What is the Rule of Nines?

The Rule of Nines is a method used in emergency medicine to quickly estimate the total percentage of burn area in adults. The body is divided into sections of 9% or multiples of 9% (head and neck 9%, each arm 9%, each leg 18%, front torso 18%, back torso 18%, and genital area 1%). This helps medical professionals assess the severity of the burn and determine the necessary treatment.

Example Calculation

Let's consider an example:

Using the formula to calculate the Rule of Nines:

\[ \text{RoN} = \left( \frac{27 \times 9}{100} \right) = 2.43\% \]

This means that the percentage of the body burned according to the Rule of Nines for this scenario is 2.43%.
