Modeling of newborn breathing patterns using electrical impedance tomography

The article presents the results of experimental studies aimed at modeling five basic breathing patterns of newborns using an electrical impedance tomograph and a simplified physical model of the neonatal mediastinum. The study covers such patterns as normal breathing (eupnea), periodic breathing, tachypnea, breathing with retractions and central apnea. The previously developed simplified physical model of the neonatal mediastinum is equipped with a controlled air filling system, which allows reproducing various volumes and modes of ventilation. Experimental studies confirmed the possibility of modeling and recording each of the five breathing patterns using an electrical impedance tomography. The developed technique allows research and testing of new data processing algorithms in the field of electrical impedance tomography of the lungs of newborns. The results confirm that electrical impedance tomography is a promising tool for diagnosing and monitoring respiratory disorders in newborns. The proposed solutions can be used to develop new approaches to the diagnosis and treatment of respiratory diseases in neonatology.
