Application of electrical impedance tomography in the diagnosis and treatment of acute respiratory distress syndrome

Electrical impedance tomography (EIT) is an emerging imaging technology developed at the end of the last century, which has outstanding advantages such as non-invasiveness, non-radiation, smart, low cost and easy operation. This article reviews the development, principles and clinical application of electrical impedance tomography in diagnosis, decision-making of clinical management of acute respiratory distress syndrome. The article also provides suggestions for the future development of EIT in terms of more clinical research, improving technical accuracy, cost/effectiveness and training of staff.
