DEVICE AND METHOD FOR MONITORING CARDIAC OUTPUT USING IMPEDANCE OF BOTH HANDS

The present invention relates to a device and a method for monitoring a cardiac output using the impedance of both hands, and aims to measure the cardiac output through the impedance change of every cardiac cycle and to obtain high-resolution evaluation data on the function of the circulatory system using hand-grip electrodes. To this end, the present invention provides a device for monitoring a cardiac output using the impedance of both hands, the device comprising: a current supplying unit, which generates an in vivo electric impedance by leading-in a current to an area to be measured using each of the hand-grip type current electrodes; an ICG detection unit, which detects ICG data based on the changes of the in vivo electric impedance by measuring the potential difference, caused by the current lead-in in the area to be measured, using each of voltage electrodes; a main control unit, which controls the operation of the ICG detection unit and extracts from ICG data a parameter for an evaluation of the function of the entire circulatory system; and a display unit, which operates by the control of the main control part and indicates the ICG data and the parameters calculated by the main control unit. Therefore, the present invention can non-invasively evaluate the epidemiological function of the heart and minimize the restraints caused by the electrodes attaching to the chest.
