If the Body Surface Area (BSA) is known, then the plasma volume can be calculated fairly accurately.
First, convert BSA into square meters. If in square centimeters, divide BSA by 10,000.
Second, determine patient's sex.
Third, perform calculation:
• if male: plasma volume in mL = (BSA in m^2) * 1560
• if female: plasma volume in mL = (BSA in m^2) * 1410
plasma volume = (BSA in m^2) * 1630
plasma volume = 995 * (e ^ (0.6085 * (BSA in m^2)))
plasma volume = (1580 * (BSA in m^2)) - 520
plasma volume = 1278 * ((BSA in m^2) ^ (1.289))
