The Spectra Optia® Apheresis System RBCX Calculation Tool is intended to help medical professionals who are responsible for prescribing and performing red blood cell exchange (RBCX) procedures to estimate the volume of replacement fluid required to perform a procedure on the Spectra Optia system.

It can also determine whether a custom prime is recommended. While the tool is intended to help prepare for a procedure, it is not intended to be used for making medical decisions. Use of the Spectra Optia® Apheresis System RBCX Calculation Tool on iOS requires iOS version 14.0 or above. For more information about the tool, see the About page.
