<p>Transthoracic electrical admittance cardiography is a practical method for non-invasive and continuous monitoring of stroke volume and cardiac output (CO). The dynamic calibration of a transthoracic electrical admittance cardiograph was needed for CO calibration. Because the cardiography signal includes the time derivative of admittance variation. In this study, we have therefore developed a new cardiac admittance simulator using photoresistor that can be used for dynamic calibration of a transthoracic electrical admittance cardiograph. We proposed the approximate calibration procedure for dynamic calibration using the developed admittance simulator. We have compared the formulae using the approximate calibration procedure and smoothing on time derivative. As a result, the approximate calibration formulae agreed well with the formulae using smoothing on time derivative, which suggests that the approximate calibration is available for the dynamic calibration of transthoracic electrical admittance cardiograph.</p>
