Science Education: Physical Trauma and Sepsis

Heart rate irregularitiesStudies on physical trauma and sepsis, the body's overwhelming immune response to severe injury or infection, focus on questions like:

  • What changes occur immediately and over time when a person is critically ill or injured?
  • Why does the immune system go into overdrive?
  • How can we improve diagnosis and treatment strategies?

Follow the links below to learn more about physical trauma and sepsis,including recent developments, and read profiles of researchers working in these areas.
