Total Fluid Intake (TFI)
Calculates total fluid intake in mL/kg/day from all parenteral and enteral sources
Total Fluid Intake (TFI) encompasses all sources of fluid administration including IV fluids, enteral feeds, and medications, requiring careful calculation to ensure appropriate fluid balance in pediatric patients with impaired renal function or disease states limiting free water tolerance. This calculator helps clinicians integrate all fluid sources to achieve target total daily fluid volumes while accounting for sensible and insensible losses. Use this tool in children with chronic kidney disease, heart failure, or other conditions requiring fluid restriction to monitor cumulative fluid intake.
