Summary

Electrical impedance tomography (EIT) is a non-invasive, radiation-free imaging technique that measures local pulmonary ventilation and ventilation distribution through potential changes on the skin surface of the chest wall during the respiratory cycle. Recently, a global inhomogeneity (GI) index has been proposed and used to quantify the distribution of tidal volume in the lungs. Currently, there are research results showing that ventilation improves postoperative oxygenation and gas exchange when ventilation is applied during CPB, but the evidence for long-term prognosis is lacking. In this study, researchers performed electrical impedance tomography in the intensive care unit immediately after surgery on patients who had undergone endotracheal tube extubation in the operating room immediately after completing minimally invasive cardiac surgery by collapsing the right lung through right minimal thoracotomy. The purpose of this study is to measure local pulmonary ventilation and ventilation distribution using this method and to find the optimal left lung ventilation method during minimally invasive cardiac surgery based on this. Identifying the difference in postoperative pulmonary ventilation disorders and functional regional ventilation according to the pulmonary ventilation strategy at the time of CPB in minimally invasive cardiac surgery can help predict the risk of pulmonary complications and improve the prognosis of patients after surgery.
