What percentage does the back cover of an adult's body surface area?

The back cover of an adult's body surface area accounts for 18%. This measurement comes from the "Rule of Nines," which is a system used in estimating body surface area involved in burns or other injuries. According to this rule, the body is divided into sections that represent approximately 9% (or multiples of 9%) of total body surface area.

For adults, the back (including the posterior aspect of the body from the neck to the lower back) is allocated a value of 18%. This is significant for assessing fluid resuscitation needs and the severity of burns. Understanding this measurement helps EMTs and other healthcare providers make informed decisions in the field regarding treatment and prioritization of care for injured patients.

The other percentages do not correspond with established guidelines for adult body surface area assessment. The accurate percentage of 18% is key in ensuring consistent and effective care.
