Abstract

The use of a conicylindrical viscometer in the measurement of blood viscosity has been investigated. Measurements at constant rates of shear and in situations of changing shear rate were performed. The practical details involved in blood measurement and the effect of packed cell volume and plasma fibrinogen concentrations on blood viscosity are described.

Sommaire

Des recherches ont été effectuées concernant l'utilisation d'un viscomètre pour mesurer la viscosité du sang. On a fait des mesures å des taux de cisaillement constants et dans différents états d'évolution de ce taux. Les détails pratiques de la mesure du sang et l'effet du volume de cellule comble et des concentrations de plasma fibrinogène sur la viscosité du sang sont décrits.

Zusammenfassung

Der Einsatz eines konisch-zylindrischen Viskometers zur Messung der Blutviskosität wurde untersucht. Es wurden Messungen bei konstanter und wechselnder Schergeschwindigkeit vorgenommen. Hier wird beschrieben, welche praktischen Einzelheiten bei der Blutmessung zu berücksichtigen sind und wie sich ein volles Zellvolumen sowie Fibrinogen-Konzentrationen im Plasma auf die Blutviskosität auswirken.
