Calculating AC
concentration in
the final product
The concentration of anticoagulant solution found in an MCS+ platelet or plasma
product depends on a combination of the following two variables:
!
The selected anticoagulation ratio (or AC ratio) for the procedure.
!
The individual donor hematocrit.
The AC ratio is a MCS+ parameter setting which signifies the proportion between
the number of AC pump rotations to the number of Blood pump rotations during
the same time span. This ratio will determine the quantity of AC solution being
administered to the donor-line tubing as whole blood is being drawn from the
donor.
The donor hematocrit is determined prior to the collection procedure at the time
of donor blood screening.
The following table summarizes the concentration of AC in the collected plasma
or platelet product according to selected ratios for the listed donor hematocrit
values.
To determine the total volume of AC solution in a plasma or platelet final product,
the following procedure should be used:
"
Determine the concentration of AC solution in the product according to
the values listed in the following table.
"
Calculate the total volume of AC solution in collected products by multi-
plying the concentration of AC solution in the plasma or platelet product
by the volume of the final product:
AC Volume in Product =
% AC in Product
x Product Volume
