TPNcalculator

The TPN calculator by CKD Associates, Inc. was written by Dr. Andrew Lazar, a nephrologist in the Cleveland area. The product gives the health care provider an option for choosing total kcal/kg/day, g/kg/day protein, and the percent of total calories delivered as carbohydrates. The calories delivered as lipids is the portion of calories that remain, after considering the protein and carbohydrate calories. If the lipids toggle is turned off, the protein and carbohydrates can be adjusted upwards to make up for the shortfall.

The default concentrations for protein, carbohydrates, and lipids depends on the volume status chosen.
If hypovolemic: 8.5% Amino acids, 20% Dextrose, 10% Lipids
If euvolemic:10% Amino acids, 40% Dextrose, 10% Lipids
If hypervolemic:15% Amino acids, 60% Dextrose, 20% Lipids

Otherwise, the user can choose the Dextrose, Amino Acid, and Lipid concentrations for customization. When any keyboard is open, it will be closed by hitting any other location on the screen.

The total kcal/kg/day varies between 10 and 45 kcal/kg/day, protein between 0.3 and 2.0 g/kg/day, and carbohydrates between 40 and 80% of total calories.
