Abstract :
Removing cardiogenic artifact from ventilation signals is important for improving the reliability of apnea monitors. In this study, we analyzed signal models for impedance ventilation and ECG measurements and developed a special adaptive filter system to demodulate respiratory influence on the ECG. The results show that the system can successfully cancel cardiogenic artifact in impedance pneumography
