Evaluation of Fluid Resuscitation in Shocked Patients by Electrical Cardiometry in Comparison to Transthoracic Echocardiography.

Electrical cardiometry (EC), based on thoracic electrical bioimpedance, can measure SV continuously and non-invasively. The EC"s working principle of estimation of SV is to utilize changes in thoracic electrical impedance, which is mainly influenced by erythrocyte orientation and peak flow velocity in the ascending aorta throughout the cardiac cycle. Electrical cardiometry (EC) has been validated to monitor SV and other hemodynamic parameters non-invasively compared to different techniques such as thermodilution technique, transesophageal Doppler echocardiography and cardiac catheterization including critically ill patients, intra-operative settings, in pregnant women, in children with congenital heart diseases, even in obese children
