The Role of Electrical Impedence Tomography in Mechanical Ventilation in Children
Electrical Impedence Tomogrpahy (EIT) uses changes in electrical impendence between air-filled versus tissue or fluid-filled spaces in order to characterize and quantify regional distribution of lung volume at the bedside. EIT-derived parameters have been used to differentiate atelectatic, overdistened, and adequately recruited lung in different lung regions by a number of investigators. Despite the ability of EIT to monitor regional lung behavior, the use of EIT derived indices has not been shown to improve outcomes in animals or humans with acute lung injury until last year when Drs. Wolf, Arnold and colleagues developed an EIT guided mechanical ventilation strategy that demonstrated promise in an animal model. Through this translational model they were able to demonstrate that EIT guided ventilation was superior to a national and standardized ventilation protocol called Acute Respiratory Distress Syndrome Network (ARDSNet) Ventilator Protocol.
