5 Equations for Calculated Values
This chapter contains the equations the PiCCO
2
uses to calculate the displayed values.
5.1 General
For the indexing of volumetric parameters the PiCCO
2
uses the following calculated parameters, dependent
on body characteristics:
BSA = Body Surface Area (m²)
Depending on the actual entered body weight (BW) different formulas are used for adult and pediatric
patients:
BSA = (BW
0.5378
x height
0.3964
) x 0.024265 Haycock, BW < 15kg
BSA = (BW
0.425
x height
0.725
) x 0.007184 DuBois, BW >= 15kg
PBW = Predicted Body Weight (kg)
Calculated according to height, gender and category
PBSA = Predicted Body Surface Area (m²).
Calculated with PBW instead of actual body weight (BW)
Calculation
Category
Gender
PBW (kg) = 50 + 0.91 [height (cm) – 152.4]
Adult
(habitus)*
male
PBW (kg) = 45.5 + 0.91 [height (cm) – 152.4]
female
PBW (kg) = 39 + 0.89 [height (cm) – 152.4]
Pediatric (> 152.4 cm),
(habitus)*
male
PBW (kg) = 42.2 + 0.89 [height (cm) – 152.4]
female
PBW (kg) = ((height (cm))² x 1.65) / 1000
Pediatric (< 152.4 cm)
both
*In marginal cases the decision about the correct category for the individual patient must be based on their anatomy and appearance
(habitus).
