What is TRAUMA?

• Trauma is an injury caused by a physical force.
  Most often the consequences of motor vehicle
  crashes, falls, drowning, gun shots, fires and
  burns, stabbing, or blunt assault.
• American Trauma Society

4
Trauma Mortality

• Trauma kills more people between the ages of
  1 and 44 than any other disease or illness.
  
• Nearly 100,000 people of all ages in the
  United States die from trauma each year.
• According to the National Center for Heath
  Statistics, trauma (unintentional injuries
  homicides) causes
• 43 of all deaths from age 1 to 4
• 48 of all deaths in ages 5 to 14
• 62 of all deaths in ages 15 to 24

• 1966 The National Highway Safety Act (P.L.
  89-564) established national standards for
  training emergency medical technicians, and
  minimum equipment required on an ambulance
• Established the Department of Transportation as
  the lead federal agency to advance trauma safety,
  prehospital care, and acute care.
