How is sepsis diagnosed?

Sepsis is : A syndrome consisting of bacteremia, fever or hypothermia, elevated or depressed WBC count, low blood pressure, and shock. Any combination of the foregoing, depending on severity, can be sign of sepsis.

Sepsis: This is defined as fever (or hypothermia), rapid pulse (>90/min), rapid respirations (>20/min), and elevated or suppressed WBC counts. Any two of these criteria, if caused by infection, yields a diagnosis of "sepsis". This is very specific. If you have low blood pressure not responding to fluids then you have septic shock. If more than one organ system is failing =multiorgan failure.
