Parenteral Nutrition Calculations

_____________________________________

This video provides you with a step-by-step process for calculating parenteral nutrition.

You will learn how to the estimate nutritional needs for a patient, determine the grams and volume for each macronutrient, and how to write a prescription.

Remember, parenteral nutrition is intravenous nutrition!

There are several types of parenteral nutrition like PPN, TPN, 2-in-1 bags, 3-in-1 bags, and pre-mixed formulations.

This video just gives you the basics of figuring out the composition using macronutrients.

In future videos, I will talk about the different types, how this influences the composition, and how to determine the micronutrient composition. So subscribe and stay tuned!

**NOTE**

When discussing grams of carbohydrate per day, I say “1,400 minutes” on the audio, but the screen says “1,440”

1,440 is the correct number.

God bless you so much.

I have my exam tomorrow and thanks to your lecture, I can proudly solve anything about TPN

Thanks from my heart!
It is really an amazing video. I just watched this and understands the writing of TPN.
Thanks again.

Awesome video, I have no had to work on TPN in years and this helped me understand.

[anammirza]

Thank u so much, till now no one can made it easier like this for me. Thanks again

[kitashoe]

Thank you very much for this extremely helpful video
I'm still having trouble computing for PN but with this video I'm slowly understanding it

[avencomstock]

Do you have more examples with answers? I'd love to practice on my own and check my answers

[jissellerenee]

Maybe I’m missing it, but can you explain how you got 474mL H2O and how does this make up for the difference? Thank you!

Also, is it generalized to use the <5mg/kg/min for CHO? I was never taught this method!

[deannaj]

Where did the estimated 35 cc/kg amount come from? how was that number derived as well as the estimated energy requirements?

[salh]

thank you for this helpful and easy video illustration however, what if the bag used 3 in 1 .. how to start the feeding and increase gradually if all the solution is all in one bag ?
