Q: What does FFP/RBC ratio mean in massive transfusion?

Answer:  Trauma literature  regarding  Massive Transfusion Protocol (MTP) lean towards higher FFP:RBC ratio. The thought process behind this approach is that the body's physiologic response to major trauma results in the triad of acidosis, hypothermia and coagulopathy, which eventually results in further massive blood loss. Replacement of coagulation factors may result in better control of bleeding.
