Determination of yield point: methods and review

H Kiesewetter, H Radtke, F Jung

    Biorheology
    |January 1, 1982
    PubMed
    Summary

    Blood may exhibit pseudoelastic behavior, acting as a solid under minimal force. Understanding this yield point is crucial for diagnosing and treating blood flow anomalies, especially with new therapeutic options.

    Area of Science:

    • Biophysics
    • Rheology
    • Hematology

    Background:

    • Blood's mechanical properties are critical for understanding microcirculation stasis.
    • The pseudoelastic behavior of blood, or its transition from solid-like to fluid-like states, has theoretical significance.
    • Therapeutic interventions can alter blood's flow characteristics, increasing the clinical relevance of its rheological properties.

    Purpose of the Study:

    • To review and discuss methods for quantifying the yield shear stress of blood.
    • To highlight the increasing importance of understanding blood's pseudoelasticity in clinical practice.

    Main Methods:

    • Literature review of existing methodologies for yield stress determination in blood.
    • Discussion of the theoretical underpinnings of blood's pseudoelastic behavior.

    Main Results:

    • Multiple methods exist for quantifying blood's yield shear stress.
    • The clinical significance of blood's yield point is growing due to therapeutic advancements.

    Conclusions:

    • Clarifying blood's pseudoelasticity is vital for understanding microcirculatory phenomena.
    • Accurate quantification of yield shear stress is essential for managing flow anomalies and guiding therapeutic strategies.
