Key result
An oscillometric algorithm for measuring the arterial stiffness index was developed and proven effective and reliable through clinical tests, providing a reference for determining cirrhosis levels.
An oscillometry-based algorithm for measuring arterial stiffness index was developed and validated as effective and reliable for clinical use.
May support noninvasive cirrhosis staging via arterial stiffness; leaves open larger prospective validation before clinical use.
Arterial stiffness is a very important physical parameter and the measurement to it is very important in clinic. This paper describes the principle and arithmetic of arterial stiffness index. The measuring algorithm based on oscillometric method is also discussed. The algorithm proves effective and reliable through the analysis of many cases and doing lots of clinical tests, it has been developed software under LabVIEW7.0 and applied in the hospital. Furthermore, it can give the information of the measurer’s arterial stiffness and provide reference to doctor to determine the measurer’s cirrhosis level.
