Abstract:
Objective To evaluate the non-invasive cardiac output measurements by electric impedance in critically illpatients. Methods Cardiac output measurements by impedance and Doppler ultrasonography were performed in 38 pa-tients in ICU. Results There was a significant correlation (r =0. 908 ) between impedance and ultrasonography for car-dio output measurement. Conclusion There is close agreement between electric impedance and ultrasonography in themeasurement of cardiac output in the patients. The electric impedance measurement is a noninvasive,feasible, handy, con-tinuous and cheap measurement of cardiac output.
