                                According to a 2023 StatPearls publication, protein requirements for critically ill patients can be as high as 1.5 g/kg/day, a key factor in determining the overall nutritional plan. A standardized approach is essential, and understanding what is the formula for calculating TPN is the first step in creating a safe and effective total parenteral nutrition solution.
