Goal

• Replace fluid lost
• Meet maintenance requirements

8
Calculate Dehydration

• Multiply dehydration by body weight in
  Kilograms
• 5 x 50 kg 0.05 x 50 kg 2.5 kg
• 2.5 kg 2.5 Liters
• This is the fluid deficit

9
Calculate Daily Maintenance

• 0.06 Liters/kg/day
• 0.06 x 50 kg 3 liters
• This is the maintenance requirement

10
Total Requirement

• Fluid Deficit daily requirement
• 2.5 liters deficit 3 liter daily requirement
