IV intake calculations...

We really haven't gone over how to calculate iv solutions yet. I'm assuming they believe it's instinctive or common sense in calculations. But I'm very lost. My pt was recieving d5w 40/ml per hour in a 1000 ml bag ( i believe) and a piggyback of piperacil of 2.25g with 50ml d5w infused at 100ml/hr.
How do i figure out the intake? 


Nov 13, '07Add up the mls for the hours you were there. So if you were there for four hours the 1000ml of D5W would have ran 160 ml. I don't know if there was any other fluid in the med piggyback but you would put the full 50 ml because this bag would have ran out in 30 mins.
Hope this helps.

The IV fluids: 40 cc/hour x 7.5 hours = 300 cc
The IVPB: 50 cc/30 minutes = 50cc
Total for 8 hours = 350cc IV intake

Nov 14, '07Quote from Suesquatchthanks, I guess I was thinking that the IV fluids would still be running at the same time...now that I think of it, if both the fluids and IVPB ran at the same time through the same line, the med would be diluted.Because the IVPB got 30 minutes.
Still a prenursing student, but loving this education! 
Nov 16, '07In the real world when you are figuring I&O... depending on what type of pump you have... there is a option to go in and see the total amount infused for that shift... the only problem is that people forget to clear the pump totals before the next shift comes... so you can't always go by it.
I'll give you a really simple way of doing this very quickly
First thing is the piggyback med... a total of 50 ml rate at 100... that means it went in over 30 minutes.
Now assume that we are working an 8 hour shift... minus the 30 minus for the med
Primary fluid was running at 40 ml/hr for 7 hours & 30 minutes.
40ml X 7.5 hr = 300ml of primary fluid
300ml + 50 ml of piggyback med = 350 for an 8 hour shift.
Good luck,
