Plasma from a unit of WB can be removed at any time during the storage period of the WB unit or up to 5 days after the unit outdates. This plasma can be stored for up to 5 years at −18°C or lower. Because it was not frozen within 8 hours after the WB was collected, plasma is not a satisfactory source of coagulation factors V and VIII. Although other coagulation factors are present because the plasma is removed from the WB after several days of storage, the electrolyte concentrations of the plasma will reflect those of stored WB. Liquid plasma is becoming more common because it has a longer shelf life compared with TP. It does not need to be thawed and is used as a “bridge” to TP for initial treatment in massively hemorrhaging protocols [60].
