Quickly calculate estimated blood volume (EBV) for various patient types, including adults, children, infants, and neonates. An essential tool for medical professionals assessing fluid status and blood loss.
Formula:
The Estimated Blood Volume (EBV) is calculated using the following general formula:
EBV = Weight (kg) × Blood Volume Factor (mL/kg)
Where:
- Weight (kg): Patient's body weight in kilograms.
- Blood Volume Factor (mL/kg): An approximate value depending on the patient's age and sex:
- Adult Male: ~75 mL/kg
- Adult Female: ~65 mL/kg
- Child (1-12 years): ~70 mL/kg
- Infant (<1 year): ~80 mL/kg
- Neonate (<1 month): ~85 mL/kg
Note: These are average estimates; individual blood volume can vary significantly.
