Abstract: The viscoelastic properties of blood serum were measured by means of a capillary viscometer described in earlier papers by the authors. The capillary viscometer constructed earlier was further modified by the use of Teflon as part of the capillary section. Changes in viscosity and recoverable shear strain were determined as a function of time on samples from patients who underwent open heart surgery. The measured values showed marked changes in both viscosity and elastic shear modulus immediately following, and for some time after, surgery.
