Identification of Stiffness of Blood Vessel by Using an Analytical Model of Pulse Wave on the Measurement of Blood Pressure

Abstract

Arteriosclerosis causes myocardial infraction and cerebral infraction. However, it is difficult to know extent of its progress before it causes diseases. In order to overcome this problem, we consider a possibility of identification of stiffness of a blood vessel by using automatic sphygmomanometer. To identify stiffness of a blood vessel, we use a concentrated mass model to analyze a pulse wave. We confirm the validity of this model by an experiment with a silicon tube simulated a blood vessel. Results of this model agree well with the experimental results. Furthermore, we consider a possibility of identification of stiffness of a silicon tube by using this model.
