Abstract
A method for determining a total volume of anticoagulant required for performing a plasmapheresis procedure prior to connecting the donor to the fluid flow circuit, by determining: a total blood volume for a donor, volume of plasma to be collected, a volume of anticoagulant that will be collected together with the plasma and estimating a separation efficiency for the blood separator. Then calculating volume of anticoagulant to be returned to the donor based on the separation efficiency, total volume of anticoagulant to be used and suggesting and attaching either a single container or multiple containers of anticoagulant based on said calculations. The system comprises a touch screen for receiving input and providing said calculation of a total volume of anticoagulant needed for the procedure, and recommendation the number of containers of anticoagulant needed.
