rules of nines

used to estimate surface area of a burn the body
surface is divided into areas representing 9% or multiples
estimating surface area of a burn is critical for determining
appropriate fluid replacement

Burns are considered very critical if:

over 25% of the body has 2nd degree burns over 10% of
the body has 3rd degree burn 3rd degree burns are present
on the hands, feet, face, perineum
