Impedance Pneumograph법을 이용한 호흡 감시장치의 개발

Development of Respiration Monitor using Impedance Pneumograph

In this paper we developed a respiration monitor by an impedane pneumography. This technique, measuring the electrical impedance change of the lungs due to breath, provides the accurate data for the respiration trend and rates. To measure the small impedance difference we designed a special current source which was considered the electrical safety and the interference with the ECG signal.
