Introduction: Trauma is acute illness of variable severity; there are sudden and unexpected changes secondary to bleeding; there are more and more patients suffering trauma in the world. Kubiek showed that sending a constant electric current parallel to the spine could asees the amount of fluid passing through the aorta; and thereby, supported by Ohm's law resistance to flow at alternating current so called transthoracic bioimpedance. It is possible to describe the hemodynamic changes that occurred immediately, although there are many parameters were measured to valid the method, cardiac output, vascular resistance and total thoracic fluid. Objective: Demonstrate that bioimpedance can be applied to TRAUMA, in patients who have lost volume, which are found in systemic response and compensatory mechanisms. Material and methods: Niccomo bioimpedance monitor was used in 20 patients with homogeneous situations from 01 April to 31 July 2014 in sex, age, weight and volume loss. Results: Despite being of subjects in clinical similarity, there were significant changes in the parameters measured in response to hypovolemia; however, cardiac output below 4l/min and high percentage of thoracic fluid were associated with death. Without taking into account otters parameters, for purposes of this study is significant in hypovolemia the use of bioimpedance.

Keywords : Bioimpedance; cardiac output; vascular resistance; thoracic fluids.
