MOF, multi-organ failure, is a highly complex condition. However, there is one mechanism that is common: that is when the body sustains a blow and an autodestructive inflammatory response occurs throughout the body, known as Systemic Inflammatory Response Syndrome (SIRS).
After SIRS sets in, symptoms worsen, leading to multi-organ failure.
Although Richard couldn't be certain he was experiencing this, he didn't dare take it lightly because once true multi-organ failure occurs, even in the most advanced hospitals on modern Earth, there is a very high chance of death—let alone in a world much like the medieval era.
Generally speaking, if it's a single organ failure, the mortality rate can reach around 30%.
With two organs failing, the mortality rate is about 50%.
Three organs failing, the mortality rate exceeds 75%.
Four organs failing, the mortality rate… 100%.
