Calculation of Protein Content

|

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   Practice Calculations
