What percentage does each arm of a child represent in body surface area?

In pediatric patients, each arm typically represents 9% of total body surface area when using the Lund and Browder chart or the Rule of Nines for quick estimation of burns and other injuries. This percentage is critical for calculating fluid resuscitation needs in cases of severe burns or trauma, as well as for assessing other medical conditions requiring body surface area calculations.

Understanding the specific body surface area percentages for various parts of a child’s body helps emergency medical technicians (EMTs) to quickly and accurately estimate the extent of injury, particularly in the context of burns, which can directly impact treatment decisions and outcomes.
