Calculation of Protein Content Previous Page | Next Page

To calculate the grams of protein supplied by a TPN solution, multiply the total volume of amino acid solution (in ml*) supplied in a day by the amino acid concentration.

Note:
If the total volume of AA is not stated in the prescription, you can calculate it. Just multiply the rate of infusion of AA by 24 hr.

*Remember that 1 ml = 1 cc.

Example Protein Calculation
1000 ml of 8% amino acids

1000 ml x 8 g/100 ml = 80g
