Method and apparatus for monitoring of cardiopulmonary parameters using electrical impedance tomography

摘要

The present invention relates to a method and apparatus for monitoring cardiopulmonary function using electrical impedance tomography, and more particularly, by using a single monitoring device, real-time monitoring of pulmonary collapse and overexpansion in a mechanical ventilation treatment process, and a mechanical ventilation treatment process The present invention relates to a method and system for monitoring cardiopulmonary function using electrical impedance tomography capable of providing information on a plurality of hemodynamic diagnostic variables that are changed in real time. In the present invention, it is possible to selectively perform electrical impedance tomography of blood vessels at any part such as chest, neck, arms, legs, etc., and to monitor hemodynamic diagnostic variables including stroke volume, cardiac output, peripheral vascular resistance, and the like. In addition, the present invention can monitor in real time state variables for each area of the lung, including lung elasticity data, respiratory delay data, and the like, using the same monitoring device.
