Sepsis or blood poisoning is a deadly condition characterized by whole-body inflammation caused by an infection that is usually in the blood and another organ, such as the lung. It is the second-leading cause of death in ICUs and the tenth-most-common cause of death overall. It occurs in up to 2% of all hospitalizations and accounts for as much as 25% of ICU bed utilization with mortality rates ranging from 20% for sepsis, 40% for severe sepsis, to over 60% for septic shock (usually sepsis with dangerously low blood pressure and other symptoms.) Its most common victims are children. I have written about sepsis before.
