A viscoelasticity profile is produced to assess the flow properties of the blood at various stage of the cardiopulmonary bypass procedure. The profile is obtained by measuring the pressure-to-flow relation with the blood sample confined in a cylindrical capillary tube and subjected to sinusoidal oscillatory flow near the pulse rate. At low strains, the red cells are largely in random aggregates and at high strains, the cells form layers separated by plasma. The change is accompanied by reduction of both the viscosity and elasticity.
