Blood collection systems and methods that derive estimated effects upon the donor's blood volume and hematocrit

摘要

Blood processing systems and methods convey blood drawn from a donor through a blood processing circuit to separate the blood into at least one targeted blood component for collection. The systems and methods derive an estimated effect of the procedure upon the donor. The estimated effect can be expressed in terms of a net blood fluid volume loss, or as a hematocrit of the donor after completion of the desired blood collection procedure. The systems and methods present the estimated effect to an operator for viewing, reading, or offloading.
