  • Title: A computational method for calculating distensibility of the blood vessel in vivo.
    Author: Tewari KP, Mishra RK.
    Journal: Physiol Chem Phys; 1975; 7(2):95-113. PubMed ID: 1153527.
    Abstract:
    A computational method for calculating the dynamic distensibility of the vessel wall in vivo, developed on the basis of the pressure pulse transmission, is proposed. Distensibilities of descending thoracic aorta, abdominal aorta, and femoral artery in normal dogs, and of femoral artery of a typical dog under the action of vasoactive drugs, have been calculated. In femoral artery it is compared with the values of the diameter change/pressure change. Comparison of the results clearly indicate the feasibility of the proposed method. The order of distensibility found is: descending thoracic aorta greater than abdominal aorta greater than femoral artery.
