Fluid Infusion Rate (4-2-1)

Minimum hourly fluid rate for children and adults
4 mL/kg times the first 10 kg, plus
2 mL/kg times the second 10 kg, plus
1 mL/kg for each additional kg equals appropriate IV infusion rate based on weight (e.g., an 80-kg patient would require 120 mL/hr).

Example: 1st 10 kg X 4 mL = 40 mL; 2nd 10 kg X 2 mL = 20 mL; each additional kg (60 kg left) X 1 mL = 60 mL for a grand total of 40 mL + 20 mL + 60 mL equaling 120 mL/hr for an 80-kg patient.
