Burns

Burns:

Critical burns that need immediate medical attention include those where breathing difficulty is present, where more than one body part is affected, or where the head, neck, hands, feet, or genitals are involved. All chemical, explosion, electrical, and third-degree burns, especially if they cover more area than the palm of your hand, should be evaluated by a medical professional.
ASSESSMENT. Burns are categorized by the extent of damage to the skin or underlying tissue. First-degree burns are the least critical; they cause reddening of the skin without blistering. Second-degree burns cause damage to the superficial (outer) and the internal (inner) layers of skin, creating bubble-like sores (blisters) that contain clear, watery liquid. Third-degree burns are the most severe and most damaging of all burns; the destruction of all layers of skin occurs and the burnt area is left open and charred. When applying first-aid concepts to burns, the rescuer must quickly assess the extent of damage to the person's skin. The rescuer needs to determine through assessment what to do next.
