"Filtrate Replacement Fluid" (FRF) or "Ultrafiltrate Replacement Fluid" (UFRF) refers to any fluid used in a perfusion procedure, perfusion circuit, and/or perfusion process. Typically, a FRF is supplied into a perfusion circuit in relation to an amount of filtrate and/or ultrafiltrate removed from the perfusion circuit. In certain embodiments, FRF is infused into the perfusion circuit at substantially the same rate as filtrate and/or ultrafiltrate is removed from the perfusion circuit. In another embodiment, FRF is infused into the perfusion circuit at a greater rate than filtrate and/or ultrafiltrate is removed from the perfusion circuit. In another embodiment, FRF is infused into the perfusion circuit at a lesser rate than filtrate and/or ultrafiltrate is removed from the perfusion circuit. FRF can include a variety of materials and can be a mixture and/or a composition. Examples of FRF include, but are not limited to, a blood plasma, natural donor blood, blood products that have been processed to remove certain blood products such as leukocytes and/or platelets, blood substitutes, synthetic perfusates, and the like.
