Experimental dependences of measurement data on the volume of inhaled air in multi-frequency electrical impedance tomography

This paper proposes an approach to modeling the process of artificial ventilation of human lungs by their controlled filling with a fixed volume of air, using an incentive spirometer Coach 2. This makes it possible to simulate the ventilation process for a healthy person and to link the assigned res...
