Tomografia de impedância elétrica : novo método de avaliação pulmonar

Abstract

With the advent of ever increasing technology, the imaging techniques have been improved in order to provide more information about the various types of diseases. Currently, the electrical impedance tomography (EIT) is one such promising techniques that act incorporating the dynamic image to the study of regional lung ventilation. The TIE has advantages because it is a noninvasive technique and allowing its use several times in the same patient, it does not offer radiation. Furthermore, it is a portable device can be brought to the location that the patient is, for example, in an intensive care unit. In Brazil, there is little research with the EIT, but it has been used in patients with acute lung injury, lung cancer, pulmonary edema, pneumothorax, pulmonary emphysema, dynamic hyperinflation and to observe the position of the tracheal tube.
