Manufacturers may change an enteral nutrition formulation at any time. Nutrition information is kept as updated as possible, but it is recommended to check this data against the formulation at your local site. If you see a discrepancy, please contact us.

About This Calculator
How many calories is my patient getting?
This calculator is intended to provide clinicians with a 'snapshot' of a patient's existing enteral and parenteral nutrition status. Rather than providing a recommended nutritional regimen, this evaluation and analysis tool will summarize a patient's nutritional intake as it relates to total calories, macronutrients, fluid, and weight-based nutritional metrics (eg, protein per kg, kcal per kg, etc.). In its simplist form, it answers the question of "How many calories is my patient getting"?
If you are interested in calculating a new regimen for a patient, please see the TPN Macronutrient Calculator or Enteral Nutrition Calculator for dosing recommendations.
Nutritional weight calculation
In obese patients, this calculator uses a correction adjustment of 25% (see equation below); however, it is important to note that a higher correction coefficient (ie, 50%) may be appropriate for patients on chronic enteral or parenteral therapy when the goal is to provide full calories.2
$$\\ Nutritional\;weight = IdealBW + 0.25*(ActualBW - IdealBW)$$
Macronutrient Caloric Density
The following macronutrient caloric density are used for calculations:
| 9 kcal/g |
3.4 kcal/g |
4 kcal/g |
Osmolarity calculation
An osmolarity calculation may be useful for determining whether a patient's TPN requires a central line (>900 mOsm/L) or if it may be infused via a peripheral line (eg, "peripheral parenteral nutrition", or PPN).3 Note that the osmolarity calculation included in this calculator does not account for electrolytes, which will significantly contribute to a formulation's osmolarity.
