump it will be 60 gtts a minute regardless what tubing you put in. :-)

Cheerfuldoer I haven't seen that formula since nursing school gosh! :-) Bringing back pharmacology memories!!!!!
14. If you set it on a pump, why would you count the drops? I don't mean to sound rude or anything, but I thought we were talking about drip rates because the IV was not on a pump, just a roller clamp to adjust.
