What percentage is the head for an adult/adolescent?

For an adult or adolescent, the head is typically considered to account for approximately 9% of the total body surface area in burn assessment protocols such as the Rule of Nines. This assessment is used by EMS providers and medical professionals to evaluate the extent of burn injuries and to determine fluid resuscitation needs. The Rule of Nines divides the body into sections, assigning a percentage to each area for quick calculations during emergency care situations. A correct understanding of these percentages is crucial for effective treatment protocols and patient care management.
