Determination of cardiovascular parameters from bioimpedance signal

摘要

The aim of this study is to denoise the bioimpedance signal and to calculate cardiovascular parameters from the thoracic cardiovascular signal. To achieve these goals, we present a de-noising operation that remove noise without losing or reducing the bioimpedance signal. After that, we have designed an algorithm determine and pick-up some cardiovascular parameters including cardiac output, arterial compliance and instantaneous arterial pressure signal in the aorta. Hence, we developed several models to help physicians in their diagnostic table improvement.
