first degree (superficial)

critical in general
-face, feet, hands, genitals
-injury caused by breathing in heat, toxic chemicals, smoke, or carbon monoxide
inhalation injury
-odorless, tasteless, colorless toxic gas that results from anything containing carbon incomplete combustion
carbon monoxide
-electricity causes flames that then burn the skin; electricity does not pass through body
thermal burn
-current is most intense; electrical current enters and exits the body
contact burns
-current jumps from 1 surface to another; burning nearby skin; electricity does not pass through the body
arcing injuries; flash burns
-body heat causes perspiration which is lost from the body surface when it is changed to vapor
evaporation
loss of body heat through normal breathing
respiration
greatly increased body temperature
hyperthermia
-life threatening emergency caused by a disturbance in the body’s temperature regulation mechanism
heatstroke
-heat related emergency caused by excessive loss of water and salt through sweating, characterize by cool, clammy skin and a weak rapid pulse
heat exhaustion
- muscle spasms caused by a disturbance in the electrolyte balance of the muscles
- when body loses too much salt and other electrolytes
heat cramps
-greatly decreased body temperature
hypothermia
-damage to the tissues resulting from prolonged exposure to extreme cold
frostbite
freezing of the skin surface
frostnip
