The Maintenance Fluids Calculator calculates maintenance fluid requirements by weight. Based on Holliday-Segar method and the 4-2-1 rule.
This calculator determines the fluid requirement that needs to be corrected in pediatric patients based on weight (because total body water relies on weight). There are two calculation methods used, the Holliday-Segar nomogram and the 4 – 2 – 1 rule.
Holliday-Segar Formula for Maintenance Fluid Requirements by Weight / Holliday-Segar Formula for Maintenance Fluid Requirements by Weight. Weight (kg) Water. Electrolytes (mEq/L H2O and mmol/L H2O) mL/day. mL/hour. 0–10. 100/kg. 4/kg. Sodium 30. Potassium 20. 11–20. 1000 + 50/kg for each kg > 10. 40 + 2/kg for each kg > 10.
Maintenance Fluid Rate is calculated based on weight. 4 mL / kg / hour for the first 10kg of body mass. 2 mL / kg / hour for the second 10kg of body mass (11kg - 20kg) 1 mL / kg / hour for...
