Fig. 2From: Effects of hydrophilic polymer-embedded membrane on permeability and cell adhesion during continuous hemofiltrationChanges in a hematocrit (Ht), b total protein concentration (TP), c activated clotting time (ACT), and d heparin infusion rate of circulating blood during the CHF experiments. The Ht and TP levels remained unchanged throughout the CHF experiments. The ACT was maintained within a range of 300–400 s. The heparin infusion rate/ACT was significantly decreased for both membranes after 24 h of circulation. Data are expressed as the mean ± SD, n = 8Back to article page
