Blood plasma is the liquid component of blood, in which the blood cells are suspended. Plasma is the largest single component of blood, making up about 55% of total blood volume. The term serum refers to blood plasma in which clotting factors (such as fibrin) have been removed. Blood plasma contains many vital proteins including fibrinogen, globulins and human serum albumin.

Fresh frozen plasma (FFP) is prepared from a single unit of blood. It is frozen after collection and can be stored for one year from date of collection. FFP contains all of the coagulation factors and proteins present in the original unit of blood. It is used to treat coagulopathies from warfarin overdose, liver disease, or dilutional coagulopathy. FFP that has been stored more than a standard length of time is re-classified as simply "frozen plasma", which is identical except that the coagulation factors are no longer considered completely viable.

Dried Plasma was needed for the armed forces to help prevent breakage and made transport, packaging, and storage much simpler. The dried plasma package came in two tin cans containing 400 cc bottles. One bottle contained enough distilled water to completely reconstitute the dried plasma contained in the other bottle. In about three minutes, the plasma would be ready to use and could stay fresh for around four hours.
