Abstract

We have developed a bioimpedance measurement system for impedance cardiography and pneumography. The system injects 50kHz, $200mA_{p-p}$ curreng into the thorax and measures the voltage changes using body surface electrodes. We used the four-electrode method for tile measurement of cardiac singnals and two-electrode method for respiratory signals. We developed a Microsoft Windows program for the acquisition, display, storage, and processing of impedance signals.
