Abstract :
The electrical impedance rheopneumography (EIR) is a technique for observing the rhythmic changes of the pulmonary circulation and as such application potential for monitoring and diagnosing cardiopulmonary diseases. It is gaining popularity in China due to its non-invasive nature and low cost. However, interference from the heart, systemic circulation, respiration and the current sources is always a problem. Earlier effort had quite successfully suppressed the respiration artefact and the interference due to the heart and major systemic vessels. Here, the authors present a single-source multi-channel impedance measurement system for real-time observing the rhythmic change of the pulmonary circulation from the right/left lung, the heart, and abdomen
