How to use sepsis

Sepsis is a technical medical term used in clinical, healthcare, and scientific contexts to describe a life-threatening condition where the body's response to infection causes tissue damage. It is more precise than the older term 'blood poisoning' and is the standard terminology in modern medicine. The condition exists on a spectrum from sepsis to severe sepsis to septic shock.
