Pitfalls and limitations in the use of impedance cardiography.

Standardization of non-invasive impedance cardiography for assessment of stroke volume: comparison with thermodilution.

Since its introduction by Kubicek and colleagues, impedance cardiography has been suggested as a non-invasive, simple, safe and cost-effective method of measuring stroke volume. Several controversial reports on its validity have been published. Pitfalls of this method included the nature of the electrode system and the validity of the equations. Therefore, the purpose of this study was to compa...

Use of Impedance Cardiography in Anaesthesia and Intensive Care in Children

Impedance cardiography - Old method, new opportunities. Part I. Clinical applications.

Monitoring of cardiovascular hemodynamic changes requires a very expensive and highly specialized equipment and skilled medical personnel. Up to the present time, an inexpensive, non-invasive and easy-to-use method which, like Doppler echocardiography, magnetic resonance angiography or radionuclide imaging, would assess hemodynamics of the cardiovascular system was not available. A method known...

Portable Analyzer for Impedance Spectroscopy

− The paper presents an impedance analyzer designed for impedance spectroscopy of objects located in the field. The use of the specialized microsystem AD5933 was assumed. The analysis and tests of the microsystem in the configuration proposed by the manufacturer showed the limitations having meaningful influence on the impedance measurement accuracy. In order to eliminate disadvantages of the m...

قلب نگاری امپدانسی روشی برای پایش غیرتهاجمی حجم ضربه ای: یک مطالعه ی مقدماتی

 Abstract Background: Impedance cardiography (ICG) is a simple and inexpensive technique for non-invasive and continues measurement of stroke volume. Due to non-invasive nature, ICG is becoming increasingly used in research and clinical applications. With regard to lack of domestic impedance cardiograph and limited similar imported products in the country, an inexpensive and portable protot...
