WebJan 1, 2015 · Blood viscosity was measured at 225 s −1 with a cone plate viscometer. The hematocrit-to-blood viscosity ratio (HVR), i.e. an index of red blood cell (RBC) oxygen transport effectiveness, was calculated. RBC deformability was determined at 30 Pa by ektacytometry, and RBC aggregation properties by syllectometry. Web• Aggregation & dis-aggregation: Syllectometry – Extent of aggregation, aggregation kinetics and tendency • Oxygenscan; Measuring the relative oxygen pressure at the critical point the red blood cells start to sickle . Deformability. Red blood cell deformability, expressed as the Elongation Index (El), is presented in a deformability curve.
