Mechanically ventilated infants with respiratory distress syndrome often develop secondary lung injury. Although special attention is paid to lung-protective ventilation strategies and non-invasive ventilation methods, easy-to-use, radiation-free technique is needed for their optimization and pulmonary ventilation distribution monitoring at the bedside. Only few years ago electrical impedance tomography was started to use in clinical neonatology. This new method of patient examination and long-term monitoring has shown great potential for individualizing neonatal respiratory support and reducing the incidence of mechanical ventilation-related adverse effects. This article presents the first clinical case in Baltic countries of preterm neonate examined with electrical impedance tomography (Swisstom BB2, Switzerland) and literature review introducing the experience of other countries in this innovative field.

Keywords: electrical impedance tomography, mechanical lung ventilation, non-invasive respiratory support, respiratory distress syndrome, preterm neonates.
