    You will need to consider the percent of enteral fluids or feeds and the percent of TPN. For example, a 1.0 kg baby on 100 ml/kg/day of TPN and 25 ml/kg/day of feeds is receiving about ¾ TPN and ¼ enteral nutrition (EN). The TPN should reflect this proportion. Protein, lipids, and electrolytes should equal about ¾ of the total nutritional .

    Calcium and Phosphorus - Parenteral Nutrition

    Calcium and Phosphorus. An optimal ratio of calcium-to-phosphorus intake is 1.7:1 (by weight) or 1.3:1 (by molar ratio). In situations of fluid restriction, however, high concentrations of calcium and phosphorus may cause precipitation within the solution. These calcium-phosphorus complexes may cause phlebitis and life-threatening emboli.
