Because of its noninvasive, long term suitability, easy utilization and continuous monitoring of hemodynamic function it has been widely accepted [5]. Impedance Cardiography (ICG) is a straightforward, economical and noninvasive strategy to screen electrical impedance change of thorax which is created by occasional change of blood volume in aorta [6]. A proper thorax model can be utilized for assessing Stroke Volume (SV), Cardiac Output (CO) and other hemodynamic parameters [7]. The ICG signal is impacted for the most part by movement artifact and respiratory artifact. Respiratory artifact is fundamentally brought about by changes of thoracic volume amid breathing, while movement artifact is generally created by body developments and muscle contraction [8]. The frequency range of respiratory and movement artifacts incompletely cover with frequency range of the ICG signal, so it is basic to evacuate every one of the artifacts [9]. The electrical impedance change brought on by blood volume change in aorta commonly represents 2-4% of the base impedance (for the most part around 20ohm), while the electrical impedance change created by the respiratory artifact and movement artifact might be 30% or considerably more
