Description

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

Other Equations

For men:

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

For women:

plasma volume = 1278 * ((BSA in m^2)  ^ (1.289))
