What is in FFP and Cryo?
FFP is made from plasma which is separated from donor blood and frozen to minus 35° Centigrade to preserve it. Cryo is made from FFP which is frozen and repeatedly thawed in a laboratory to produce a source of concentrated clotting factors including Factor VIII, von Willebrand factor and fibrinogen.
Do blood clot symptoms come and go?

What are packed RBC’s and why are they transfused instead of whole blood?
Bag of packed red blood cells. Packed red blood cells, also known as packed cells, are red blood cells that have been separated for blood transfusion. The packed cells are typically used in anemia that is either causing symptoms or when the hemoglobin is less than usually 70–80 g/L (7–8 g/dL).
