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.

WebSyllectometry is a measuring method that is commonly used to assess red blood cell (RBC) aggregability. In syllectometry, light is incident on a layer of whole blood initially exposed to shear flow. The backscattered light is measured after abruptly stopping the driving mechanism. The resultant time-dependent intensity plot is called the syllectogram. … WebThe well known flow dependence of the optical density of whole blood was studied by measuring light transmission of blood in viscometric flow.
