“…In several studies, EIT was applied in patients who breath spontaneously after surgery . Furthermore, results obtained in awake patients with lung cancer by EIT are in accordance with the ventilation scintigraphy estimating a left‐right division of ventilation . Being radiation‐free and having a higher time resolution makes EIT a favorable method.…”

Patients undergoing intrathoracic procedures have the highest risk of developing post-operative pulmonary complications (PPCs) 1-3 that increase hospital stay and mortality. 4 After lobectomy, post-operative lung function tests, like forced vital capacity, are reduced for months. 5,6 In patients with sublobar resections, pulmonary function is diminished only for a few days post-surgery. 6,7 Pulmonary electrical impedance tomography (EIT) is a bedside application that indicates changes of the regional distribution of lung ventilation. 8 Thus, the differential ventilation of the left and the right lung in ventilated patients can be discriminated. 9-11 In several studies, EIT was applied in patients who breath spontaneously after surgery. 12-14 Furthermore, results obtained in awake patients with lung cancer by EIT are in accordance with the ventilation scintigraphy estimating a left-right division of ventilation. 15,16 Being radiation-free and

“…The distribution of ventilation was measured using an EIT device (Goettingen Goe-MF II EIT System; Viasys/Carefusion, Germany). EIT is an emerging radiation-free, non-invasive imaging tool that is well validated and able to detect regional changes in ventilation in the lungs reliably and reproducibly (Bodenstein, David & Markstaller 2009 ; De Lema et al 2008 ; Frerichs et al 2007 ; Reifferscheid et al 2011 ; Victorino et al 2004 ).…”

BackgroundPositioning of ill children is often used to optimise ventilation–perfusion matching, thereby improving oxygenation.ObjectivesTo determine the effects of supine and prone positions, and different head positions, on the distribution of ventilation in healthy, spontaneously breathing infants and children between the ages of 6 months and 9 years.MethodsElectrical impedance tomography measurements were recorded from participants in supine and prone positions. Head positions included the head turned to the left and right in supine and prone positions, and in the midline in the supine position. Distribution of ventilation was described using end-expiratory–end-inspiratory relative impedance change.ResultsA total of 56 participants (boys = 31 [55%]; girls = 25 [45%]) were studied. The dorsal lung was significantly better ventilated than the ventral lung (P < 0.001) in both body positions. The majority of participants (83%) had greater ventilation in the dorsal lung in both positions, whilst five participants (10%) demonstrated consistently better ventilation in the non-dependent lung in both positions. Head position had no effect on the distribution of ventilation.ConclusionsThis study demonstrates that the distribution of ventilation in healthy, spontaneously breathing infants and children in supine and prone positions is not as straightforward as previously thought, with no clear reversal of the adult pattern evident.

“…Electrical impedance tomography (EIT), however, allows for non‐invasive, radiation‐free imaging, which may be particularly suited to this population. EIT has been well validated and has repeatedly been found to reliably detect changes in ventilation within the lungs . EIT can be used for extended periods of time with no known harmful effects or the need for sedation .…”
