A secondary aim was to determine accuracy of targeted ultrafiltration rates (UFR) compared to calculated delivered UFR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>An ex vivo study with a single Phoenix\u00ae X36 platform and canine packed red blood cells (pRBC) was performed. Through dilution and UF, clinically applicable PCV values were obtained and compared to Crit-Line\u00ae hematocrit (Hct). Blood volume was constantly measured and compared to targeted UFR. Systematic and proportional bias were calculated using a Bayes method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Crit-Line\u00ae III and IV reported Hct was significantly lower than PCV (n\u2009=\u2009140, median 26%, range, 8%-50%) when PCV was &amp;gt;25% and\u2009&amp;gt;30%, respectively. Crit-Line\u00ae III and IV calculated change in blood volume (\u0394BV%) was significantly different from measured blood volume changes at \u0394BV% \u00b120% and\u2009&amp;gt;\u221220%, respectively.
