Abstract
Systems and methods for determining lung impedance of a subject by acquiring multiple impedance measurements from different areas of a thorax of the subject, using multiple electrical circuits, each electrical circuit comprising a pair of electrodes attached at different locations over the thorax of the subject. The acquisition of impedance measurements of all of the electrical circuits is done at the same timing-position(s) over the subject's breathing cycle. The acquired impedance measurements may be used to determine at least one physical characteristic associated with the respective subject. The electrical circuits may be powered by several generators outputting AC power at same or different frequencies. According to some embodiments, one of the electrical circuits, powered by one of the generators, may be continuously operated when measuring is done to be used as a timer.
