Estimation of Body Surface Area

* use corrected body weight (CBW) unless actual body weight (ABW) < ideal body weight (IBW), then use ABW

Ideal Body Weight (IBW) Estimation:

Females:

IBW (kg) = 45 kg + 2.3 (# inches > 5 feet) OR

IBW (kg) = 48.67 kg + 0.65 (ht in cm - 152.4)

Males:

IBW (kg) = 50 kg + 2.3 (# inches > 5 feet) OR

IBW (kg) = 51.65 kg + 0.73 (ht in cm - 152.4)

Corrected Body Weight (CBW) Calculation:

CBW (kg) = (TBW + IBW)/2
