Abstract

For the purpose of measurement and evaluation of arterial stiffness, we design a noninvasive medical device based on the oscillometric method and the pulse wave velocity (PWV) method, and employ arterial stiffness index (ASI) and PWV as accessing parameters. The inner pressure signal of cuff on the upper arm and the pulse wave signal at the tip of finger will be sampled, and the special software can utilize these signals to calculate two accessing parameters and obtain the evaluation conclusion of arterial stiffness. The clinical experiments show that this medical device and evaluation method are effective and valuable.
