P/N 39551-00, Rev. F
Expected
Extracorporeal
Volume
The maximum Extracorporeal Volume (ECV) per cycle can be estimated by sub-
tracting the volume of anticoagulant used from the volume processed and divid-
ing by the cycle number. The most accurate estimation is obtained during the
first return mode.
Table 7-2 gives the expected maximum extracorporeal blood volume and extra-
corporeal red cell volume as a function of the donor’s hematocrit for platelet pro-
cedures. The maximum EC red blood cells is the total volume of red cells
expected to be in the disposable at the start of the return mode. The maximum
volume of red cells in the LN 994 disposable does not exceed 190 ml.
Note: These volumes do not include any blood samples taken prior to the pro-
cedure.
Note: Individual charts for expected extracorporeal volume for protocols other
than platelets are given in the individual protocol manuals.
