Mathematical Formula & Logic
Step-by-Step Worked Calculation
Scenario: Blood volume for a standard male
Calculate predicted blood volume for a male: Height = 1.80 meters, Weight = 80 kilograms.
Step 1: Identify inputs. H = 1.80, W = 80, sex = Male.
Step 2: Cube height: 1.80³ = 5.832 m³.
Step 3: Solve formula: Volume = (0.36693 * 5.832) + (0.03219 * 80) + 0.6041.
Step 4: Compute terms: 2.1399 + 2.5752 + 0.6041 = 5.319 Liters.
Step 5: The estimated blood volume is 5.32 Liters.
