_CalculateBSA

Calculates the body surface area.

Syntax

_CalculateBSA(height,weight)

Parameters

Parameter	Definition	Data type
height	Height of the subject, in centimeters.	Float
weight	Weight of the subject, in kilograms.	Float

Returns

Body surface area (Float).

Notes

• Calculates the BSA using the following formula:

      (Float) (0.007184 * Math.Pow(height,0.725) * Math.Pow(weight,0.425));

  (Math.Pow is a method that raises a value to the specified power.)

• Height is assumed to be in centimeters, and weight is assumed to be in kilograms.
• Oracle recommends that you include rule logic to clear the calcualted value if a referenced item value is cleared. For example, if a rule calculates BMI based on the values entered in the Height and Weight items, the rule should clear the BMI value if the data in the Height item is deleted. For more information on appropriate rule logic, see Sample data-entry rules that use methods.
