Case Study Introduction
Paramedics respond to a 911 call regarding a 70-year-old female who has been pulled by neighbors out of her burning house. The fire truck is already on scene extinguishing the house fire, which is believed to have been started by a cigarette. The woman is known to smoke while watching television and is believed to have fallen asleep. She was found lying on the living room sofa, which was nearly engulfed in flames when the neighbors entered the home, as were the curtains behind it.
When paramedics arrive, the woman is on the front lawn, covered by a sheet donated by one of the neighbors. Upon initial assessment by the paramedics, the woman has first, second, and third-degree burns over more than 40% of her body.
A visual inspection notes that some of the burns on her arms and shoulders are second-degree burns, as noted by their appearance; red and blistered, involving all layers of the epidermis and upper layers of the dermis. Burns on her torso are full-thickness and appear greyish-white in color with blackened edges. The edges of the skin have peeled back on
