Pediatric Blood Volume Formula
The estimated blood volume (EBV) for a child is typically calculated based on their body weight and an age-specific blood volume factor. The formula used is:
Estimated Blood Volume (mL) = Child's Weight (kg) × Blood Volume Factor (mL/kg)
Where:
- Child's Weight (kg): The weight of the infant or child in kilograms.
- Blood Volume Factor (mL/kg): An estimated value representing the milliliters of blood per kilogram of body weight, which varies by age group:
- Premature Infants: ~90-105 mL/kg
- Term Neonates: ~80-90 mL/kg
- Infants (3 months - 1 year): ~75-80 mL/kg
- Children (>1 year - Puberty): ~70-75 mL/kg
