Note:

Individualised IVN is not to be ordered without approval from the specialist on duty.
Standardised solutions should be used in preference to individualised solutions, except in circumstances where nutritional needs cannot be met with the available IVN preparations.
- If the only difference between a standard solution and the requested individualised solution is that more sodium is required, consider using a standardised solution and run in a separate infusion of sodium chloride.
This worksheet is designed to provide a prescription for individually prescribed IVN.
Some features are built in to the calculator including a limit on protein, glucose and lipid intakes, and limits on sodium, potassium, calcium and phosphate.
The prescriber takes responsibility for the IVN prescription.

This ratio is calculated as if no enteral nutrition is being given
A ratio of 24-32 is thought to optimise anabolism
