Electrical impedance measuring apparatus

摘要

An electrical impedance measuring apparatus includes: a plurality of electrodes adhered to a periphery of a chest of a living body; a potential measurer configured to perform a process of applying a current to any ones of the electrodes, and measuring potentials by means of other electrodes; an impedance acquirer, based on the applied current and the potentials obtained by the potential measurer, configured to obtain information related to an impedance of each of meshes, a chest section divided into the meshes; and an average value calculator configured to obtain a whole-region average value of impedances of all meshes of the chest section, and configured to obtain an ROI average value of impedances of meshes contained in each of ROIs, a whole region of the chest section segmented into the ROIs.

1. An electrical impedance measuring apparatus comprising:
a plurality of electrodes which are adapted to be adhered to a periphery of a chest of a living body; a potential measurer having a controller and which is configured to perform a process of applying a current to any of the electrodes, and measuring potentials by means of other electrodes, on all of the electrodes while changing the electrodes to which the current is to be applied; and a computer having a processor and memory, and being configured to:
based on the applied current and the potentials obtained by the potential measurer, obtain information related to an impedance of each of a plurality of meshes, a chest section being divided into the meshes;obtain a whole-region average value of impedances of all meshes of the chest section, and which is configured to obtain a region of interest (ROI) average value of impedances of meshes contained in each of a plurality of ROIs, a whole region of the chest section being segmented into the ROIs; andcause waveforms of the whole-region average value and the ROI average value to be displayed on a same time axis on a display.
