Enter the macronutrient TPN (total parenteral nutrition) regimen and the patient's weight. It will quickly calculate total kcals/d, total kcals/kg/d, non-protein kcals/d, non-protein kcals/kg/d, protein intake (g/kg/d), lipid intake (g/kg/d), glucose intake (mg/kg/min), fluid intake (ml/kg/d), and the non-protein calorie to nitrogen ratio (NPC:N2) of your regimen. The full version includes three different data entry interfaces to choose from that emulate different methods for prescribing parenteral nutrition solutions: total nutrient admixture final concentration method, "safe practice position paper (JPEN, 1998)" method, and traditional volumetric-pharmacy method. Pop-up alerts regarding potentially toxic intakes of macronutrients in adult patients are included.
